The requirements were developed from DoD consensus, as well as the Windows 2008 Security Guide and security templates published by Microsoft Corporation. Comments or proposed revisions to this document should be sent via e-mail to the following address: [email protected]
Vuln Rule Version CCI Severity Title Description
SV-29338r2_rule 2.005 CCI-000366 HIGH Systems must be at supported service packs (SP) or releases levels. Systems at unsupported service packs or releases will not receive security updates for new vulnerabilities and leaves them subject to exploitation. Systems must be maintained at a service pack level supported by the vendor with new security updates.HKSystem Administrator
SV-29591r1_rule 3.007 CCI-000366 LOW The system allows shutdown from the logon dialog box. Displaying the shutdown button may allow individuals to shut down a system anonymously. Only authenticated users should be allowed to shut down the system. Preventing display of this button in the logon dialog box, ensures that individuals who shut down the system are authorized and tracked in the systems Security event log.HKSystem Administrator
SV-29478r1_rule 2.008 CCI-000213 HIGH Local volumes are not formatted using NTFS. This is a category 1 finding because the ability to set access permissions and audit critical directories and files is only available by using the NTFS file system. The capability to assign access permissions to file objects is a DOD policy requirement. The FAT file system only provides the capability to make files read-only and hidden. The capability to change these attributes is not restricted to any users. An unauthorized individual could boot the machine from a floppy disk and gain full and unrecorded access to file data. trueSystem AdministratorInformation Assurance Officer
SV-29634r4_rule 3.011 CCI-000048 MEDIUM The required legal notice must be configured to display before console logon. Failure to display the logon banner prior to a logon attempt will negate legal proceedings resulting from unauthorized access to system resources.System AdministratorInformation Assurance Officer
SV-28979r3_rule 3.013 CCI-000366 LOW Caching of logon credentials must be limited. The default Windows configuration caches the last logon credentials for users who log on interactively to a system. This feature is provided for system availability reasons, such as the user's machine being disconnected from the network or domain controllers being unavailable. Even though the credential cache is well-protected, if a system is attacked, an unauthorized individual may isolate the password to a domain user account using a password-cracking program and gain access to the domain.HKSystem Administrator
SV-28983r1_rule 3.018 CCI-001090 HIGH Anonymous shares are not restricted. This is a Category 1 finding because it allows anonymous logon users (null session connections) to list all account names and enumerate all shared resources, thus providing a map of potential points to attack the system.trueIn a mixed Windows environment this setting may cause systems with down-level operating systems to fail to authenticate, may prevent their users from changing their passwords, and may cause problems with managing printers and spools. In domains supporting Exchange 2003 servers and versions of Outlook earlier than Outlook 2003, the setting “Network access: Do not allow anonymous enumeration of SAM accounts and shares” should be set to “Disabled” on the Domain Controller Group Policy, to allow Outlook to anonymously query the global catalog service.System AdministratorInformation Assurance Officer
SV-28987r1_rule 4.002 CCI-000044 MEDIUM Number of allowed bad-logon attempts does not meet minimum requirements. The account lockout feature, when enabled, prevents brute-force password attacks on the system. The higher this value is, the less effective the account lockout feature will be in protecting the local system. The number of bad logon attempts should be reasonably small to minimize the possibility of a successful password attack, while allowing for honest errors made during a normal user logon.HKSystem Administrator
SV-29639r2_rule 4.003 CCI-000044 MEDIUM The reset period for the account lockout counter must be configured to 15 minutes or greater on Windows 2008. The account lockout feature, when enabled, prevents brute-force password attacks on the system. This parameter specifies the period of time that must pass after failed logon attempts before the counter is reset to "0". The smaller this value is, the less effective the account lockout feature will be in protecting the local system.HKSystem Administrator
SV-29643r2_rule 4.004 CCI-002238 MEDIUM Windows 2008 account lockout duration must be configured to 15 minutes or greater. The account lockout feature, when enabled, prevents brute-force password attacks on the system. This parameter specifies the period of time that an account will remain locked after the specified number of failed logon attempts.HKSystem Administrator
