The Windows Server 2008 R2 Security Technical Implementation Guide (STIG) is published as a tool to improve the security of Department of Defense (DoD) information systems. The requirements were developed from DoD consensus, as well as the Windows Server 2008 R2 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-32242r3_rule 2.005 CCI-000366 HIGH Systems must be at supported service pack (SP) or release 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-32280r1_rule 3.007 CCI-000366 LOW The shutdown option will not be available 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-32248r1_rule 2.008 CCI-000213 HIGH Local volumes will be 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. trueSystem AdministratorInformation Assurance Officer
SV-32281r4_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-32282r3_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-32283r1_rule 3.018 CCI-001090 HIGH Anonymous enumeration of shares will be 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. By default, Windows allows anonymous users to list account names and enumerate share names.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-32284r2_rule 4.002 CCI-000044 MEDIUM The system must lockout accounts after 3 invalid logon attempts within a specified time period. 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-32285r2_rule 4.003 CCI-000044 MEDIUM The period of time before the invalid logon counter is reset must be configured to at least 60 minutes. 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-32286r2_rule 4.004 CCI-002238 MEDIUM The account lockout duration must be configured to require an administrator to unlock an account. 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. A value of 0 will require an administrator to unlock the account.HKSystem Administrator
SV-32287r2_rule WINUR-000003 CCI-002235 HIGH Unauthorized accounts must not have the Act as part of the operating system user right. Inappropriate granting of user rights can provide system, administrative, and other high-level capabilities. Accounts with the "Act as part of the operating system" user right can assume the identity of any user and gain access to resources that user is authorized to access. Any accounts with this right can take complete control of a system.If an application requires this user right, this can be downgraded to a CAT III if the following conditions are met: Vendor documentation must support the requirement for having the user right. The requirement must be documented with the ISSO. Passwords for accounts with this user right must be protected as highly privileged accounts. The application account must meet requirements for application account passwords, such as length and required changes frequency (V-14271).System AdministratorInformation Assurance Officer
SV-32288r2_rule 4.011 CCI-000199 MEDIUM The maximum password age must be configured to 60 days or less. The longer passwords are in use, the greater the opportunity for someone to gain unauthorized knowledge of them. Scheduled changing of passwords hinders the ability of unauthorized system users to crack passwords and gain access to a system.HKSystem Administrator
SV-32289r2_rule 4.012 CCI-000198 MEDIUM The minimum password age must be configured to at least 1 day. 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-32290r3_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 users can recycle the same password several times without being required to change it 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-32291r2_rule 4.020 CCI-000804 MEDIUM The built-in guest account must be 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.System Administrator
SV-32292r1_rule 4.021 CCI-000366 MEDIUM The built-in guest account will be 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-32293r1_rule 4.022 CCI-000366 MEDIUM The built-in administrator account will be 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-32295r1_rule 4.006 CCI-001133 LOW Users will be forcibly disconnected when their logon hours expire. Users should 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. This protects critical and sensitive network data from exposure to unauthorized personnel with physical access to the computer.HKSystem Administrator
SV-32296r2_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-32297r2_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-32298r2_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-32299r1_rule 3.029 CCI-001812 LOW The print driver installation privilege will be restricted to administrators. Allowing users to install drivers can introduce malware or cause the instability of a system. This capability should be restricted to the Administrators and Print Operators groups.System AdministratorInformation Assurance Officer
SV-32300r1_rule 3.031 CCI-000366 HIGH The LanMan authentication level will be set to Send NTLMv2 response only\refuse LM & NTLM. The Kerberos v5 authentication protocol is the default for authentication of users who are logging on to domain accounts. The Windows NTLM protocol is retained in later Windows versions for compatibility with clients and servers that are running earlier versions. 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-32301r1_rule 3.032 CCI-000366 MEDIUM The Ctrl+Alt+Del security attention sequence for logons will be enabled. 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-32302r5_rule WINUR-000017-MS CCI-000213 MEDIUM The Deny access to this computer from the network user right on member servers must be configured to prevent access from highly privileged domain accounts and all local accounts on domain systems and unauthenticated access on all systems. Inappropriate granting of user rights can provide system, administrative, and other high level capabilities. The "Deny access to this computer from the network" right defines the accounts that are prevented from logging on from the network. In an Active Directory Domain, denying logons to the Enterprise Admins and Domain Admins groups on lower trust systems helps mitigate the risk of privilege escalation from credential theft attacks which could lead to the compromise of an entire domain. Local accounts on domain-joined systems must also be assigned this right to decrease the risk of lateral movement resulting from credential theft attacks. The Guests group must be assigned this right to prevent unauthenticated access.System Administrator
