Using a privileged account to perform routine functions makes the computer vulnerable to malicious software inadvertently introduced during a session that has been granted full privileges.
Checks: C-57723r848528_chk

Verify each user with administrative privileges has been assigned a unique administrative account separate from their standard user account. If users with administrative privileges do not have separate accounts for administrative functions and standard user functions, this is a finding.

Fix: F-57674r848529_fix

Ensure each user with administrative privileges has a separate account for user duties and one for privileged duties.

The longer a password is in use, the greater the opportunity for someone to gain unauthorized knowledge of the password. The built-in Administrator account is not generally used and its password may not be changed as frequently as necessary. Changing the password for the built-in Administrator account on a regular basis will limit its exposure. Windows LAPS must be used to change the built-in Administrator account password.
Checks: C-57724r951093_chk

If there are no enabled local Administrator accounts, this is Not Applicable. Review the password last set date for the enabled local Administrator account. On the stand alone or domain-joined workstation: Open "PowerShell". Enter "Get-LocalUser -Name * | Select-Object *". If the "PasswordLastSet" date is greater than "60" days old for the local Administrator account for administering the computer/domain, this is a finding. Verify LAPS is configured and operational. Navigate to Local Computer Policy >> Computer Configuration >> Administrative Templates >> System >> LAPS >> Password Settings >> Set to enabled. Password Complexity, large letters + small letters + numbers + special, Password Length 14, Password Age 60. If not configured as shown, this is a finding. Navigate to Local Computer Policy >> Computer Configuration >> Administrative Templates >> System >> LAPS >> Password Settings >> Name of administrator Account to manage >> Set to enabled >> Administrator account name is populated. If it is not, this is a finding. Verify LAPS Operational logs >> Event Viewer >> Applications and Services Logs >> Microsoft >> Windows >> LAPS >> Operational. Verify LAPS policy process is completing. If it is not, this is a finding.

Fix: F-57675r951094_fix

Change the enabled local Administrator account password at least every 60 days. Windows LAPS must be used to change the built-in Administrator account password. Domain-joined systems can configure this to occur more frequently. LAPS will change the password every 30 days by default.

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 require administrative accounts to not access the internet or use applications such as email. The policy must 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. Whitelisting can be used to enforce the policy to ensure compliance. Satisfies: SRG-OS-000480-GPOS-00227, SRG-OS-000205-GPOS-00083
Checks: C-57725r848534_chk

Determine whether organization policy, at a minimum, 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. If it does not, this is a finding. The organization may use technical means such as whitelisting to prevent the use of browsers and mail applications to enforce this requirement.

Fix: F-57676r848535_fix

Establish a policy, at minimum, to prohibit administrative accounts from using applications that access the internet, such as web browsers, or with potential internet sources, such as email. Ensure the policy is enforced. The organization may use technical means such as whitelisting to prevent the use of browsers and mail applications to enforce this requirement.

b

Backup Operators are able to read and write to any file in the system, regardless of the rights assigned to it. Backup and restore rights permit users to circumvent the file access restrictions present on NTFS disk drives for backup and restore purposes. Members of the Backup Operators group must have separate logon accounts for performing backup duties.
Checks: C-57726r848537_chk

If no accounts are members of the Backup Operators group, this is NA. Verify users with accounts in the Backup Operators group have a separate user account for backup functions and for performing normal user tasks. If users with accounts in the Backup Operators group do not have separate accounts for backup functions and standard user functions, this is a finding.

Fix: F-57677r848538_fix

Ensure each member of the Backup Operators group has separate accounts for backup functions and standard user functions.

Application/service account passwords must be of sufficient length to prevent being easily cracked. Application/service accounts that are manually managed must have passwords at least 14 characters in length.
Checks: C-57727r951096_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 14 characters in length. If such a policy does not exist or has not been implemented, this is a finding.

Fix: F-57678r951097_fix

Establish a policy that requires application/service account passwords that are manually managed to be at least 14 characters in length. Ensure the policy is enforced.

Setting application account passwords 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-57728r848543_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 "PowerShell". Enter "Get-AdUser -Identity [application account name] -Properties PasswordLastSet | FT 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 or nondomain-joined systems: Open "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.

Fix: F-57679r848544_fix

Change passwords for manually managed application/service accounts at least annually or when an administrator with knowledge of the password leaves the organization. It is recommended that system-managed service accounts be used whenever possible.

