The longer a password is in use, the greater the opportunity for someone to gain unauthorized knowledge of the password. The password for the built-in Administrator account must be changed at least annually or when any member of the administrative team leaves the organization. It is highly recommended to use Microsoft's Local Administrator Password Solution (LAPS). Domain-joined systems can configure this to occur more frequently. LAPS will change the password every "30" days by default. The AO still has the overall authority to use another equivalent capability to accomplish the check.
Checks: C-26942r471071_chk

Review the password last set date for the built-in Administrator account. Domain controllers: Open "Windows PowerShell". Enter "Get-ADUser -Filter * -Properties SID, PasswordLastSet | Where SID -Like "*-500" | FL Name, SID, PasswordLastSet". If the "PasswordLastSet" date is greater than one year old, this is a finding. Member servers and standalone systems: Open "Windows PowerShell" or "Command Prompt". Enter 'Net User [account name] | Find /i "Password Last Set"', where [account name] is the name of the built-in administrator account. (The name of the built-in Administrator account must be changed to something other than "Administrator" per STIG requirements.) If the "PasswordLastSet" date is greater than one year old, this is a finding.

Fix: F-26930r793245_fix

Change the built-in Administrator account password at least annually or whenever an administrator leaves the organization. More frequent changes are recommended. It is highly recommended to use Microsoft's LAPS on domain-joined member servers to accomplish this. The AO still has the overall authority to use another equivalent capability to accomplish the check.

c
Administrative accounts must not be used with applications that access the Internet, such as web browsers, or with potential Internet sources, such as email.

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 account. Since administrative accounts may generally change or work around technical restrictions for running a web browser or other applications, it is essential that policy requires administrative accounts to 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-26943r471074_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.

Fix: F-26931r471075_fix

Establish and enforce 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. 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. Implement technical measures where feasible such as removal of applications or use of application whitelisting to restrict the use of applications that can access the Internet.

Setting application accounts to expire may cause applications to stop functioning. However, not changing them on a regular basis exposes them to attack. If managed service accounts are used, this alleviates the need to manually change application account passwords.
Checks: C-26947r471086_chk

Determine if manually managed application/service accounts exist. If none exist, this is NA. If passwords for manually managed application/service accounts are not changed at least annually or when an administrator with knowledge of the password leaves the organization, this is a finding. Identify manually managed application/service accounts. To determine the date a password was last changed: Domain controllers: Open "Windows PowerShell". 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.

Utilizing an allowlist 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 allowlisting.
Checks: C-26954r890487_chk

Verify the operating system employs a deny-all, permit-by-exception policy to allow the execution of authorized software programs. If an application allowlisting program is not in use on the system, this is a finding. Configuration of allowlisting applications will vary by the program. AppLocker is an allowlisting application built into Windows Server 2012. 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. If the AppLocker PowerShell module has not been previously imported, execute the following first: Import-Module AppLocker Execute the following command, substituting [c:\temp\file.xml] with a location and file name appropriate for the system: Get-AppLockerPolicy -Effective -XML > c:\temp\file.xml This will produce an xml file with the effective settings that can be viewed in a browser or opened in a program such as Excel for review.

Information can be either unintentionally or maliciously disclosed or modified during preparation for transmission, for example, during aggregation, at protocol transformation points, and during packing/unpacking. These unauthorized disclosures or modifications compromise the confidentiality or integrity of the information. Ensuring the confidentiality of transmitted information requires the operating system to take measures in preparing information for transmission. This can be accomplished via access control and encryption. Use of this requirement will be limited to situations where the data owner has a strict requirement for ensuring data integrity and confidentiality is maintained at every step of the data transfer and handling process. When transmitting data, operating systems need to support transmission protection mechanisms such as TLS, encrypted VPNs, or IPSEC.
Checks: C-26955r471110_chk

If the data owner has a strict requirement for ensuring data integrity and confidentiality is maintained at every step of the data transfer and handling process, verify protection methods such as TLS, encrypted VPNs, or IPSEC have been implemented.

This requirement addresses protection of user-generated data, as well as operating system-specific configuration data. Organizations may choose to employ different mechanisms to achieve confidentiality and integrity protections, as appropriate, in accordance with the security category and/or classification of the information. Selection of a cryptographic mechanism is based on the need to protect the integrity of organizational information. The strength of the mechanism is commensurate with the security category and/or classification of the information. Organizations have the flexibility to either encrypt all information on storage devices (i.e., full disk encryption) or encrypt specific data structures (e.g., files, records, or fields).
Checks: C-26956r471113_chk

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 detect 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. Enabling PowerShell script block logging will record detailed information from the processing of PowerShell commands and scripts. This can provide additional detail when malware has run on a system.

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.
Checks: C-27060r857219_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.

Allowing unsecure RPC communication exposes the system 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.