SV-28991r1_rule 4.009 CCI-002235 HIGH Unauthorized users are granted right to Act as part of the operating system. This is a Category 1 finding because users and user groups that are assigned this right can bypass all security protective mechanisms that apply to all users, including administrators. Accounts with this right should have passwords with the maximum length and be kept in a locked container accessible only by the IAO and his designated backup. Some applications require this right to function. Any exception needs to be documented with the IAO.trueRemoving application accounts from this right may cause the applications to stop functioning.System AdministratorInformation Assurance Officer
SV-18394r4_rule 4.010-DC CCI-000366 MEDIUM User rights assignments must meet minimum requirements. Inappropriate granting of user rights can provide system, administrative, and other high level capabilities not required by the normal user.trueSystem AdministratorInformation Assurance Officer
SV-29647r1_rule 4.011 CCI-000199 MEDIUM Maximum password age does not meet minimum requirements. The longer a password is in use, the greater the opportunity for someone to gain unauthorized knowledge of the passwords. Further, scheduled changing of passwords hinders the ability of unauthorized system users to crack passwords and gain access to a system.HKSystem Administrator
SV-28995r1_rule 4.012 CCI-000198 MEDIUM Minimum password age does not meet minimum requirements. Permitting passwords to be changed in immediate succession within the same day, allows users to cycle passwords through their history database. This enables users to effectively negate the purpose of mandating periodic password changes.HKSystem Administrator
SV-29652r2_rule 4.014 CCI-000200 MEDIUM The password history must be configured to 24 passwords remembered. A system is more vulnerable to unauthorized access when system users recycle the same password several times without being required to change a password to a unique password on a regularly scheduled basis. This enables users to effectively negate the purpose of mandating periodic password changes. The default value is 24 for Windows domain systems. DoD has decided this is the appropriate value for all Windows systems.HKSystem Administrator
SV-29657r1_rule 4.020 CCI-000804 MEDIUM The built-in guest account is not disabled. A system faces an increased vulnerability threat if the built-in guest account is not disabled. This account is a known account that exists on all Windows systems and cannot be deleted. This account is initialized during the installation of the operating system with no password assigned. This account is a member of the Everyone user group and has all the rights and permissions associated with that group, which could subsequently provide access to system resources to anonymous users.System Administrator
SV-29485r1_rule 4.021 CCI-000366 MEDIUM The built-in guest account has not been renamed. A system faces an increased vulnerability threat if the built-in guest account is not renamed or disabled. The built-in guest account is a known user account on all Windows systems, and as initially installed, does not require a password. This can allow access to system resources by unauthorized users. This account is a member of the group Everyone and has all the rights and permissions associated with that group and could provide access to system resources to unauthorized users.System Administrator
SV-28998r1_rule 4.022 CCI-000366 MEDIUM The built-in administrator account has not been renamed. The built-in administrator account is a well known account. Renaming the account to an unidentified name improves the protection of this account and the system.System Administrator
SV-29488r2_rule 5.002 CCI-001849 MEDIUM Windows event log sizes must meet minimum requirements. Inadequate log size will cause the log to fill up quickly. This may prevent audit events from being recorded properly and require frequent attention by administrative personnel.System AdministratorInformation Assurance Officer
SV-29507r1_rule 2.006 CCI-002165 MEDIUM ACLs for system files and directories do not conform to minimum requirements. Failure to properly configure file and directory permissions (ACLs) allows the possibility of unauthorized and anonymous modification to the operating system and installed applications.If a manual check of a questionable ACL setting shows that it has been set to meet or is more restrictive than minimum requirements, then it will not be counted as a finding.trueSystem Administrator