SV-32303r1_rule 3.047 CCI-000366 MEDIUM The Smart Card removal option will be configured to Force Logoff or Lock Workstation. 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 AdministratorInformation Assurance Officer
SV-32304r2_rule 3.048 CCI-000366 LOW The Recovery Console SET command must be disabled. The Recovery Console SET command allows environment variables to be set in the Recovery Console. This permits access to all drives and folders and the copying of files to removable media which could expose sensitive information.HKSystem Administrator
SV-32305r1_rule 3.049 CCI-000366 HIGH The Recovery Console option will be set to prevent automatic logon to the system. This is a Category 1 finding because if this option is set, the Recovery Console does not require you to provide a password and will automatically log on to the system, giving Administrator access to system files. By default, the Recovery Console requires you to provide the password for the Administrator account before accessing the system.HKSystem Administrator
SV-32513r1_rule 3.046 CCI-002418 MEDIUM The Windows SMB server will 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-32306r1_rule 3.043 CCI-002418 MEDIUM Outgoing secure channel traffic will be 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-32307r1_rule 3.042 CCI-002418 MEDIUM Outgoing secure channel traffic will be 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-32308r1_rule 3.044 CCI-000366 LOW The computer account password will not be prevented from being reset. Computer account passwords are changed automatically on a regular basis. 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 30 days. HKSystem Administrator
SV-32309r1_rule 3.045 CCI-002418 MEDIUM The Windows SMB client will be 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. This policy is defined by default in Local Computer Policy, where it is enabled by default.HKSystem Administrator
SV-32310r1_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-32311r1_rule 3.054 CCI-000366 LOW Users will be 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-32312r1_rule 3.055 CCI-000366 LOW The default permissions of Global system objects will be 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-32313r2_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-32314r1_rule 3.057 CCI-000196 MEDIUM Reversible password encryption will be 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-32315r1_rule 3.059 CCI-001764 HIGH Autoplay will be disabled for all drives. 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-32481r2_rule 3.063-MS CCI-001090 HIGH Named pipes that can be accessed anonymously will be configured to contain no values. This is a Category 1 finding due to 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 may be accessed anonymously.System Administrator
SV-32484r2_rule 3.064 CCI-001090 HIGH Unauthorized remotely accessible registry paths must not be configured. The registry is integral to the function, security, and stability of the Windows system. Some processes may require remote access to the registry. This setting controls which registry paths are accessible from a remote computer. These registry paths must be limited, as they could give unauthorized individuals access to the registry.System Administrator
SV-32317r1_rule 3.065 CCI-001090 HIGH Network shares that can be accessed anonymously will not be allowed. 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-32318r1_rule 3.068 CCI-001090 HIGH Solicited Remote Assistance will not be 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-32319r1_rule 4.036 CCI-000366 HIGH The use of local accounts with blank passwords will be 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-32320r1_rule 3.069 CCI-000366 MEDIUM A system must be logged on to before removing from a docking station. 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-32321r1_rule 4.043 CCI-000366 LOW The maximum age for machine account passwords will be 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-32322r1_rule 4.044 CCI-002418 MEDIUM The system will be 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-32336r1_rule 3.070 CCI-002038 MEDIUM The system will be configured to prevent the storage of passwords and credentials This setting controls the storage of passwords and credentials for network authentication on the local system. Such credentials should never be stored on the local machine as that may lead to account compromise. HKSystem Administrator
SV-32337r1_rule 3.071 CCI-000366 MEDIUM The system will be configured to prevent anonymous users from having the same rights as the Everyone group. 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 Administrator
SV-32338r1_rule 3.072 CCI-001090 MEDIUM The system will be 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-32339r1_rule 3.073 CCI-000196 HIGH The system will be configured to prevent the storage of the LAN Manager hash of passwords. 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 Administrator
