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

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

The Windows Time Service controls time synchronization settings. Time synchronization is essential for authentication and auditing purposes. If the Windows Time Service is used, it must synchronize with a secure, authorized time source. Domain joined systems are automatically configured to synchronize with domain controllers. If an NTP server is configured, it must synchronize with a secure, authorized time source.System Administrator
Checks: C-80213r2_chk

Open "Windows PowerShell" or an elevated "Command Prompt" (run as administrator). Enter "W32tm /query /configuration". Domain-joined systems are automatically configured with a "Type" of "NT5DS" to synchronize with domain controllers and would not be a finding. If systems are configured with a "Type" of "NTP", including standalone systems and the forest root domain controller with the PDC Emulator role, and do not have a DoD time server defined for "NTPServer", this is a finding. (See V-8557 in the Active Directory Forest STIG for the time source requirement of the forest root domain PDC emulator.) If an alternate time synchronization tool is used and is not enabled or not configured to synchronize with a DoD time source, this is a finding. The US Naval Observatory operates stratum 1 time servers, identified at http://tycho.usno.navy.mil/ntp.html. Time synchronization will occur through a hierarchy of time servers down to the local level. Clients and lower-level servers will synchronize with an authorized time server in the hierarchy.

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

Setting application accounts to expire may cause applications to stop functioning.

Application/service account passwords must be at least 15 characters and follow complexity requirements for all passwords.System AdministratorInformation Assurance Officer
Checks: C-78971r4_chk

Determine if manually managed application/service accounts exist. If none exist, this is NA. Verify the organization has a policy to ensure passwords for manually managed application/service accounts are at least 15 characters in length. It must also require the passwords be changed at least annually or when an administrator with knowledge of the password leaves the organization. If such a policy does not exist or has not been implemented, this is a finding. Identify manually managed application/service accounts. To determine the date a password was last changed: Domain controllers: Open "Windows PowerShell" with elevated privileges (run as administrator). Enter "Import-Module ActiveDirectory". (This only needs to be run once during a PowerShell session.) Enter "Get-ADUser -Identity [application account name] -Properties PasswordLastSet | FL Name, PasswordLastSet", where [application account name] is the name of the manually managed application/service account. If the "PasswordLastSet" date is more than one year old, this is a finding. Member servers and standalone systems: Open "Windows PowerShell" or "Command Prompt". Enter 'Net User [application account name] | Find /i "Password Last Set"', where [application account name] is the name of the manually managed application/service account. If the "Password Last Set" date is more than one year old, this is a finding. Note: Other queries or tools may be used. The organization must be able to demonstrate the results are valid and meet the intent of the requirement.

Registry Hive: HKEY_LOCAL_MACHINE Registry Path: \SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System\Kerberos\Parameters\ Value Name: SupportedEncryptionTypes Type: REG_DWORD The values are determined by the selection of encryption suites in the policy "Network Security: Configure encryption types allowed for Kerberos". Due to the various possible combinations, it is not possible to include all acceptable values as viewed directly in the registry. The value must be converted to binary to determine configuration of specific bits. This will determine whether this is a finding. Note the value for the registry key. For example when all suites, including the DES suites are selected, the value will be "0x7fffffff (2147483647)". Open the Windows calculator (Run/Search for "calc"). Select "View", then "Programmer". Select "Dword" and either "Hex" or "Dec". Enter the appropriate form of the value found for the registry key (e.g., Hex - enter 0x7fffffff, Dec - enter 2147483647). Select "Bin". The returned value may vary in length, up to 32 characters. If either of the 2 right most characters are "1", this is a finding. If both of the 2 right most characters are "0", this is not a finding.

Maintaining an audit trail of system activity logs can help identify configuration errors, troubleshoot service disruptions, and analyze compromises that have occurred as well as detecting attacks. Audit logs are necessary to provide a trail of evidence in case the system or network is compromised. Collecting this data is essential for analyzing the security of information assets and detecting signs of suspicious and unexpected behavior. System Integrity records events related to violations of integrity to the security subsystem. System Administrator
Checks: C-34127r1_chk

Security Option “Audit: Force audit policy subcategory settings (Windows Vista or later) to override audit policy category settings” must be set to “Enabled” (V-14230) for the detailed auditing subcategories to be effective. Use the AuditPol tool to review the current Audit Policy configuration: -Open a Command Prompt with elevated privileges (“Run as Administrator”). -Enter “AuditPol /get /category:*”. Compare the Auditpol settings with the following. If the system does not audit the following, this is a finding: System -&gt; System Integrity - Failure

Fix: F-29809r1_fix

Detailed auditing subcategories are configured in Security Settings -> Advanced Audit Policy Configuration. The summary level settings under Security Settings -> Local Policies -> Audit Policy will not be enforced (see V-14230). Configure the policy value for Computer Configuration -> Windows Settings -> Security Settings -> Advanced Audit Policy Configuration -> System Audit Policies -> System -> "Audit System Integrity" with “Failure” selected.

Using applications that access the internet or have potential internet sources using administrative privileges exposes a system to compromise. If a flaw in an application is exploited while running as a privileged user, the entire system could be compromised. Web browsers and email are common attack vectors for introducing malicious code and must not be run with an administrative user account. Since administrative user accounts may generally change or work around technical restrictions for running a web browser or other applications, it is essential that policy requires administrative users not access the internet or use applications, such as email. The policy should define specific exceptions for local service administration. These exceptions may include HTTP(S)-based tools that are used for the administration of the local system, services, or attached devices. Technical means such as application whitelisting can be used to enforce the policy to ensure compliance.
Checks: C-74331r2_chk

Determine whether administrative accounts are prevented from using applications that access the Internet, such as web browsers, or with potential Internet sources, such as email, except as necessary for local service administration. The organization must have a policy that prohibits administrative accounts from using applications that access the Internet, such as web browsers, or with potential Internet sources, such as email, except as necessary for local service administration. The policy should define specific exceptions for local service administration. These exceptions may include HTTP(S)-based tools that are used for the administration of the local system, services, or attached devices. Technical measures such as the removal of applications or application whitelisting must be used where feasible to prevent the use of applications that access the Internet. If accounts with administrative privileges are not prevented from using applications that access the Internet or with potential Internet sources, this is a finding.

Utilizing a whitelist provides a configuration management method for allowing the execution of only authorized software. Using only authorized software decreases risk by limiting the number of potential vulnerabilities. The organization must identify authorized software programs and only permit execution of authorized software. The process used to identify software programs that are authorized to execute on organizational information systems is commonly referred to as whitelisting.
Checks: C-69267r4_chk

This is applicable to unclassified systems; for other systems this is NA. Verify the operating system employs a deny-all, permit-by-exception policy to allow the execution of authorized software programs. If an application whitelisting program is not in use on the system, this is a finding. Configuration of whitelisting applications will vary by the program. AppLocker is a whitelisting application built into Windows Server 2008 R2. A deny-by-default implementation is initiated by enabling any AppLocker rules within a category, only allowing what is specified by defined rules. If AppLocker is used, perform the following to view the configuration of AppLocker: Open PowerShell.
