    GSSAPI Authentication and Kerberos v5 | killexams.com existent questions and Pass4sure dumps

    This chapter is from the reserve 

    This section discusses the GSSAPI mechanism, in particular, Kerberos v5 and how this works in conjunction with the Sun ONE Directory Server 5.2 software and what is involved in implementing such a solution. gratify exist vigilant that this is not a picayune task.

    It’s worth taking a brief behold at the relationship between the Generic Security Services Application Program Interface (GSSAPI) and Kerberos v5.

    The GSSAPI does not actually provide security services itself. Rather, it is a framework that provides security services to callers in a generic fashion, with a range of underlying mechanisms and technologies such as Kerberos v5. The current implementation of the GSSAPI only works with the Kerberos v5 security mechanism. The best way to contemplate about the relationship between GSSAPI and Kerberos is in the following manner: GSSAPI is a network authentication protocol abstraction that allows Kerberos credentials to exist used in an authentication exchange. Kerberos v5 must exist installed and running on any system on which GSSAPI-aware programs are running.

    The support for the GSSAPI is made practicable in the directory server through the introduction of a unique SASL library, which is based on the Cyrus CMU implementation. Through this SASL framework, DIGEST-MD5 is supported as explained previously, and GSSAPI which implements Kerberos v5. Additional GSSAPI mechanisms upshot exist. For example, GSSAPI with SPNEGO support would exist GSS-SPNEGO. Other GSS mechanism names are based on the GSS mechanisms OID.

    The Sun ONE Directory Server 5.2 software only supports the utilize of GSSAPI on Solaris OE. There are implementations of GSSAPI for other operating systems (for example, Linux), but the Sun ONE Directory Server 5.2 software does not utilize them on platforms other than the Solaris OE.

    Understanding GSSAPI

    The Generic Security Services Application Program Interface (GSSAPI) is a criterion interface, defined by RFC 2743, that provides a generic authentication and secure messaging interface, whereby these security mechanisms can exist plugged in. The most commonly referred to GSSAPI mechanism is the Kerberos mechanism that is based on stealthy key cryptography.

    One of the main aspects of GSSAPI is that it allows developers to add secure authentication and privacy (encryption and or integrity checking) protection to data being passed over the wire by writing to a lone programming interface. This is shown in pattern 3-2.

    03fig02.gifFigure 3-2. GSSAPI Layers

    The underlying security mechanisms are loaded at the time the programs are executed, as opposed to when they are compiled and built. In practice, the most commonly used GSSAPI mechanism is Kerberos v5. The Solaris OE provides a few different flavors of Diffie-Hellman GSSAPI mechanisms, which are only useful to NIS+ applications.

    What can exist confusing is that developers might write applications that write directly to the Kerberos API, or they might write GSSAPI applications that request the Kerberos mechanism. There is a stout difference, and applications that talk Kerberos directly cannot communicate with those that talk GSSAPI. The wire protocols are not compatible, even though the underlying Kerberos protocol is in use. An instance is telnet with Kerberos is a secure telnet program that authenticates a telnet user and encrypts data, including passwords exchanged over the network during the telnet session. The authentication and message protection features are provided using Kerberos. The telnet application with Kerberos only uses Kerberos, which is based on secret-key technology. However, a telnet program written to the GSSAPI interface can utilize Kerberos as well as other security mechanisms supported by GSSAPI.

    The Solaris OE does not deliver any libraries that provide support for third-party companies to program directly to the Kerberos API. The goal is to hearten developers to utilize the GSSAPI. Many open-source Kerberos implementations (MIT, Heimdal) allow users to write Kerberos applications directly.

    On the wire, the GSSAPI is compatible with Microsoft’s SSPI and thus GSSAPI applications can communicate with Microsoft applications that utilize SSPI and Kerberos.

    The GSSAPI is preferred because it is a standardized API, whereas Kerberos is not. This means that the MIT Kerberos progress team might change the programming interface anytime, and any applications that exist today might not work in the future without some code modifications. Using GSSAPI avoids this problem.

    Another capitalize of GSSAPI is its pluggable feature, which is a stout benefit, especially if a developer later decides that there is a better authentication way than Kerberos, because it can easily exist plugged into the system and the existing GSSAPI applications should exist able to utilize it without being recompiled or patched in any way.

    Understanding Kerberos v5

    Kerberos is a network authentication protocol designed to provide tenacious authentication for client/server applications by using secret-key cryptography. Originally developed at the Massachusetts Institute of Technology, it is included in the Solaris OE to provide tenacious authentication for Solaris OE network applications.

    In addition to providing a secure authentication protocol, Kerberos also offers the aptitude to add privacy support (encrypted data streams) for remote applications such as telnet, ftp, rsh, rlogin, and other common UNIX network applications. In the Solaris OE, Kerberos can also exist used to provide tenacious authentication and privacy support for Network File Systems (NFS), allowing secure and private file sharing across the network.

    Because of its widespread acceptance and implementation in other operating systems, including Windows 2000, HP-UX, and Linux, the Kerberos authentication protocol can interoperate in a heterogeneous environment, allowing users on machines running one OS to securely authenticate themselves on hosts of a different OS.

    The Kerberos software is available for Solaris OE versions 2.6, 7, 8, and 9 in a sever package called the Sun Enterprise Authentication Mechanism (SEAM) software. For Solaris 2.6 and Solaris 7 OE, Sun Enterprise Authentication Mechanism software is included as piece of the Solaris easy Access Server 3.0 (Solaris SEAS) package. For Solaris 8 OE, the Sun Enterprise Authentication Mechanism software package is available with the Solaris 8 OE Admin Pack.

    For Solaris 2.6 and Solaris 7 OE, the Sun Enterprise Authentication Mechanism software is freely available as piece of the Solaris easy Access Server 3.0 package available for download from:

    http://www.sun.com/software/solaris/7/ds/ds-seas.

    For Solaris 8 OE systems, Sun Enterprise Authentication Mechanism software is available in the Solaris 8 OE Admin Pack, available for download from:

    http://www.sun.com/bigadmin/content/adminPack/index.html.

    For Solaris 9 OE systems, Sun Enterprise Authentication Mechanism software is already installed by default and contains the following packages listed in TABLE 3-1.

    Table 3-1. Solaris 9 OE Kerberos v5 Packages

    All of these Sun Enterprise Authentication Mechanism software distributions are based on the MIT KRB5 Release version 1.0. The client programs in these distributions are compatible with later MIT releases (1.1, 1.2) and with other implementations that are compliant with the standard.

    How Kerberos Works

    The following is an overview of the Kerberos v5 authentication system. From the user’s standpoint, Kerberos v5 is mostly invisible after the Kerberos session has been started. Initializing a Kerberos session often involves no more than logging in and providing a Kerberos password.

    The Kerberos system revolves around the concept of a ticket. A ticket is a set of electronic information that serves as identification for a user or a service such as the NFS service. Just as your driver’s license identifies you and indicates what driving permissions you have, so a ticket identifies you and your network access privileges. When you discharge a Kerberos-based transaction (for example, if you utilize rlogin to log in to another machine), your system transparently sends a request for a ticket to a Key Distribution Center, or KDC. The KDC accesses a database to authenticate your identity and returns a ticket that grants you leave to access the other machine. Transparently means that you upshot not exigency to explicitly request a ticket.

    Tickets abide unavoidable attributes associated with them. For example, a ticket can exist forwardable (which means that it can exist used on another machine without a unique authentication process), or postdated (not sound until a specified time). How tickets are used (for example, which users are allowed to obtain which types of tickets) is set by policies that are determined when Kerberos is installed or administered.

    You will frequently observe the terms credential and ticket. In the Kerberos world, they are often used interchangeably. Technically, however, a credential is a ticket plus the session key for that session.

    Initial Authentication

    Kerberos authentication has two phases, an initial authentication that allows for everything subsequent authentications, and the subsequent authentications themselves.

    A client (a user, or a service such as NFS) begins a Kerberos session by requesting a ticket-granting ticket (TGT) from the Key Distribution hub (KDC). This request is often done automatically at login.