SV-29001r2_rule 4.006 CCI-001133 LOW Users must be forcibly disconnected when their logon hours expire. Users must not be permitted to remain logged on to the network after they have exceeded their permitted logon hours. In many cases, this indicates that a user forgot to log off before leaving for the day. However, it may also indicate that a user is attempting unauthorized access at a time when the system may be less closely monitored. Forcibly disconnecting users when logon hours expire protects critical and sensitive network data from exposure to unauthorized personnel with physical access to the computer.HKSystem Administrator
SV-29004r2_rule 3.034 CCI-000197 MEDIUM Unencrypted passwords must not be sent to third-party SMB Servers. Some non-Microsoft SMB servers only support unencrypted (plain text) password authentication. Sending plain text passwords across the network, when authenticating to an SMB server, reduces the overall security of the environment. Check with the Vendor of the SMB server to see if there is a way to support encrypted password authentication.HKSystem Administrator
SV-29007r2_rule 3.040 CCI-000366 MEDIUM Automatic logons must be disabled. Allowing a system to automatically log on when the machine is booted could give access to any unauthorized individual who restarts the computer. Automatic logon with administrator privileges would give full access to an unauthorized individual.If the DefaultName or DefaultDomainName in the same registry path contain an administrator account name and the DefaultPassword contains a value, this is a CAT I finding.System Administrator
SV-29685r2_rule 3.028 CCI-000192 MEDIUM The built-in Windows password complexity policy must be enabled. The use of complex passwords increases their strength against attack. The built-in Windows password complexity policy requires passwords to contain at least 3 of the 4 types of characters (numbers, upper- and lower-case letters, and special characters), as well as preventing the inclusion of user names or parts of.System Administrator
SV-29010r1_rule 3.029 CCI-001812 LOW Print driver installation privilege is not restricted to administrators. By default, the print spooler allows any user to add and to delete printer drivers on the local system. This capability should be restricted to authorized personnel.trueSystem AdministratorInformation Assurance Officer
SV-29595r3_rule 3.030 CCI-002235 HIGH Anonymous access to the registry must be restricted. The registry is integral to the function, security, and stability of the Windows system. Some processes may require anonymous access to the registry. This must be limited to properly protect the system.trueSystem AdministratorInformation Assurance Officer
SV-29013r1_rule 3.031 CCI-000366 HIGH The Send download LanMan compatible password option is not set to Send NTLMv2 response only\refuse LM. The Kerberos v5 authentication protocol is the default for authentication of users who are logging on to domain accounts. NTLM is retained in later Windows versions for compatibility with clients and servers that are running earlier versions of Windows. It is also used to authenticate logons to stand-alone computers that are running later versions.trueSetting this to the required setting may prevent authentication with older Operating Systems and break some applications.System AdministratorInformation Assurance Officer
SV-29016r1_rule 3.032 CCI-000366 MEDIUM Ctrl+Alt+Del security attention sequence is Disabled. Disabling the Ctrl+Alt+Del security attention sequence can compromise system security. Because only Windows responds to the Ctrl+Alt+Del security sequence, you can be assured that any passwords you enter following that sequence are sent only to Windows. If you eliminate the sequence requirement, malicious programs can request and receive your Windows password. Disabling this sequence also suppresses a custom logon banner.HKSystem Administrator
SV-47871r1_rule WINUR-000017-DC CCI-000213 MEDIUM The Deny access to this computer from the network user right on domain controllers must be configured to prevent unauthenticated access. Inappropriate granting of user rights can provide system, administrative, and other high level capabilities. The "Deny Access from the Network" right defines the accounts that are prevented from logging on from the network. The Guests group must be assigned this right to prevent unauthenticated access.trueSystem Administrator
SV-28472r1_rule 3.047 CCI-000366 MEDIUM The Smart Card removal option is set to take no action. Determines what should happen when the smart card for a logged-on user is removed from the smart card reader. The options are: - No Action - Lock Workstation - Force LogofftrueHKSystem Administrator
SV-29027r1_rule 3.046 CCI-002418 MEDIUM The Windows SMB server is not enabled to perform SMB packet signing when possible. If this policy is enabled, it causes the Windows Server Message Block (SMB) server to perform SMB packet signing.HKSystem Administrator
