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.

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.

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-26954r471107_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 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. Implementation guidance for AppLocker is available in the NSA paper "Application Whitelisting using Microsoft AppLocker" at the following link: https://www.iad.gov/iad/library/ia-guidance/tech-briefs/application-whitelisting-using-microsoft-applocker.cfm

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

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-27060r471425_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.

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.

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

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.

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.

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.

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.