    A ticket-granting ticket is needed to obtain other tickets for specific services. contemplate of the ticket-granting ticket as something similar to a passport. relish a passport, the ticket-granting ticket identifies you and allows you to obtain numerous “visas,” where the “visas” (tickets) are not for exotic countries, but for remote machines or network services. relish passports and visas, the ticket-granting ticket and the other various tickets abide limited lifetimes. The discrepancy is that Kerberized commands notice that you abide a passport and obtain the visas for you. You don’t abide to discharge the transactions yourself.

    The KDC creates a ticket-granting ticket and sends it back, in encrypted form, to the client. The client decrypts the ticket-granting ticket using the client’s password.

    Now in possession of a sound ticket-granting ticket, the client can request tickets for everything sorts of network operations for as long as the ticket-granting ticket lasts. This ticket usually lasts for a few hours. Each time the client performs a unique network operation, it requests a ticket for that operation from the KDC.

    Subsequent Authentications

    The client requests a ticket for a particular service from the KDC by sending the KDC its ticket-granting ticket as proof of identity.

  • The KDC sends the ticket for the specific service to the client.

    For example, suppose user lucy wants to access an NFS file system that has been shared with krb5 authentication required. Since she is already authenticated (that is, she already has a ticket-granting ticket), as she attempts to access the files, the NFS client system automatically and transparently obtains a ticket from the KDC for the NFS service.

  • The client sends the ticket to the server.

    When using the NFS service, the NFS client automatically and transparently sends the ticket for the NFS service to the NFS server.

  • The server allows the client access.

    These steps do it issue that the server doesn’t ever communicate with the KDC. The server does, though, as it registers itself with the KDC, just as the first client does.

  • Principals

    A client is identified by its principal. A principal is a unique identity to which the KDC can assign tickets. A principal can exist a user, such as joe, or a service, such as NFS.

    By convention, a principal name is divided into three parts: the primary, the instance, and the realm. A typical principal could be, for example, lucy/admin@EXAMPLE.COM, where:

    lucy is the primary. The primary can exist a user name, as shown here, or a service, such as NFS. The primary can also exist the word host, which signifies that this principal is a service principal that is set up to provide various network services.

    admin is the instance. An instance is optional in the case of user principals, but it is required for service principals. For example, if the user lucy sometimes acts as a system administrator, she can utilize lucy/admin to distinguish herself from her habitual user identity. Likewise, if Lucy has accounts on two different hosts, she can utilize two principal names with different instances (for example, lucy/california.example.com and lucy/boston.example.com).

    Realms

    A realm is a ratiocinative network, similar to a domain, which defines a group of systems under the identical master KDC. Some realms are hierarchical (one realm being a superset of the other realm). Otherwise, the realms are non-hierarchical (or direct) and the mapping between the two realms must exist defined.

    Realms and KDC Servers

    Each realm must comprehend a server that maintains the master copy of the principal database. This server is called the master KDC server. Additionally, each realm should contain at least one slave KDC server, which contains duplicate copies of the principal database. Both the master KDC server and the slave KDC server create tickets that are used to establish authentication.

    Understanding the Kerberos KDC

    The Kerberos Key Distribution hub (KDC) is a trusted server that issues Kerberos tickets to clients and servers to communicate securely. A Kerberos ticket is a conceal of data that is presented as the user’s credentials when attempting to access a Kerberized service. A ticket contains information about the user’s identity and a temporary encryption key, everything encrypted in the server’s private key. In the Kerberos environment, any entity that is defined to abide a Kerberos identity is referred to as a principal.

    A principal may exist an entry for a particular user, host, or service (such as NFS or FTP) that is to interact with the KDC. Most commonly, the KDC server system also runs the Kerberos Administration Daemon, which handles administrative commands such as adding, deleting, and modifying principals in the Kerberos database. Typically, the KDC, the admin server, and the database are everything on the identical machine, but they can exist separated if necessary. Some environments may require that multiple realms exist configured with master KDCs and slave KDCs for each realm. The principals applied for securing each realm and KDC should exist applied to everything realms and KDCs in the network to ensure that there isn’t a lone weak link in the chain.

    One of the first steps to engage when initializing your Kerberos database is to create it using the kdb5_util command, which is located in /usr/sbin. When running this command, the user has the altenative of whether to create a stash file or not. The stash file is a local copy of the master key that resides on the KDC’s local disk. The master key contained in the stash file is generated from the master password that the user enters when first creating the KDC database. The stash file is used to authenticate the KDC to itself automatically before starting the kadmind and krb5kdc daemons (for example, as piece of the machine’s boot sequence).

    If a stash file is not used when the database is created, the administrator who starts up the krb5kdc process will abide to manually enter the master key (password) every time they start the process. This may seem relish a typical trade off between convenience and security, but if the rest of the system is sufficiently hardened and protected, very slight security is lost by having the master key stored in the protected stash file. It is recommended that at least one slave KDC server exist installed for each realm to ensure that a backup is available in the event that the master server becomes unavailable, and that slave KDC exist configured with the identical plane of security as the master.

    Currently, the Sun Kerberos v5 Mechanism utility, kdb5_util, can create three types of keys, DES-CBC-CRC, DES-CBC-MD5, and DES-CBC-RAW. DES-CBC stands for DES encryption with Cipher conceal Chaining and the CRC, MD5, and RAW designators refer to the checksum algorithm that is used. By default, the key created will exist DES-CBC-CRC, which is the default encryption sort for the KDC. The sort of key created is specified on the command line with the -k option (see the kdb5_util (1M) man page). choose the password for your stash file very carefully, because this password can exist used in the future to decrypt the master key and modify the database. The password may exist up to 1024 characters long and can comprehend any combination of letters, numbers, punctuation, and spaces.

    The following is an instance of creating a stash file:

    kdc1 #/usr/sbin/kdb5_util create -r EXAMPLE.COM -s Initializing database '/var/krb5/principal' for realm 'EXAMPLE.COM' master key name 'K/M@EXAMPLE.COM' You will exist prompted for the database Master Password. It is principal that you NOT FORGET this password. Enter KDC database master key: master_key Re-enter KDC database master key to verify: master_key

    Notice the utilize of the -s argument to create the stash file. The location of the stash file is in the /var/krb5. The stash file appears with the following mode and ownership settings:

    kdc1 # cd /var/krb5 kdc1 # ls -l -rw------- 1 root other 14 Apr 10 14:28 .k5.EXAMPLE.COM

    The directory used to store the stash file and the database should not exist shared or exported.

    Secure Settings in the KDC Configuration File

    The KDC and Administration daemons both read configuration information from /etc/krb5/kdc.conf. This file contains KDC-specific parameters that govern overall conduct for the KDC and for specific realms. The parameters in the kdc.conf file are explained in detail in the kdc.conf(4) man page.

    The kdc.conf parameters picture locations of various files and ports to utilize for accessing the KDC and the administration daemon. These parameters generally upshot not exigency to exist changed, and doing so does not result in any added security. However, there are some parameters that may exist adjusted to enhance the overall security of the KDC. The following are some examples of adjustable parameters that enhance security.

  • kdc_ports – Defines the ports that the KDC will listen on to receive requests. The criterion port for Kerberos v5 is 88. 750 is included and commonly used to support older clients that noiseless utilize the default port designated for Kerberos v4. Solaris OE noiseless listens on port 750 for backwards compatibility. This is not considered a security risk.

  • max_life – Defines the maximum lifetime of a ticket, and defaults to eight hours. In environments where it is desirable to abide users re-authenticate frequently and to reduce the random of having a principal’s credentials stolen, this value should exist lowered. The recommended value is eight hours.

  • max_renewable_life – Defines the era of time from when a ticket is issued that it may exist renewed (using kinit -R). The criterion value here is 7 days. To disable renewable tickets, this value may exist set to 0 days, 0 hrs, 0 min. The recommended value is 7d 0h 0m 0s.

  • default_principal_expiration – A Kerberos principal is any unique identity to which Kerberos can assign a ticket. In the case of users, it is the identical as the UNIX system user name. The default lifetime of any principal in the realm may exist defined in the kdc.conf file with this option. This should exist used only if the realm will contain temporary principals, otherwise the administrator will abide to constantly exist renewing principals. Usually, this setting is left undefined and principals upshot not expire. This is not insecure as long as the administrator is vigilant about removing principals for users that no longer exigency access to the systems.

  • supported_enctypes – The encryption types supported by the KDC may exist defined with this option. At this time, Sun Enterprise Authentication Mechanism software only supports des-cbc-crc:normal encryption type, but in the future this may exist used to ensure that only tenacious cryptographic ciphers are used.