SV-29515r1_rule 3.043 CCI-002418 MEDIUM Outgoing secure channel traffic is not encrypted when possible. Requests sent on the secure channel are authenticated, and sensitive information (such as passwords) is encrypted, but not all information is encrypted. If this policy is enabled, outgoing secure channel traffic should be encrypted.If the value for “Domain Member: Digitally encrypt or sign secure channel data (always)” is set to “Enabled”, then this would not be a finding. HKSystem Administrator
SV-29518r1_rule 3.042 CCI-002418 MEDIUM Outgoing secure channel traffic is not signed when possible. Requests sent on the secure channel are authenticated, and sensitive information (such as passwords) is encrypted, but the channel is not integrity checked. If this policy is enabled, all outgoing secure channel traffic should be signed.If the value for “Domain Member: Digitally encrypt or sign secure channel data (always)” is set to “Enabled”, then this would not be a finding.HKSystem Administrator
SV-29030r1_rule 3.044 CCI-000366 LOW The computer account password is prevented from being reset. As a part of Windows security, computer account passwords are changed automatically. Enabling this policy to disable automatic password changes can make the system more vulnerable to malicious access. Frequent password changes can be a significant safeguard for your system. If this policy is disabled, a new password for the computer account will be generated every week.HKSystem Administrator
SV-29033r1_rule 3.045 CCI-002418 MEDIUM The Windows SMB client is not enabled to perform SMB packet signing when possible. If this policy is enabled, it causes the Windows Server Message Block (SMB) client to perform SMB packet signing when communicating with an SMB server that is enabled or required to perform SMB packet signing.HKSystem Administrator
SV-29217r1_rule 3.052 CCI-000366 MEDIUM Ejection of removable NTFS media is not restricted to Administrators. Removable hard drives can be formatted and ejected by others who are not members of the Administrators Group, if they are not properly configured. Formatting and ejecting removable NTFS media should only be done by administrators.HKSystem Administrator
SV-29220r1_rule 3.054 CCI-000366 LOW Users are not warned in advance that their passwords will expire. This setting configures the system to display a warning to users telling them how many days are left before their password expires. By giving the user advanced warning, the user has time to construct a sufficiently strong password.HKSystem Administrator
SV-29223r1_rule 3.055 CCI-000366 LOW The default permissions of Global system objects are not increased. Windows system maintains a global list of shared system resources such as DOS device names, mutexes, and semaphores. Each type of object is created with a default DACL that specifies who can access the objects with what permissions. If this policy is enabled, the default DACL is stronger, allowing non-admin users to read shared objects, but not modify shared objects that they did not create.HKSystem Administrator
SV-29226r2_rule 4.028 CCI-001133 LOW The amount of idle time required before suspending a session must be properly set. Open sessions can increase the avenues of attack on a system. This setting is used to control when a computer disconnects an inactive SMB session. If client activity resumes, the session is automatically re-established. This protects critical and sensitive network data from exposure to unauthorized personnel with physical access to the computer.HKSystem Administrator
SV-29689r1_rule 3.057 CCI-000196 MEDIUM Reversible password encryption is not disabled. Storing passwords using reversible encryption is essentially the same as storing clear-text versions of the passwords. For this reason, this policy should never be enabled.System Administrator
SV-28493r1_rule AD.3058_2008 CCI-002235 MEDIUM The Server Operators group must have the ability to schedule jobs by means of the AT command disabled. This policy controls the ability of members of the local Server Operators group to schedule AT jobs. If disabled, only administrators can schedule jobs that use AT commands. Unlike Scheduled Tasks which require you to specify the credential under which the task will run, AT jobs run under the authority of whatever account the AT service runs (SYSTEM by default). Non administrators who can schedule AT commands, thus have a means to elevate their privileges. Although this setting is disabled, Server Operators will still be able to schedule jobs using Task Scheduler.HKSystem Administrator
SV-29526r1_rule 3.059 CCI-001764 HIGH The system is configured to autoplay removable media. Autoplay begins reading from a drive as soon as you insert media in the drive. As a result, the setup file of programs and the music on audio media starts immediately. By default, Autoplay is disabled on removable drives, such as the floppy disk drive (but not the CD-ROM drive), and on network drives. If you enable this policy, you can also disable Autoplay on all drives.HKHKSystem Administrator