SV-32468r1_rule 3.074 CCI-001133 MEDIUM The system will be configured to force users to log off when their allowed logon hours expire. This setting controls whether or not users are forced to log off when their allowed logon hours expire. If logon hours are set for users, then this should be enforced.HKSystem Administrator
SV-32340r1_rule 3.075 CCI-000366 MEDIUM The system will be configured to the required LDAP client signing level. 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-32341r1_rule 3.076 CCI-000366 MEDIUM The system will be configured to meet the minimum session security requirement for NTLM SSP based clients. Windows 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-32342r1_rule 3.077 CCI-002450 MEDIUM The system will be 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-32343r2_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-32498r1_rule 5.038 CCI-000054 MEDIUM Remote Desktop Services will limit users to one remote session. This setting limits users to one remote session. It is possible, if this setting is disabled, for users to establish multiple sessions.trueSystem AdministratorInformation Assurance Officer
SV-32490r1_rule 5.042 CCI-002038 MEDIUM Remote Desktop Services will always prompt a client for passwords upon connection. This setting controls the ability of users to supply passwords automatically as part of their Remote Desktop session. Disabling this setting would allow anyone to use the stored credentials in a connection item to connect to the host.HKSystem Administrator
SV-32491r2_rule 5.043 CCI-000068 MEDIUM Remote Desktop Services will be 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 Remote Desktop Services sessions in both directions.HKSystem Administrator
SV-32492r1_rule 5.044 CCI-000366 MEDIUM Remote Desktop Services will be configured to use session-specific temporary folders. This setting 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 remote desktop sessions. If a communal temporary folder is used, it might be possible for users to access other users’ temporary folders. HKSystem Administrator
SV-32493r1_rule 5.045 CCI-000366 MEDIUM Remote Desktop Services will delete temporary folders when a session is terminated. This setting 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-32494r1_rule 5.046 CCI-001133 MEDIUM Remote Desktop Services will be configured to set a time limit for disconnected sessions. This setting controls how long a session will remain open if it is unexpectedly terminated. Such sessions should be terminated as soon as possible. HKSystem Administrator
SV-32495r1_rule 5.047 CCI-001133 MEDIUM Remote Desktop Services will be configured to disconnect an idle session after the specified time period. This setting controls how long a session may be idle before it is automatically disconnected from the server. Users should disconnect if they plan on being away from their terminals for extended periods of time. Idle sessions should be disconnected after 15 minutes. HKSystem Administrator
SV-32344r2_rule 3.080 CCI-000366 MEDIUM The system will be configured to enable the 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-32345r1_rule 3.082 CCI-001090 MEDIUM The system will be configured to prevent 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-32348r1_rule 3.088 CCI-000366 MEDIUM The system will be 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-40099r2_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-32352r1_rule 3.089 CCI-000366 MEDIUM The system will be configured to meet the minimum session security requirement for NTLM SSP based servers. Windows 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 server from communicating with legacy clients 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-32353r2_rule 3.092 CCI-000139 LOW The system must generate an audit event when the audit log reaches a percentage of full threshold. Audit records may be lost if the security log becomes full. When the audit log reaches a given percent full, an audit event is written to the security log. An event is recorded as a success audit under the category of System. This option may be especially useful if the audit logs are set to be cleared manually.System AdministratorInformation Assurance OfficerECRR-1
SV-32354r1_rule 3.094 CCI-000366 LOW The system will be configured to prevent IP source routing. Protects against IP source routing spoofing.HKSystem Administrator
SV-32355r1_rule 3.095 CCI-000366 LOW The system will be configured to prevent ICMP redirects from overriding OSPF generated routes. When disabled, forces ICMP to be routed via shortest path first.HKSystem Administrator
SV-32356r1_rule 3.104 CCI-002385 LOW The system will be configured to disable the Internet Router Discover Protocol (IRDP). Enables or disables the Internet Router Discovery Protocol (IRDP) used to detect and configure Default Gateway addresses on the computer.HKSystem Administrator
SV-32357r1_rule 3.097 CCI-002385 LOW The system will be configured to limit how often keep-alive packets are sent. Controls how often TCP sends a keep-alive packet in attempting to verify that an idle connection is still intact.HKSystem Administrator
SV-32358r2_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-32359r2_rule 5.098 CCI-002385 LOW The system must limit how many times unacknowledged TCP data is retransmitted. In a SYN flood attack, the attacker sends a continuous stream of SYN packets to a server, and the server leaves the half-open connections open until it is overwhelmed and no longer able to respond to legitimate requests. HKSystem Administrator

SV-32362r1_rule 3.110 CCI-000381 LOW Optional Subsystems will not be 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