  • dict_file – The location of a dictionary file containing strings that are not allowed as passwords. A principal with any password policy (see below) will not exist able to utilize words organize in this dictionary file. This is not defined by default. Using a dictionary file is a beneficial way to preclude users from creating picayune passwords to protect their accounts, and thus helps avoid one of the most common weaknesses in a computer network-guessable passwords. The KDC will only check passwords against the dictionary for principals which abide a password policy association, so it is beneficial rehearse to abide at least one simple policy associated with everything principals in the realm.

  • The Solaris OE has a default system dictionary that is used by the spell program that may also exist used by the KDC as a dictionary of common passwords. The location of this file is: /usr/share/lib/dict/words. Other dictionaries may exist substituted. The format is one word or phrase per line.

    The following is a Kerberos v5 /etc/krb5/kdc.conf instance with suggested settings:

    # Copyright 1998-2002 Sun Microsystems, Inc. everything rights reserved. # utilize is topic to license terms. # #ident "@(#)kdc.conf 1.2 02/02/14 SMI" [kdcdefaults] kdc_ports = 88,750 [realms] ___default_realm___ = { profile = /etc/krb5/krb5.conf database_name = /var/krb5/principal admin_keytab = /etc/krb5/kadm5.keytab acl_file = /etc/krb5/kadm5.acl kadmind_port = 749 max_life = 8h 0m 0s max_renewable_life = 7d 0h 0m 0s default_principal_flags = +preauth Needs poignant -- dict_file = /usr/share/lib/dict/words } Access Control

    The Kerberos administration server allows for granular control of the administrative commands by utilize of an access control list (ACL) file (/etc/krb5/kadm5.acl). The syntax for the ACL file allows for wildcarding of principal names so it is not necessary to list every lone administrator in the ACL file. This feature should exist used with Great care. The ACLs used by Kerberos allow privileges to exist broken down into very precise functions that each administrator can perform. If a unavoidable administrator only needs to exist allowed to abide read-access to the database then that person should not exist granted replete admin privileges. Below is a list of the privileges allowed:

  • a – Allows the addition of principals or policies in the database.

  • A – Prohibits the addition of principals or policies in the database.

  • d – Allows the deletion of principals or policies in the database.

  • D – Prohibits the deletion of principals or policies in the database.

  • m – Allows the modification of principals or policies in the database.

  • M – Prohibits the modification of principals or policies in the database.

  • c – Allows the changing of passwords for principals in the database.

  • C – Prohibits the changing of passwords for principals in the database.

  • i – Allows inquiries to the database.

  • I – Prohibits inquiries to the database.

  • l – Allows the listing of principals or policies in the database.

  • L – Prohibits the listing of principals or policies in the database.

  • * – Short for everything privileges (admcil).

  • x – Short for everything privileges (admcil). Identical to *.

  • Adding Administrators

    After the ACLs are set up, actual administrator principals should exist added to the system. It is strongly recommended that administrative users abide sever /admin principals to utilize only when administering the system. For example, user Lucy would abide two principals in the database - lucy@REALM and lucy/admin@REALM. The /admin principal would only exist used when administering the system, not for getting ticket-granting-tickets (TGTs) to access remote services. Using the /admin principal only for administrative purposes minimizes the random of someone walking up to Joe’s unattended terminal and performing unauthorized administrative commands on the KDC.

    Kerberos principals may exist differentiated by the instance piece of their principal name. In the case of user principals, the most common instance identifier is /admin. It is criterion rehearse in Kerberos to differentiate user principals by defining some to exist /admin instances and others to abide no specific instance identifier (for example, lucy/admin@REALM versus lucy@REALM). Principals with the /admin instance identifier are assumed to abide administrative privileges defined in the ACL file and should only exist used for administrative purposes. A principal with an /admin identifier which does not match up with any entries in the ACL file will not exist granted any administrative privileges, it will exist treated as a non-privileged user principal. Also, user principals with the /admin identifier are given sever passwords and sever permissions from the non-admin principal for the identical user.

    The following is a sample /etc/krb5/kadm5.acl file:

    # Copyright (c) 1998-2000 by Sun Microsystems, Inc. # everything rights reserved. # #pragma ident "@(#)kadm5.acl 1.1 01/03/19 SMI" # lucy/admin is given replete administrative privilege lucy/admin@EXAMPLE.COM * # # tom/admin user is allowed to query the database (d), listing principals # (l), and changing user passwords (c) # tom/admin@EXAMPLE.COM dlc

    It is highly recommended that the kadm5.acl file exist tightly controlled and that users exist granted only the privileges they exigency to discharge their assigned tasks.

    Creating Host Keys

    Creating host keys for systems in the realm such as slave KDCs is performed the identical way that creating user principals is performed. However, the -randkey option should always exist used, so no one ever knows the actual key for the hosts. Host principals are almost always stored in the keytab file, to exist used by root-owned processes that wish to act as Kerberos services for the local host. It is rarely necessary for anyone to actually know the password for a host principal because the key is stored safely in the keytab and is only accessible by root-owned processes, never by actual users.

    When creating keytab files, the keys should always exist extracted from the KDC on the identical machine where the keytab is to reside using the ktadd command from a kadmin session. If this is not feasible, engage Great supervision in transferring the keytab file from one machine to the next. A malicious attacker who possesses the contents of the keytab file could utilize these keys from the file in order to gain access to another user or services credentials. Having the keys would then allow the attacker to impersonate whatever principal that the key represented and further compromise the security of that Kerberos realm. Some suggestions for transferring the keytab are to utilize Kerberized, encrypted ftp transfers, or to utilize the secure file transfer programs scp or sftp offered with the SSH package (http://www.openssh.org). Another safe way is to situation the keytab on a removable disk, and hand-deliver it to the destination.

    Hand delivery does not scale well for large installations, so using the Kerberized ftp daemon is perhaps the most convenient and secure way available.

    Using NTP to Synchronize Clocks

    All servers participating in the Kerberos realm exigency to abide their system clocks synchronized to within a configurable time restrict (default 300 seconds). The safest, most secure way to systematically synchronize the clocks on a network of Kerberos servers is by using the Network Time Protocol (NTP) service. The Solaris OE comes with an NTP client and NTP server software (SUNWntpu package). observe the ntpdate(1M) and xntpd(1M) man pages for more information on the individual commands. For more information on configuring NTP, refer to the following Sun BluePrints OnLine NTP articles:

    It is faultfinding that the time exist synchronized in a secure manner. A simple denial of service assail on either a client or a server would involve just skewing the time on that system to exist outside of the configured clock skew value, which would then preclude anyone from acquiring TGTs from that system or accessing Kerberized services on that system. The default clock-skew value of five minutes is the maximum recommended value.

    The NTP infrastructure must also exist secured, including the utilize of server hardening for the NTP server and application of NTP security features. Using the Solaris Security Toolkit software (formerly known as JASS) with the secure.driver script to create a minimal system and then installing just the necessary NTP software is one such method. The Solaris Security Toolkit software is available at:

    Establishing Password Policies

    Kerberos allows the administrator to define password policies that can exist applied to some or everything of the user principals in the realm. A password policy contains definitions for the following parameters:

  • Minimum Password Length – The number of characters in the password, for which the recommended value is 8.

  • Maximum Password Classes – The number of different character classes that must exist used to do up the password. Letters, numbers, and punctuation are the three classes and sound values are 1, 2, and 3. The recommended value is 2.

  • Saved Password History – The number of previous passwords that abide been used by the principal that cannot exist reused. The recommended value is 3.

  • Minimum Password Lifetime (seconds) – The minimum time that the password must exist used before it can exist changed. The recommended value is 3600 (1 hour).

  • Maximum Password Lifetime (seconds) – The maximum time that the password can exist used before it must exist changed. The recommended value is 7776000 (90 days).

  • These values can exist set as a group and stored as a lone policy. Different policies can exist defined for different principals. It is recommended that the minimum password length exist set to at least 8 and that at least 2 classes exist required. Most people mind to choose easy-to-remember and easy-to-type passwords, so it is a beneficial thought to at least set up policies to hearten slightly more difficult-to-guess passwords through the utilize of these parameters. Setting the Maximum Password Lifetime value may exist helpful in some environments, to coerce people to change their passwords periodically. The era is up to the local administrator according to the overriding corporate security policy used at that particular site. Setting the Saved Password History value combined with the Minimum Password Lifetime value prevents people from simply switching their password several times until they rep back to their original or favorite password.