SV-28494r2_rule AD.4029_2008 CCI-000366 MEDIUM Kerberos user logon restrictions must be enforced. This policy setting determines whether the Kerberos Key Distribution Center (KDC) validates every request for a session ticket against the user rights policy of the target computer. The policy is enabled by default which is the most secure setting for validating access to target resources is not circumvented.System Administrator
SV-28497r2_rule AD.4030_2008 CCI-000366 MEDIUM The Kerberos service ticket maximum lifetime must be limited to 600 minutes or less. This setting determines the maximum amount of time (in minutes) that a granted session ticket can be used to access a particular service. Session tickets are used only to authenticate new connections with servers. Ongoing operations are not interrupted if the session ticket used to authenticate the connection expires during the connection.System Administrator
SV-28499r2_rule AD.4031_2008 CCI-000366 MEDIUM The Kerberos user ticket lifetime must be limited to 10 hours or less. In Kerberos, there are 2 types of tickets: Ticket Granting Tickets (TGTs) and Service Tickets. Kerberos tickets have a limited lifetime so the time an attacker has to implement an attack is limited. This policy controls how long TGTs can be renewed. With Kerberos, the user’s initial authentication to the domain controller results in a TGT which is then used to request Service Tickets to resources. Upon startup, each computer gets a TGT before requesting a service ticket to the domain controller and any other computers it needs to access. For services that startup under a specified user account, users must always get a TGT first, then get Service Tickets to all computers and services accessed. System Administrator
SV-28501r2_rule AD.4032_2008 CCI-000366 MEDIUM The Kerberos user ticket renewal maximum lifetime must be limited to 7 days or less. This setting determines the period of time (in days) during which a user's Ticket Granting Ticket (TGT) may be renewed. This security configuration limits the amount of time an attacker has to crack the TGT and gain access.System Administrator
SV-28505r2_rule AD.4033_2008 CCI-001941 MEDIUM The computer clock synchronization tolerance must be limited to 5 minutes or less. This setting determines the maximum time difference (in minutes) that Kerberos will tolerate between the time on a client's clock and the time on a server's clock while still considering the two clocks synchronous. In order to prevent replay attacks, Kerberos uses timestamps as part of its protocol definition. For timestamps to work properly, the clocks of the client and the server need to be in sync as much as possible.System Administrator
SV-16933r1_rule 3.063 CCI-001090 HIGH Unauthorized named pipes are accessible with anonymous credentials. This is a Category 1 finding because the potential for gaining unauthorized system access. Pipes are internal system communications processes. They are identified internally by ID numbers that vary between systems. To make access to these processes easier, these pipes are given names that do not vary between systems. This setting controls which of these pipes anonymous users may access.System Administrator
SV-28589r1_rule 3.064 CCI-001090 HIGH Unauthorized registry paths are remotely accessible. This is a Category 1 finding because it could give unauthorized individuals access to the Registry. It controls which registry paths are accessible from a remote computer.System Administrator
SV-29704r1_rule 3.065 CCI-001090 HIGH Unauthorized shares can be accessed anonymously. This is a Category 1 finding because the potential for gaining unauthorized system access. Any shares listed can be accessed by any network user. This could lead to the exposure or corruption of sensitive data. Enabling this setting is very dangerous.HKSystem Administrator
SV-29230r1_rule 3.068 CCI-001090 HIGH Solicited Remote Assistance is allowed. This setting controls whether or not solicited remote assistance is allowed from this computer. Solicited assistance is help that is specifically requested by the user. This is a Category 1 finding because it may allow unauthorized parties access to the resources on the computer.HKSystem Administrator
SV-29234r1_rule 4.036 CCI-000366 HIGH The use of local accounts with blank passwords is not restricted to console logons only. This is a Category 1 finding because no accounts with blank passwords should exist on a system. The password policy should prevent this from occurring. However, if a local account with a blank password does exist, enabling this setting will limit the account to local console logon only.HKSystem Administrator