Windows shares are a means by which files, folders, printers, and other resources can be published for network users to access. Improper configuration can permit access to devices and data beyond a user's need.
Checks: C-27123r471614_chk

Open "Devices and Printers" in Control Panel or through Search. If there are no printers configured, this is NA.(Exclude Microsoft Print to PDF and Microsoft XPS Document Writer, which do not support sharing.) For each configured printer: Right click on the printer. Select "Printer Properties". Select the "Sharing" tab. View whether "Share this printer" is checked. For any printers with "Share this printer" selected: Select the Security tab. If any standard user accounts or groups have permissions other than "Print", this is a finding. Standard users will typically be given "Print" permission through the Everyone group. "All APPLICATION PACKAGES" and "CREATOR OWNER" are not considered standard user accounts for this requirement.

Failure to verify a certificate's revocation status can result in the system accepting a revoked, and therefore unauthorized, certificate. This could result in the installation of unauthorized software or a connection for rogue networks, depending on the use for which the certificate is intended. Querying for certificate revocation mitigates the risk that the system will accept an unauthorized certificate.

The FTP service allows remote users to access shared files and directories. Allowing anonymous FTP connections makes user auditing difficult. Using accounts that have administrator privileges to log on to FTP risks that the userid and password will be captured on the network and give administrator access to an unauthorized user.
Checks: C-27136r471653_chk

If FTP is not installed on the system, this is NA. Determine the IP address and port number assigned to FTP sites from documentation or configuration. If Microsoft FTP is used, open "Internet Information Services (IIS) Manager". Select "Sites" under the server name. For any sites that reference FTP, view the Binding information for IP address and port. The standard port for FTP is 21, however this may be changed. Open a "Command Prompt". Attempt to log on as the user "anonymous" with the following commands: Note: Returned results may vary depending on the FTP server software. C:\> "ftp" ftp> "Open IP Address Port" (Substituting [IP Address] and [Port] with the information previously identified. If no IP Address was listed in the Binding, attempt using "localhost".)

If temporary user accounts remain active when no longer needed or for an excessive period, these accounts may be used to gain unauthorized access. To mitigate this risk, automated termination of all temporary accounts must be set upon account creation. Temporary accounts are established as part of normal account activation procedures when there is a need for short-term accounts without the demand for immediacy in account activation. If temporary accounts are used, the operating system must be configured to automatically terminate these types of accounts after a DoD-defined time period of 72 hours. To address access requirements, many operating systems may be integrated with enterprise-level authentication/access mechanisms that meet or exceed access control policy requirements.
Checks: C-27138r471659_chk

Determine if temporary user accounts are used and identify any that exist. If none exist, this is NA. Review temporary user accounts for expiration dates. Open "PowerShell". Domain Controllers: Enter "Search-ADAccount -AccountExpiring -TimeSpan 3:00:00:00 | FT Name, AccountExpirationDate" This will return any accounts configured to expire within the next 3 days. (The "TimeSpan" value to can be changed to find accounts configured to expire at various times such as 30 for the next month.) If any accounts identified as temporary are not listed, this is a finding. For any temporary accounts returned by the previous query: Enter "Get-ADUser -Identity [Name] -Property WhenCreated" to determine when the account was created. If the "WhenCreated" date and "AccountExpirationDate" from the previous query are greater than 3 days apart, this is a finding. Member servers and standalone systems: Enter "Net User [username]", where [username] is the name of the temporary user account. If "Account expires" has not been defined within 72 hours for any temporary user account, this is a finding. If the "Password last set" date and "Account expires" date are greater than 72 hours apart, this is a finding. (Net User does not provide an account creation date.)

Emergency administrator accounts are privileged accounts which are established in response to crisis situations where the need for rapid account activation is required. Therefore, emergency account activation may bypass normal account authorization processes. If these accounts are automatically disabled, system maintenance during emergencies may not be possible, thus adversely affecting system availability. Emergency administrator accounts are different from infrequently used accounts (i.e., local logon accounts used by system administrators when network or normal logon/access is not available). Infrequently used accounts are not subject to automatic termination dates. Emergency accounts are accounts created in response to crisis situations, usually for use by maintenance personnel. The automatic expiration or disabling time period may be extended as needed until the crisis is resolved; however, it must not be extended indefinitely. A permanent account should be established for privileged users who need long-term maintenance accounts. To address access requirements, many operating systems can be integrated with enterprise-level authentication/access mechanisms that meet or exceed access control policy requirements.
Checks: C-27139r471662_chk

Determine if emergency administrator accounts are used and identify any that exist. If none exist, this is NA.

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, and anything the second user does with that process will be performed with the privileges of the first user.

If the private key is discovered, an attacker can use the key to authenticate as an authorized user and gain access to the network infrastructure. The cornerstone of the PKI is the private key used to encrypt or digitally sign information. If the private key is stolen, this will lead to the compromise of the authentication and non-repudiation gained through PKI because the attacker can use the private key to digitally sign documents and pretend to be the authorized user. Both the holders of a digital certificate and the issuing authority must protect the computers, storage devices, or whatever they use to keep the private keys.