    The maximum password length supported is 255 characters, unlike the UNIX password database which only supports up to 8 characters. Passwords are stored in the KDC encrypted database using the KDC default encryption method, DES-CBC-CRC. In order to preclude password guessing attacks, it is recommended that users choose long passwords or pass phrases. The 255 character restrict allows one to choose a tiny sentence or easy to recollect phrase instead of a simple one-word password.

    It is practicable to utilize a dictionary file that can exist used to preclude users from choosing common, easy-to-guess words (see “Secure Settings in the KDC Configuration File” on page 70). The dictionary file is only used when a principal has a policy association, so it is highly recommended that at least one policy exist in upshot for everything principals in the realm.

    The following is an instance password policy creation:

    If you specify a kadmin command without specifying any options, kadmin displays the syntax (usage information) for that command. The following code box shows this, followed by an actual add_policy command with options.

    kadmin: add_policy usage: add_policy [options] policy options are: [-maxlife time] [-minlife time] [-minlength length] [-minclasses number] [-history number] kadmin: add_policy -minlife "1 hour" -maxlife "90 days" -minlength 8 -minclasses 2 -history 3 passpolicy kadmin: get_policy passpolicy Policy: passpolicy Maximum password life: 7776000 Minimum password life: 3600 Minimum password length: 8 Minimum number of password character classes: 2 Number of musty keys kept: 3 Reference count: 0

    This instance creates a password policy called passpolicy which enforces a maximum password lifetime of 90 days, minimum length of 8 characters, a minimum of 2 different character classes (letters, numbers, punctuation), and a password history of 3.

    To apply this policy to an existing user, modify the following:

    kadmin: modprinc -policy passpolicy lucyPrincipal "lucy@EXAMPLE.COM" modified.

    To modify the default policy that is applied to everything user principals in a realm, change the following:

    kadmin: modify_policy -maxlife "90 days" -minlife "1 hour" -minlength 8 -minclasses 2 -history 3 default kadmin: get_policy default Policy: default Maximum password life: 7776000 Minimum password life: 3600 Minimum password length: 8 Minimum number of password character classes: 2 Number of musty keys kept: 3 Reference count: 1

    The Reference weigh value indicates how many principals are configured to utilize the policy.

    The default policy is automatically applied to everything unique principals that are not given the identical password as the principal name when they are created. Any account with a policy assigned to it is uses the dictionary (defined in the dict_file parameter in /etc/krb5/kdc.conf) to check for common passwords.

    Backing Up a KDC

    Backups of a KDC system should exist made regularly or according to local policy. However, backups should exclude the /etc/krb5/krb5.keytab file. If the local policy requires that backups exist done over a network, then these backups should exist secured either through the utilize of encryption or possibly by using a sever network interface that is only used for backup purposes and is not exposed to the identical traffic as the non-backup network traffic. Backup storage media should always exist kept in a secure, fireproof location.

    Monitoring the KDC

    Once the KDC is configured and running, it should exist continually and vigilantly monitored. The Sun Kerberos v5 software KDC logs information into the /var/krb5/kdc.log file, but this location can exist modified in the /etc/krb5/krb5.conf file, in the logging section.

    [logging] default = FILE:/var/krb5/kdc.log kdc = FILE:/var/krb5/kdc.log

    The KDC log file should abide read and write permissions for the root user only, as follows:

    -rw------ 1 root other 750 25 May 10 17:55 /var/krb5/kdc.log Kerberos Options

    The /etc/krb5/krb5.conf file contains information that everything Kerberos applications utilize to determine what server to talk to and what realm they are participating in. Configuring the krb5.conf file is covered in the Sun Enterprise Authentication Mechanism Software Installation Guide. also refer to the krb5.conf(4) man page for a replete description of this file.

    The appdefaults section in the krb5.conf file contains parameters that control the conduct of many Kerberos client tools. Each appliance may abide its own section in the appdefaults section of the krb5.conf file.

    Many of the applications that utilize the appdefaults section, utilize the identical options; however, they might exist set in different ways for each client application.

    Kerberos Client Applications

    The following Kerberos applications can abide their conduct modified through the user of options set in the appdefaults section of the /etc/krb5/krb5.conf file or by using various command-line arguments. These clients and their configuration settings are described below.

    kinit

    The kinit client is used by people who want to obtain a TGT from the KDC. The /etc/krb5/krb5.conf file supports the following kinit options: renewable, forwardable, no_addresses, max_life, max_renewable_life and proxiable.

    telnet

    The Kerberos telnet client has many command-line arguments that control its behavior. refer to the man page for complete information. However, there are several appealing security issues involving the Kerberized telnet client.

    The telnet client uses a session key even after the service ticket which it was derived from has expired. This means that the telnet session remains energetic even after the ticket originally used to gain access, is no longer valid. This is insecure in a strict environment, however, the trade off between ease of utilize and strict security tends to lean in favor of ease-of-use in this situation. It is recommended that the telnet connection exist re-initialized periodically by disconnecting and reconnecting with a unique ticket. The overall lifetime of a ticket is defined by the KDC (/etc/krb5/kdc.conf), normally defined as eight hours.

    The telnet client allows the user to forward a copy of the credentials (TGT) used to authenticate to the remote system using the -f and -F command-line options. The -f option sends a non-forwardable copy of the local TGT to the remote system so that the user can access Kerberized NFS mounts or other local Kerberized services on that system only. The -F option sends a forwardable TGT to the remote system so that the TGT can exist used from the remote system to gain further access to other remote Kerberos services beyond that point. The -F option is a superset of -f. If the Forwardable and or forward options are set to wrong in the krb5.conf file, these command-line arguments can exist used to override those settings, thus giving individuals the control over whether and how their credentials are forwarded.

    The -x option should exist used to swirl on encryption for the data stream. This further protects the session from eavesdroppers. If the telnet server does not support encryption, the session is closed. The /etc/krb5/krb5.conf file supports the following telnet options: forward, forwardable, encrypt, and autologin. The autologin [true/false] parameter tells the client to try and attempt to log in without prompting the user for a user name. The local user name is passed on to the remote system in the telnet negotiations.

    rlogin and rsh

    The Kerberos rlogin and rsh clients behave much the identical as their non-Kerberized equivalents. Because of this, it is recommended that if they are required to exist included in the network files such as /etc/hosts.equiv and .rhosts that the root users directory exist removed. The Kerberized versions abide the added capitalize of using Kerberos protocol for authentication and can also utilize Kerberos to protect the privacy of the session using encryption.

    Similar to telnet described previously, the rlogin and rsh clients utilize a session key after the service ticket which it was derived from has expired. Thus, for maximum security, rlogin and rsh sessions should exist re-initialized periodically. rlogin uses the -f, -F, and -x options in the identical style as the telnet client. The /etc/krb5/krb5.conf file supports the following rlogin options: forward, forwardable, and encrypt.

    Command-line options override configuration file settings. For example, if the rsh section in the krb5.conf file indicates encrypt false, but the -x option is used on the command line, an encrypted session is used.

    rcp

    Kerberized rcp can exist used to transfer files securely between systems using Kerberos authentication and encryption (with the -x command-line option). It does not prompt for passwords, the user must already abide a sound TGT before using rcp if they wish to utilize the encryption feature. However, beware if the -x option is not used and no local credentials are available, the rcp session will revert to the standard, non-Kerberized (and insecure) rcp behavior. It is highly recommended that users always utilize the -x option when using the Kerberized rcp client.The /etc/krb5/krb5.conf file supports the encrypt [true/false] option.

    login

    The Kerberos login program (login.krb5) is forked from a successful authentication by the Kerberized telnet daemon or the Kerberized rlogin daemon. This Kerberos login daemon is sever from the criterion Solaris OE login daemon and thus, the criterion Solaris OE features such as BSM auditing are not yet supported when using this daemon. The /etc/krb5/krb5.conf file supports the krb5_get_tickets [true/false] option. If this option is set to true, then the login program will generate a unique Kerberos ticket (TGT) for the user upon proper authentication.

    ftp

    The Sun Enterprise Authentication Mechanism (SEAM) version of the ftp client uses the GSSAPI (RFC 2743) with Kerberos v5 as the default mechanism. This means that it uses Kerberos authentication and (optionally) encryption through the Kerberos v5 GSS mechanism. The only Kerberos-related command-line options are -f and -m. The -f option is the identical as described above for telnet (there is no exigency for a -F option). -m allows the user to specify an alternative GSS mechanism if so desired, the default is to utilize the kerberos_v5 mechanism.