SV-29239r1_rule 5.017 CCI-000381 MEDIUM The user is allowed to launch Windows Messenger (MSN Messenger, .NET Messenger). This setting prevents the Windows Messenger client from being run. Instant Messaging clients must be in compliance of with the Instant Messaging STIG. Windows Messenger should not be active on Windows unless the instant messaging system is a Managed Enterprise Service for unclassified data for which the DAA has approved.trueSystem AdministratorInformation Assurance Officer
SV-29244r1_rule 5.018 CCI-000381 MEDIUM Windows Messenger (MSN Messenger, .NET messenger) is run at system startup. This setting prevents the automatic launch of Windows Messenger at user logon. Instant Messaging clients must be in compliance of with the Instant Messaging STIG. Windows Messenger should not be active on Windows unless the instant messaging system is a Managed Enterprise Service for unclassified data for which the DAA has approved.trueSystem AdministratorInformation Assurance Officer
SV-29708r1_rule 3.069 CCI-000366 MEDIUM The system can be removed from the docking station without logging on first. This setting controls the ability to undock the system without having to log on. Since the removal of a computer should be controlled, users should have to log on before undocking the computer to ensure that they have the appropriate rights to undock the system. In addition to software security settings, physical security should be in place to prevent unauthorized removal of computers.HKSystem Administrator
SV-29247r1_rule 4.043 CCI-000366 LOW The maximum age for machine account passwords is not set to requirements. This setting controls the maximum password age that a machine account may have. This setting should be set to no more than 30 days, ensuring the machine changes its password monthly.HKSystem Administrator
SV-29251r1_rule 4.044 CCI-002418 MEDIUM The system is not configured to require a strong session key. This setting controls the required strength of a session key. Setting this value in a domain containing Windows NT or older operating systems will prevent those systems from authenticating. This setting can also prevent a system from being joined to a domain.HKSystem AdministratorInformation Assurance Officer
SV-29259r1_rule 3.070 CCI-002038 MEDIUM The system is configured to permit storage of credentials or .NET Passports. This setting controls the storage of authentication credentials or .NET passports on the local system. Such credentials should never be stored on the local machine as that may lead to account compromise.HKSystem Administrator
SV-29264r1_rule 3.071 CCI-000366 MEDIUM The system is configured to give anonymous users Everyone rights. This setting helps define the permissions that anonymous users have. If this setting is enabled then anonymous users have the same rights and permissions as the built-in Everyone group. Anonymous users should not have these permissions or rights.HKSystem AdministratorInformation Assurance Officer
SV-29267r1_rule 3.072 CCI-001090 MEDIUM The system is not configured to use the Classic security model. Windows includes two network-sharing security models - Classic and Guest only. With the classic model, local accounts must be password protected; otherwise, anyone can use guest user accounts to access shared system resources.HKSystem Administrator
SV-29270r1_rule 3.073 CCI-000196 HIGH The system is configured to store the LAN Manager hash of the password in the SAM. This setting controls whether or not a LAN Manager hash of the password is stored in the SAM the next time the password is changed. The LAN Manager hash is a weak encryption algorithm and there are several tools available that use this hash to retrieve account passwords.HKSystem AdministratorInformation Assurance Officer
SV-29273r1_rule 3.075 CCI-000366 MEDIUM The system is not configured to recommended LDAP client signing requirements. This setting controls the signing requirements for LDAP clients. This setting should be set to Negotiate signing or Require signing depending on the environment and type of LDAP server in use.HKSystem Administrator
SV-29530r1_rule 3.076 CCI-000366 MEDIUM The system is not configured to meet the minimum requirement for session security for NTLM SSP based Clients. Microsoft has implemented a variety of security support providers for use with RPC sessions. In a homogenous Windows environment, all of the options should be enabled and testing should be performed in a heterogeneous environment to determine the maximum-security level that provides reliable functionality.trueMicrosoft warns that setting these may prevent the client from communicating with legacy servers that do not support them. “Require NTLMv2 session security” will prevent authentication, if the “Network security: LAN Manager authentication level” is set to permit NTLM or LM authentication. System AdministratorInformation Assurance Officer