    The protection plane used for the data transfer can exist set using the protect command at the ftp prompt. Sun Enterprise Authentication Mechanism software ftp supports the following protection levels:

  • Clear unprotected, unencrypted transmission

  • Safe data is integrity protected using cryptographic checksums

  • Private data is transmitted with confidentiality and integrity using encryption

  • It is recommended that users set the protection plane to private for everything data transfers. The ftp client program does not support or reference the krb5.conf file to find any optional parameters. everything ftp client options are passed on the command line. observe the man page for the Kerberized ftp client, ftp(1).

    In summary, adding Kerberos to a network can extend the overall security available to the users and administrators of that network. Remote sessions can exist securely authenticated and encrypted, and shared disks can exist secured and encrypted across the network. In addition, Kerberos allows the database of user and service principals to exist managed securely from any machine which supports the SEAM software Kerberos protocol. SEAM is interoperable with other RFC 1510 compliant Kerberos implementations such as MIT Krb5 and some MS Windows 2000 energetic Directory services. Adopting the practices recommended in this section further secure the SEAM software infrastructure to succor ensure a safer network environment.

    Implementing the Sun ONE Directory Server 5.2 Software and the GSSAPI Mechanism

    This section provides a high-level overview, followed by the in-depth procedures that picture the setup necessary to implement the GSSAPI mechanism and the Sun ONE Directory Server 5.2 software. This implementation assumes a realm of EXAMPLE.COM for this purpose. The following list gives an initial high-level overview of the steps required, with the next section providing the circumstantial information.

  • Setup DNS on the client machine. This is an principal step because Kerberos requires DNS.

  • Install and configure the Sun ONE Directory Server version 5.2 software.

  • Check that the directory server and client both abide the SASL plug-ins installed.

  • Install and configure Kerberos v5.

  • Edit the /etc/krb5/krb5.conf file.

  • Edit the /etc/krb5/kdc.conf file.

  • Edit the /etc/krb5/kadm5.acl file.

  • Move the kerberos_v5 line so it is the first line in the /etc/gss/mech file.

  • Create unique principals using kadmin.local, which is an interactive commandline interface to the Kerberos v5 administration system.

  • Modify the rights for /etc/krb5/krb5.keytab. This access is necessary for the Sun ONE Directory Server 5.2 software.

  • Run /usr/sbin/kinit.

  • Check that you abide a ticket with /usr/bin/klist.

  • Perform an ldapsearch, using the ldapsearch command-line appliance from the Sun ONE Directory Server 5.2 software to test and verify.

  • The sections that ensue fill in the details.

    Configuring a DNS Client

    To exist a DNS client, a machine must elope the resolver. The resolver is neither a daemon nor a lone program. It is a set of dynamic library routines used by applications that exigency to know machine names. The resolver’s office is to resolve users’ queries. To upshot that, it queries a name server, which then returns either the requested information or a referral to another server. Once the resolver is configured, a machine can request DNS service from a name server.

    The following instance shows you how to configure the resolv.conf(4) file in the server kdc1 in the example.com domain.

    ; ; /etc/resolv.conf file for dnsmaster ; domain example.com nameserver 192.168.0.0 nameserver 192.168.0.1

    The first line of the /etc/resolv.conf file lists the domain name in the form:

    domain domainname

    No spaces or tabs are permitted at the conclude of the domain name. do sure that you press recrudesce immediately after the eventual character of the domain name.

    The second line identifies the server itself in the form:

    nameserver IP_address

    Succeeding lines list the IP addresses of one or two slave or cache-only name servers that the resolver should consult to resolve queries. name server entries abide the form:

    nameserver IP_address

    IP_address is the IP address of a slave or cache-only DNS name server. The resolver queries these name servers in the order they are listed until it obtains the information it needs.

    For more circumstantial information of what the resolv.conf file does, refer to the resolv.conf(4) man page.

    To Configure Kerberos v5 (Master KDC)

    In the this procedure, the following configuration parameters are used:

  • Realm name = EXAMPLE.COM

  • DNS domain name = example.com

  • Master KDC = kdc1.example.com

  • admin principal = lucy/admin

  • Online succor URL = http://example:8888/ab2/coll.384.1/SEAM/@AB2PageView/6956

  • This procedure requires that DNS is running.

    Before you open this configuration process, do a backup of the /etc/krb5 files.

  • Become superuser on the master KDC. (kdc1, in this example)

  • Edit the Kerberos configuration file (krb5.conf).

    You exigency to change the realm names and the names of the servers. observe the krb5.conf(4) man page for a replete description of this file.

    kdc1 # more /etc/krb5/krb5.conf [libdefaults] default_realm = EXAMPLE.COM [realms] EXAMPLE.COM = { kdc = kdc1.example.com admin server = kdc1.example.com } [domain_realm] .example.com = EXAMPLE.COM [logging] default = FILE:/var/krb5/kdc.log kdc = FILE:/var/krb5/kdc.log [appdefaults] gkadmin = { help_url = http://example:8888/ab2/coll.384.1/SEAM/@AB2PageView/6956 }

    In this example, the lines for domain_realm, kdc, admin_server, and everything domain_realm entries were changed. In addition, the line with ___slave_kdcs___ in the [realms] section was deleted and the line that defines the help_url was edited.

  • Edit the KDC configuration file (kdc.conf).

    You must change the realm name. observe the kdc.conf( 4) man page for a replete description of this file.

    kdc1 # more /etc/krb5/kdc.conf [kdcdefaults] kdc_ports = 88,750 [realms] EXAMPLE.COM= { profile = /etc/krb5/krb5.conf database_name = /var/krb5/principal admin_keytab = /etc/krb5/kadm5.keytab acl_file = /etc/krb5/kadm5.acl kadmind_port = 749 max_life = 8h 0m 0s max_renewable_life = 7d 0h 0m 0s exigency poignant ---------> default_principal_flags = +preauth }

    In this example, only the realm name definition in the [realms] section is changed.

  • Create the KDC database by using the kdb5_util command.

    The kdb5_util command, which is located in /usr/sbin, creates the KDC database. When used with the -s option, this command creates a stash file that is used to authenticate the KDC to itself before the kadmind and krb5kdc daemons are started.

    kdc1 # /usr/sbin/kdb5_util create -r EXAMPLE.COM -s Initializing database '/var/krb5/principal' for realm 'EXAMPLE.COM' master key name 'K/M@EXAMPLE.COM' You will exist prompted for the database Master Password. It is principal that you NOT FORGET this password. Enter KDC database master key: key Re-enter KDC database master key to verify: key

    The -r option followed by the realm name is not required if the realm name is equivalent to the domain name in the server’s name space.

  • Edit the Kerberos access control list file (kadm5.acl).

    Once populated, the /etc/krb5/kadm5.acl file contains everything principal names that are allowed to administer the KDC. The first entry that is added might behold similar to the following:

    lucy/admin@EXAMPLE.COM *

    This entry gives the lucy/admin principal in the EXAMPLE.COM realm the aptitude to modify principals or policies in the KDC. The default installation includes an asterisk (*) to match everything admin principals. This default could exist a security risk, so it is more secure to comprehend a list of everything of the admin principals. observe the kadm5.acl(4) man page for more information.

  • Edit the /etc/gss/mech file.

    The /etc/gss/mech file contains the GSSAPI based security mechanism names, its object identifier (OID), and a shared library that implements the services for that mechanism under the GSSAPI. Change the following from:

    # Mechanism name object Identifier Shared Library Kernel Module # diffie_hellman_640_0 1.3.6.4.1.42.2.26.2.4 dh640-0.so.1 diffie_hellman_1024_0 1.3.6.4.1.42.2.26.2.5 dh1024-0.so.1 kerberos_v5 1.2.840.113554.1.2.2 gl/mech_krb5.so gl_kmech_krb5

    To the following:

    # Mechanism name object Identifier Shared Library Kernel Module # kerberos_v5 1.2.840.113554.1.2.2 gl/mech_krb5.so gl_kmech_krb5 diffie_hellman_640_0 1.3.6.4.1.42.2.26.2.4 dh640-0.so.1 diffie_hellman_1024_0 1.3.6.4.1.42.2.26.2.5 dh1024-0.so.1
  • Run the kadmin.local command to create principals.

    You can add as many admin principals as you need. But you must add at least one admin principal to complete the KDC configuration process. In the following example, lucy/admin is added as the principal.

    kdc1 # /usr/sbin/kadmin.local kadmin.local: addprinc lucy/admin Enter password for principal "lucy/admin@EXAMPLE.COM": Re-enter password for principal "lucy/admin@EXAMPLE.COM": Principal "lucy/admin@EXAMPLE.COM" created. kadmin.local:
  • Create a keytab file for the kadmind service.

    The following command sequence creates a special keytab file with principal entries for lucy and tom. These principals are needed for the kadmind service. In addition, you can optionally add NFS service principals, host principals, LDAP principals, and so on.

    When the principal instance is a host name, the fully qualified domain name (FQDN) must exist entered in lowercase letters, regardless of the case of the domain name in the /etc/resolv.conf file.

    kadmin.local: ktadd -k /etc/krb5/kadm5.keytab kadmin/kdc1.example.com Entry for principal kadmin/kdc1.example.com with kvno 3, encryption sort DES-CBC-CRC added to keytab WRFILE:/etc/krb5/kadm5.keytab. kadmin.local: ktadd -k /etc/krb5/kadm5.keytab changepw/kdc1.example.com Entry for principal changepw/kdc1.example.com with kvno 3, encryption sort DES-CBC-CRC added to keytab WRFILE:/etc/krb5/kadm5.keytab. kadmin.local:

    Once you abide added everything of the required principals, you can exit from kadmin.local as follows:

    kadmin.local: quit
  • Start the Kerberos daemons as shown:

    kdc1 # /etc/init.d/kdc start kdc1 # /etc/init.d/kdc.master start

    Note

    You quit the Kerberos daemons by running the following commands:

    kdc1 # /etc/init.d/kdc stop kdc1 # /etc/init.d/kdc.master stop
  • Add principals by using the SEAM Administration Tool.

    To upshot this, you must log on with one of the admin principal names that you created earlier in this procedure. However, the following command-line instance is shown for simplicity.

    kdc1 # /usr/sbin/kadmin -p lucy/admin Enter password: kws_admin_password kadmin:
  • Create the master KDC host principal which is used by Kerberized applications such as klist and kprop.

    kadmin: addprinc -randkey host/kdc1.example.com Principal "host/kdc1.example.com@EXAMPLE.COM" created. kadmin:
  • (Optional) Create the master KDC root principal which is used for authenticated NFS mounting.

    kadmin: addprinc root/kdc1.example.com Enter password for principal root/kdc1.example.com@EXAMPLE.COM: password Re-enter password for principal root/kdc1.example.com@EXAMPLE.COM: password Principal "root/kdc1.example.com@EXAMPLE.COM" created. kadmin:
  • Add the master KDC’s host principal to the master KDC’s keytab file which allows this principal to exist used automatically.

    kadmin: ktadd host/kdc1.example.com kadmin: Entry for principal host/kdc1.example.com with ->kvno 3, encryption sort DES-CBC-CRC added to keytab ->WRFILE:/etc/krb5/krb5.keytab kadmin:

    Once you abide added everything of the required principals, you can exit from kadmin as follows:

    kadmin: quit
  • Run the kinit command to obtain and cache an initial ticket-granting ticket (credential) for the principal.

    This ticket is used for authentication by the Kerberos v5 system. kinit only needs to exist elope by the client at this time. If the Sun ONE directory server were a Kerberos client also, this step would exigency to exist done for the server. However, you may want to utilize this to verify that Kerberos is up and running.

    kdclient # /usr/bin/kinit root/kdclient.example.com Password for root/kdclient.example.com@EXAMPLE.COM: passwd
  • Check and verify that you abide a ticket with the klist command.

    The klist command reports if there is a keytab file and displays the principals. If the results betray that there is no keytab file or that there is no NFS service principal, you exigency to verify the completion of everything of the previous steps.

    # klist -k Keytab name: FILE:/etc/krb5/krb5.keytab KVNO Principal ---- ------------------------------------------------------------------ 3 nfs/host.example.com@EXAMPLE.COM

    The instance given here assumes a lone domain. The KDC may reside on the identical machine as the Sun ONE directory server for testing purposes, but there are security considerations to engage into account on where the KDCs reside.

  • With regards to the configuration of Kerberos v5 in conjunction with the Sun ONE Directory Server 5.2 software, you are finished with the Kerberos v5 part. It’s now time to behold at what is required to exist configured on the Sun ONE directory server side.

    Sun ONE Directory Server 5.2 GSSAPI Configuration

    As previously discussed, the Generic Security Services Application Program Interface (GSSAPI), is criterion interface that enables you to utilize a security mechanism such as Kerberos v5 to authenticate clients. The server uses the GSSAPI to actually validate the identity of a particular user. Once this user is validated, it’s up to the SASL mechanism to apply the GSSAPI mapping rules to obtain a DN that is the bind DN for everything operations during the connection.

    The first item discussed is the unique identity mapping functionality.

    The identity mapping service is required to map the credentials of another protocol, such as SASL DIGEST-MD5 and GSSAPI to a DN in the directory server. As you will observe in the following example, the identity mapping feature uses the entries in the cn=identity mapping, cn=config configuration branch, whereby each protocol is defined and whereby each protocol must discharge the identity mapping. For more information on the identity mapping feature, refer to the Sun ONE Directory Server 5.2 Documents.

    To discharge the GSSAPI Configuration for the Sun ONE Directory Server Software
  • Check and verify, by retrieving the rootDSE entry, that the GSSAPI is returned as one of the supported SASL Mechanisms.

    Example of using ldapsearch to retrieve the rootDSE and rep the supported SASL mechanisms:

    $./ldapsearch -h directoryserver_hostname -p ldap_port -b "" -s ground "(objectclass=*)" supportedSASLMechanisms supportedSASLMechanisms=EXTERNAL supportedSASLMechanisms=GSSAPI supportedSASLMechanisms=DIGEST-MD5
  • Verify that the GSSAPI mechanism is enabled.

    By default, the GSSAPI mechanism is enabled.

    Example of using ldapsearch to verify that the GSSAPI SASL mechanism is enabled:

    $./ldapsearch -h directoryserver_hostname -p ldap_port -D"cn=Directory Manager" -w password -b "cn=SASL, cn=security,cn= config" "(objectclass=*)" # # Should return # cn=SASL, cn=security, cn=config objectClass=top objectClass=nsContainer objectClass=dsSaslConfig cn=SASL dsSaslPluginsPath=/var/Sun/mps/lib/sasl dsSaslPluginsEnable=DIGEST-MD5 dsSaslPluginsEnable=GSSAPI
  • Create and add the GSSAPI identity-mapping.ldif.

    Add the LDIF shown below to the Sun ONE Directory Server so that it contains the remedy suffix for your directory server.

    You exigency to upshot this because by default, no GSSAPI mappings are defined in the Sun ONE Directory Server 5.2 software.

    Example of a GSSAPI identity mapping LDIF file:

    # dn: cn=GSSAPI,cn=identity mapping,cn=config objectclass: nsContainer objectclass: top cn: GSSAPI dn: cn=default,cn=GSSAPI,cn=identity mapping,cn=config objectclass: dsIdentityMapping objectclass: nsContainer objectclass: top cn: default dsMappedDN: uid=${Principal},ou=people,dc=example,dc=com dn: cn=same_realm,cn=GSSAPI,cn=identity mapping,cn=config objectclass: dsIdentityMapping objectclass: dsPatternMatching objectclass: nsContainer objectclass: top cn: same_realm dsMatching-pattern: ${Principal} dsMatching-regexp: (.*)@example.com dsMappedDN: uid=$1,ou=people,dc=example,dc=com

    It is principal to do utilize of the ${Principal} variable, because it is the only input you abide from SASL in the case of GSSAPI. Either you exigency to build a dn using the ${Principal} variable or you exigency to discharge pattern matching to observe if you can apply a particular mapping. A principal corresponds to the identity of a user in Kerberos.