SV-29533r1_rule 3.077 CCI-002450 MEDIUM The system is not configured to use FIPS compliant Algorithms for Encryption, Hashing, and Signing. This setting ensures that the system uses algorithms that are FIPS compliant for encryption, hashing, and signing. FIPS compliant algorithms meet specific standards established by the U.S. Government and should be the algorithms used for all OS encryption functions.Clients with this setting enabled will not be able to communicate via digitally encrypted or signed protocols with servers that do not support these algorithms. Both the Browser and Web Server must be configured to use TLS, or the browser will not be able to connect to a secure site.HKSystem Administrator
SV-29536r2_rule 3.078 CCI-000366 MEDIUM The system must be configured to require case insensitivity for non-Windows subsystems. This setting controls the behavior of non-Windows subsystems when dealing with the case of arguments or commands. Case sensitivity could lead to the access of files or commands that must be restricted. To prevent this from happening, case insensitivity restrictions must be required.HKSystem Administrator
SV-16938r1_rule 5.038 CCI-000054 MEDIUM Terminal Services is not configured to limit users to one remote session (Terminal Server Role) This setting limits users to one remote session. It is possible, if this setting is disabled, for users to establish multiple sessions.System AdministratorInformation Assurance Officer
SV-16953r2_rule 5.043 CCI-000068 MEDIUM Terminal Services is not configured with the client connection encryption set to the required level. Remote connections must be encrypted to prevent interception of data or sensitive information. Selecting “High Level” will ensure encryption of Terminal Services sessions in both directions.HKSystem Administrator
SV-29101r1_rule 5.044 CCI-000366 MEDIUM Terminal Services is configured to use a common temporary folder for all sessions (Terminal Server Role). This setting, which is located under the Temporary Folders section of the Terminal Services configuration option, controls the use of per session temporary folders or of a communal temporary folder. If this setting is enabled, only one temporary folder is used for all terminal services sessions. If a communal temporary folder is used, it might be possible for users to access other users temporary folders.HKSystem Administrator
SV-29103r1_rule 5.045 CCI-000366 MEDIUM Terminal Services is not configured to delete temporary folders (Terminal Server Role). This setting, which is located under the Temporary Folders section of the Terminal Services configuration option, controls the deletion of the temporary folders when the session is terminated. Temporary folders should always be deleted after a session is over to prevent hard disk clutter and potential leakage of information.HKSystem Administrator
SV-29606r2_rule 3.080 CCI-000366 MEDIUM The system is configured to prevent background refresh of Group Policy. If this setting is enabled, then Group Policy settings are not refreshed while a user is currently logged on. This could lead to instances when a user does not have the latest changes to a policy applied and is therefore operating in an insecure context.HKSystem Administrator
SV-29283r1_rule 3.082 CCI-001090 MEDIUM The system is configured to allow unsolicited remote assistance offers. This setting controls whether unsolicited offers of help to this computer are allowed. The list of users allowed to offer remote assistance to this system is accessed by pressing the Helpers button.HKSystem Administrator
SV-29718r1_rule 3.088 CCI-000366 MEDIUM The system is not configured to use Safe DLL Search Mode. The default search behavior, when an application calls a function in a Dynamic Link Library (DLL), is to search the current directory followed by the directories contained in the systems path environment variable. An unauthorized DLL inserted into an applications working directory could allow malicious code to be run on the system. Creating the following registry key and setting the appropriate value forces the system to search the %Systemroot% for the DLL before searching the current directory or the rest of the path.HKSystem Administrator
SV-40097r2_rule 5.060 CCI-001812 MEDIUM Media Player must be configured to prevent automatic checking for updates. Uncontrolled system updates can introduce issues to a system. The automatic check for updates performed by Windows Media Player must be disabled to ensure a constant platform and to prevent the introduction of unknown\untested software on the system.HKSystem Administrator
SV-29357r1_rule 3.089 CCI-000366 MEDIUM The system is not configured to meet the minimum requirement for session security for NTLM SSP based Servers.