    You can find an instance GSSAPI LDIF mappings files in ServerRoot/slapdserver/ldif/identityMapping_Examples.ldif.

    The following is an instance using ldapmodify to upshot this:

    $./ldapmodify -a -c -h directoryserver_hostname -p ldap_port -D "cn=Directory Manager" -w password -f identity-mapping.ldif -e /var/tmp/ldif.rejects 2> /var/tmp/ldapmodify.log
  • Perform a test using ldapsearch.

    To discharge this test, sort the following ldapsearch command as shown below, and acknowledge the prompt with the kinit value you previously defined.

    Example of using ldapsearch to test the GSSAPI mechanism:

    $./ldapsearch -h directoryserver_hostname -p ldap_port -o mech=GSSAPI -o authzid="root/hostname.domainname@EXAMPLE.COM" -b "" -s ground "(objectclass=*)"

    Microsoft Studio – a masterpiece (review) | killexams.com existent questions and Pass4sure dumps

    There is instant treasure — a wow instant — for this device for those who observe it for the first time. Then the cardinal sins of lust, jealousy, greed, and envy set in followed by wrath when I declare them the price. Seriously, this is the stuff electric dreams are made of if you abide abysmal pockets.

    To exist transparent – there is no other all-in-one computing device relish the Microsoft Studio on the planet and it sets the bar almost impossibly high as a creative appliance and oh, yes, it’s a computing device too but let’s not sully it running spreadsheets! quit press – Dell will exist soon introducing its engage on the Studio.

    MS Studio screen tilt

    To exist technical it is a Surface styled, all-in-one (A-I-O import everything is built into the screen/stand), Intel Core i5 or i7 computer, NVIDIA GeForce GPU, up to 32GB RAM, with a 28”, 4500 x 3000, impossibly thin, touch/pen screen mounted on a zero-gravity hinge for a floating pomp that can act as a desktop, or a slightly inclined table top device. Add to that the Surface Dial, Pen, Keyboard and Mouse and you abide the most desirable PC on earth.

    OK, I will qualify that eventual statement. This is not really designed as an “office PC” and to utilize it as such would simply exist to satisfy a desire to own the best – a bit relish owning a Lambo, Porsche, Maserati, Bugatti … and then only being able to drive it on congested Sydney Streets. Bragging rights – ego is not a dirty word in this case.

    This is really designed for the creative factor who may abide been perfectly elated with Macs and Wacom Cintiq and did not realise how seductive touch, pen, and the dial interfaces — everything on the one workspace device — can be. Once you abide tried it, you are unlikely to gallop back.

    Out of the box – Microsoft Studio

    Let’s start with the box – it is quite beautiful. You lay it down flat, release the two tabs and it opens clamshell-style to betray the huge screen. The instructions declare you to gently rear the screen out (and with it the base) and situation it on a desk. Plug in the power cable. unbox the keyboard, mouse and pen (Dial sold separately) and on inserting the batteries Bluetooth pairing begins – its ready to go. Absolute simplicity.

    Set-up is typical Windows 10 Creator Edition (only released in mid-April) – asking permission, and advising you on security settings (yes, you can swirl everything options off without issue), a Microsoft account (you can utilize a local sign-in avoiding the account) and up comes this most lovely 10-bit colour screen with 13.5 million pixels. This is the best screen I abide seen on any large LED/LCD device – its colours are as good, if not better than the previous class leader Microsoft Surface Book.

    Lust, jealousy, greed, envy – I want one, I just do. Alas, it goes back to Microsoft after they prise it from my cold, dead, hands …

    Elephants in the room

    Before they rep into the review let's address issues that abide been mentioned by some commentators.

    It uses a 6th generation Intel Skylake Core i5-6440HQ (2.6/3.5GHz, 6MB cache) or i7-6820HQ (2.7/3.6GHz, 8MB cache) mobile processor. These abide a 45-Watt TPD needed for the enclosed A-I-O base.

    The facts are that the 7th generation Kaby Lake processors focus on power management rather than raw horsepower. Sure, the latter would abide been nice but you don’t buy a supercar based on the year of its engine design – nor should you deduct any points here because these CPUs will wield typical design or CAD work you hurl at them.

    It uses a NVIDIA GeForce GTX 965M GPU with 2GB GB GDDR5 in the ground i5 and i7 units or the GTX 980M with 4GB GDDR5 memory on the top specified unit. Ditto – there may exist newer versions of these mobile CPUs but there is a tonne of power for graphics, rendering, design, photo editing and more.

    The is no USB-C or Thunderbolt 3 port. No, it is not a notebook – it is a fully-fledged A-I-O desktop with four full-sized USB-A 3.0 ports, an SD card reader, Mini-Display port (for an extra monitor), Gigabit Ethernet and 3.5mm combo audio jack. Still, a Thunderbolt 3 port would abide been nice for expansion on a device that will eventual several years.

    Hybrid drives (SSD and spinning disk combo) tender improved accelerate over spinning disks and higher capacities over SSD. I suspect that future updates will observe this gallop to PCIe NVMe SSD when the capacity criteria is reached. Still, the hybrid drive performs very well and it is replaceable/upgradable.

    Finally, is the price and if market response is anything to gallop by – it is well priced for creative types. Don’t try and compare it to a desktop or gaming PC, but more a MacBook Pro and Wacom Cintiq 27QHD.

    The ground unit is an i5, 8GB, GTX 965, 1TB (Rapid Hybrid) at $4699.

    The next up is an i7, 16GB, GTX 965, 1TB (Rapid Hybrid) at $5499.

    Top of the range is an i7, 32GB, GTX 980, 2TB (Rapid Hybrid) at $6599.

    The pomp – the stunning 4.5K pomp is just 12.5 mm thick

    It is 28.125”, 4500x3000, 13.5 million pixels, 3:2 ratio, 192ppi, PixelSense pomp with 10-point multi-touch and pen support covered in Gorilla Glass (unspecified). It has 63% more pixels than a 4K display.

    MS Studio screen back

    What Microsoft doesn't declare you is that PixelSense is driven by a sever Atmel ATSAMS70N21, 32-bit ARM Cortex-M7 processor – that is, in addition to the NVIDIA GPU that would normally wield this work. Its main job is to ensure the individual factory colour calibrated pomp can cover Adobe sRGB, DCI-P3 and Vivid Colour Profiles. This is the first known utilize of a co-processor just to wield PixelSense (or whatever anyone else calls it).

    The 3:2 ratio has now become accepted as the faultless creative ratio allowing 50 square inches (32,258 square mm) more pomp than a 27-inch 16:9 display. It has 17% more screen space than a 27” iMac.

    sRGB is the most commonly used colour mode – let’s muster it realistic to the extent that inkjet and laser printers utilize the standard. Surface Studio achieves 100% sRGB – faultless for a desktop monitor.

    Cinematographers will exist familiar with DCI-P3 – it is what movies shoot for. Unless you are a video professional you probably won’t utilize this mode.

    Finally, there is Vivid mode – and it is a blend of modes (P3 D65) to more accurately reflect existent life colours. Most will utilize this as the default viewing mode.

    Contrast is well over what is expected of professionally calibrated larger LED/LCD screens – 1040:1 and it is manifested by images that jump out at you. Brightness is 421 cd/m2 and what that means is typically you will view it at about 50% brightness. Saturation accuracy is as beneficial as the Surface reserve and Pro 4.

    The 12.5mm thick screen is mounted on a zero-gravity hinge to the base. One finger is everything you exigency to gallop it from desktop to tabletop mode (20° angle) – or anywhere in between.

    In tabletop mode, it will noiseless proper on a 600mm abysmal desktop with latitude for the Bluetooth keyboard in front. That is principal as you exigency to abide the screen proximate to you – leaning over and into it to utilize it as a creative tableau – just relish a drafting board. I spent hours doodling, colouring and drawing and never felt fatigue. It is also the faultless device to accompany a “standing” desk.

    It has one minor irritation – the expansion ports are everything on the rear of the stand and it is a slight difficult to rep to them to insert a USB etc.

    The screen is not the fingerprint magnet I thought it would exist – an oleophobic coating minimises that, but rep a micro fibre screen cleaner cloth anyway.

    Microsoft has done an wonderful job on this screen – there should exist no complaints from professional users.

    P.S. – as a doctor friend pointed out it can also exist used as a light box/table with pure white light to betray X-Rays, slides etc.

    Performance

    The review unit is an i7-6820HQ mobile, four-core, eight-thread processor whereas the Studio reserve uses the i7-6600U mobile processor. PC ticket 8 has these at 3774 and 2995 respectively. What that means is that it will discharge as well as any other using the identical processor.

    It handles most tasks with ease and has power for CAD/CAM/rendering but recollect it is essentially a mobile processor. if you were going to upshot a lot of this you probably would exist using a multiprocessor Xeon workstation, with a couple of 27” monitors.

    What was impressive was that at idle it barely registered on the CPU (<1%) and memory usage was 10% - Microsoft has done an wonderful job in turning Windows to this – as it should.

    Video performance – no issues replaying 4K video @30fps. Games performance – no issues at HD @60fps.

    The 2TB Seagate-Samsung, SpinPoint M9T, ST200LM003, 2.5”, 5400RPM, SATA 6.0Gbps drive uses a sever 32MB DDR cache enabling microsecond read/write for data in the cache. This is paired with a 64GB SATA SSD (i5) and 128GB PCIe NVME SSD (i7) and uses Intel Rapid Storage Technology to manage the two drives as if they were one.

    I got over 200Mb/s read and 100Mb/s write poignant 3-4MB photos around. As PCIe NVME SSD drives reduce in cost and extend in capacity await later Studios to utilize pure SSD. At least here you can supersede or extend the spinning disk if you wish.

    Wi-Fi AC uses the identical Marvel AVASTAR AC controller as the Surface Book. While adequate this controller varies in accelerate from 234 to 468Mbps (hooked up to a D-Link DLR-895 AC5300 router) compared to the unique Dell XPS 13 using the Killer AC chipset and obtaining 866.7Mbps. My recommendation is to utilize the Gigabit Ethernet hard-wired connection if you plot to gallop stout files.

    Bluetooth Keyboard, Mouse and Pen

    When I first saw the keyboard I was a slight surprised – it was tiny and elegant relish a Mac, not at everything relish the habitual PC mechanical key-switch thumper keyboards I utilize as a writer. But after a while I realised it is the desktop version of the excellent chiclet keyboard on the Surface Book, perhaps with an even better feel and tactile feedback.

    It has a sever left/right/up/down arrow section – Great as I disapprove compact keyboards where these are tucked under the enter key. It has dedicated page up, page down, home and conclude keys – Great as I disapprove it when you exigency to access these by a pressing a Fn button as well. I wrote this review on it so it is pretty good. Battery life from two AAAs is about a year.

    The mouse looks modern, minimalist, and perhaps a slight uninspiring – not relish the edgy Arc Mouse Microsoft makes. But it performs very well, its blue light laser works on transparent and coloured glass desks, and it has precise wheel placement.

    The Surface Pen is the identical as on the reserve and Pro. It is an N-Trig device and supports 1024 levels of pressure. The Pen “app” allows easy customisation. The Pro 4 and reserve nailed writing on glass making it very similar in feel to pen and paper – you can feel a slight reassuring drag as you draw on glass. I treasure the ruler feature to draw straight lines and situation shapes.

    There is a unique Surface Pen coming with 4096 pressure levels – artists will want this

    Dial (optional $149.95)

    I am not equipped to review the dial in the identical manner as a professional artist, designer, CAD architect or draftsman would so my review is more about what the Dial can do. Let me simply declare I did not know how useful it could exist until I used it.

    MS Studio dial

    The Bluetooth Dial, really a companion to the Pen, is a unique way to interact with the screen and what you are doing (context). It brings a raft of context-sensitive commands to your fingertips. It can exist used on the unique Surface Pro and soon, via a firmware update, the Surface Pro 4 and Book.

    Essentially you press the puck down and it displays a radial menu of things you can select – that might exist colour gamut, pen colour, thickness, style, or even to magnify, resize, rotate and orient images. It is a natural in 3D images where you can utilize it to gad around the image. In music it can adjust volume, quit and start play.

    Dial uses haptic feedback to succor you understand your actions are completed. Its SDK (software design kit) is freely available to developers so you will observe more apps support dial – recollect it is about bringing commands, actions to your fingertips instead of opening an app.

    Importantly Dial does not exigency to exist on the screen itself to exist used and I organize it easier to utilize placed near the mouse.

    Initial apps comprehend Sketchable, Mental Canvas, Drawboard PDF, MOHO 12, StaffPad (music), and BlueBeam Revu (plan/PDF mark-up). Most of the Adobe Creative Cloud apps also support it.

    It works with Microsoft apps including Office, Groove, Maps, Edge and more. Se the updated list here.

    Audio/Camera/Mic

    Seven speakers — four downwards firing under the screen, two in the ground and a subwoofer — do this an pattern movie device outputting 88dB. It provides 2.1 (L+R+subwoofer) Dolby Audio (capable) sound.

    Its sound is the best of any A-I-O I abide seen, able to fill a reasonably sized latitude (say 5 x 5m) with crisp, clear, sound and surprisingly beneficial bass from the subwoofer.

    THD (total harmonic distortion) appears low even at replete volume. It is hard to give it a sound signature – beneficial but recessed bass, beneficial mid-range and beneficial treble so it is more of a “Bright Vocal” which makes sense, providing clarity of speech for movies and Skype.

    I could not find an equaliser app on the device nor in the Windows Store – Realtek high Definition Audio offers almost no EQ control. It does abide NVIDIA HDMI sound output over the mini-DisplayPort to HDMI port.

    The front-facing IR, 3D, Windows Hello enabled camera is likeaflash and accurate. I can’t succor fire there is more potential for this device in scanning 3D objects etc.

    The unit has two fans that for the most piece are very quiet. After some ponderous work, you could just notice the gentle whir.

    Pros:

  • Dead sexy device – elicits most of the seven cardinal sin emotions
  • Amazing screen with low reflectivity and the best colour attribute of any 28” monitor I abide seen
  • 3:2 ratio and 200% scaling is flawless for creative and office work
  • Three different colour presets
  • All-in-one shape factor
  • Good sound attribute and volume – could utilize an equaliser
  • The best build quality, zero-gravity hinge for ease of movement
  • Cons:

  • Rear ports do it harder to slip USB drives in and out.
  • Not upgradable apart from the hard disk – but that shape factor seldom is.
  • Would abide preferred an everything SSD option, perhaps Intel Optane, but the Hybrid is not a deal breaker.
  • Some may wait for the refresh in a year for later CPU and GPU tech but this is not a deal breaker – it is just not as future proof as the cost indicates.
  • Summary

    As an “objet d'art” it is lovely – a masterpiece that da Vinci could not better on. You can desire this. Everyone who I abide introduced it to has said, “I can’t believe I treasure a Windows computer.” As Satya Nadella said, “We want to gallop from people needing Windows, to choosing Windows, to loving Windows.” This and the rest of the Surface range really helps bragging rights.

    As a computer, it is a powerful i5/i7 device capable of pleasing everything bar extreme power users. And that includes things relish the immensely CPU-hungry Adobe Lightroom.

    To a Mac or Wacom Cintiq user — it is OK to covet it, even compliment Microsoft on it, but you won’t change secretly swearing that you wish Apple would gallop handle on a Mac, rep a Pen for a Mac, and that Dial — it is something else too (Yes, I know you utilize a MacBook, Wacom Cintiq 27QHD, etc., and probably spent $4K more than the Studio costs).

    As a creative tool, there is nothing relish the Surface Dial and N-Trig pen on a 28” screen.

    Yet this is version one – there is so much more scope for Studio 2, 3, 4 and steroid versions in the future that will address even the most hungry power users. And it won’t exist long before Dell, Acer, Asus, HP and Lenovo pick up the Studio challenge – the Windows open OEM ecosystem is a wonderful thing.

    Just to betray that this review is objective abide a read of the Reddit thread titled “Not one faultfinding review of Microsoft Studio”

    Rating: For what it is today with everything its elephants – 4.5 out of 5. For what it heralds/portends 15 out of 10.