SV-29370r2_rule 3.101 CCI-002385 LOW The system must be configured to ignore NetBIOS name release requests except from WINS servers. Configuring the system to ignore name release requests, except from WINS servers, prevents a denial of service (DoS) attack. The DoS consists of sending a NetBIOS name release request to the server for each entry in the server's cache, causing a response delay in the normal operation of the servers WINS resolution capability.HKSystem Administrator
SV-41837r2_rule AD.3106_2008 CCI-002418 MEDIUM Domain Controllers must require LDAP signing. Unsigned network traffic is susceptible to man-in-the-middle attacks where an intruder captures packets between the server and the client and modifies them before forwarding them to the client. In the case of an LDAP server, this means that an attacker can cause a client to make decisions based on false records from the LDAP directory. You can lower the risk of an attacker pulling this off in a corporate network by implementing strong physical security measures to protect the network infrastructure. Furthermore, implementing Internet Protocol security (IPSec) authentication header mode (AH), which performs mutual authentication and packet integrity for Internet Protocol (IP) traffic, can make all types of man-in-the-middle attacks extremely difficult.trueHKSystem AdministratorECSC-1
SV-41844r1_rule AD.3107_2008 CCI-000366 LOW The domain controller must be configured to allow reset of machine account passwords. Enabling this setting on all domain controllers in a domain prevents domain members from changing their computer account passwords.

SV-29732r1_rule 3.108 CCI-001090 HIGH Unauthorized registry paths and sub-paths are remotely accessible. The registry is a database for computer configuration information, much of which is sensitive. An attacker could use this to facilitate unauthorized activities. To reduce the risk of this happening, it is also lowered by the fact that the default ACLs assigned throughout the registry are fairly restrictive and they help to protect it from access by unauthorized users. System Administrator
SV-29733r3_rule 3.109 CCI-000186 MEDIUM Users must be required to enter a password to access private keys stored on the computer. Configuring this setting so that users must provide a password (distinct from their domain password) every time they use a key makes it more difficult for an attacker to access locally stored user keys, even if the attacker takes control of the user's computer and determines their logon password.

SV-29734r1_rule 3.110 CCI-000381 LOW Optional Subsystems are permitted to operate on the system. The POSIX subsystem is an Institute of Electrical and Electronic Engineers (IEEE) standard that defines a set of operating system services. The POSIX Subsystem is required if the server supports applications that use that subsystem. The subsystem introduces a security risk relating to processes that can potentially persist across logins. That is, if a user starts a process and then logs out, there is a potential that the next user who logs in to the system could access the previous users process. This is dangerous because the process started by the first user may retain that users system privileges; anything the second user does with that process will be performed with the privileges of the first user. trueHKSystem Administrator

SV-16952r1_rule 5.103 CCI-001453 MEDIUM The Terminal Server does not require secure RPC communication (Terminal Server Role). Allowing unsecure RPC communication exposes the server to man in the middle attacks and data disclosure attacks. A man in the middle attack occurs when an intruder captures packets between a client and server and modifies them before allowing the packets to be exchanged. Usually the attacker will modify the information in the packets in an attempt to cause either the client or server to reveal sensitive information. HKSystem Administrator

SV-88183r1_rule WIN00-000170 CCI-000381 MEDIUM The Server Message Block (SMB) v1 protocol must be disabled on the SMB server. SMBv1 is a legacy protocol that uses the MD5 algorithm as part of SMB. MD5 is known to be vulnerable to a number of attacks such as collision and preimage attacks as well as not being FIPS compliant. Disabling SMBv1 support may prevent access to file or print sharing resources with systems or devices that only support SMBv1. File shares and print services hosted on Windows Server 2003 are an example, however Windows Server 2003 is no longer a supported operating system. Some older network attached devices may only support SMBv1.