Checks: C-57729r848546_chk

Determine whether any shared accounts exist. If no shared accounts exist, this is NA. Shared accounts, such as required by an application, may be approved by the organization. This must be documented with the Information System Security Officer (ISSO). Documentation must include the reason for the account, who has access to the account, and how the risk of using the shared account is mitigated to include monitoring account activity. If unapproved shared accounts exist, this is a finding.

Fix: F-57680r848547_fix

Remove unapproved shared accounts from the system. Document required shared accounts with the ISSO. Documentation must include the reason for the account, who has access to the account, and how the risk of using the shared account is mitigated to include monitoring account activity.

Using an allowlist provides a configuration management method to allow 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-57730r890534_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 in to Windows Server. 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 imported previously, 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.

Credential Guard uses virtualization-based security to protect data that could be used in credential theft attacks if compromised. A number of system requirements must be met in order for Credential Guard to be configured and enabled properly. Without a TPM enabled and ready for use, Credential Guard keys are stored in a less secure method using software.
Checks: C-57731r848552_chk

For standalone or nondomain-joined systems, this is NA. Verify the system has a TPM and it is ready for use. Run "tpm.msc". Review the sections in the center pane. "Status" must indicate it has been configured with a message such as "The TPM is ready for use" or "The TPM is on and ownership has been taken". TPM Manufacturer Information - Specific Version = 2.0 or 1.2 If a TPM is not found or is not ready for use, this is a finding.

Fix: F-57682r848553_fix

Ensure domain-joined systems have a TPM that is configured for use. (Versions 2.0 or 1.2 support Credential Guard.) The TPM must be enabled in the firmware. Run "tpm.msc" for configuration options in Windows.

A properly configured Host-based Intrusion Detection System (HIDS) or Host-based Intrusion Prevention System (HIPS) provides another level of defense against unauthorized access to critical servers. With proper configuration and logging enabled, such a system can stop and/or alert for many attempts to gain unauthorized access to resources.
Checks: C-57734r848561_chk

Determine whether there is a HIDS or HIPS on each server. If the HIPS component of ESS is installed and active on the host and the alerts of blocked activity are being logged and monitored, this meets the requirement. A HIDS device is not required on a system that has the role as the Network Intrusion Device (NID). However, this exception needs to be documented with the Information System Security Officer (ISSO). If a HIDS is not installed on the system, this is a finding.

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.

Emergency administrator accounts are privileged accounts 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 must 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-57753r848618_chk

Determine if emergency administrator accounts are used and identify any that exist. If none exist, this is NA. If emergency administrator accounts cannot be configured with an expiration date due to an ongoing crisis, the accounts must be disabled or removed when the crisis is resolved. If emergency administrator accounts have not been configured with an expiration date or have not been disabled or removed following the resolution of a crisis, this is a finding. Domain Controllers: Open "PowerShell". Enter "Search-ADAccount -AccountExpiring | FT Name, AccountExpirationDate". If "AccountExpirationDate" has been defined and is not within 72 hours for an emergency administrator account, this is a finding. Member servers and standalone or nondomain-joined systems: Open "Command Prompt". Run "Net user [username]", where [username] is the name of the emergency account. If "Account expires" has been defined and is not within 72 hours for an emergency administrator account, this is a finding.

Fix: F-57704r848619_fix

Remove emergency administrator accounts after a crisis has been resolved or configure the accounts to automatically expire within 72 hours. Domain accounts can be configured with an account expiration date, under "Account" properties. Local accounts can be configured to expire with the command "Net user [username] /expires:[mm/dd/yyyy]", where [username] is the name of the temporary user account.

In Kerberos, there are two 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 start up under a specified user account, users must always get a TGT first and then get Service Tickets to all computers and services accessed.

When directory service database objects do not have appropriate access control permissions, it may be possible for malicious users to create, read, update, or delete the objects and degrade or destroy the integrity of the data. When the directory service is used for identification, authentication, or authorization functions, a compromise of the database objects could lead to a compromise of all systems relying on the directory service. For Active Directory (AD), the Group Policy objects require special attention. In a distributed administration model (i.e., help desk), Group Policy objects are more likely to have access permissions changed from the secure defaults. If inappropriate access permissions are defined for Group Policy objects, this could allow an intruder to change the security policy applied to all domain client computers (workstations and servers).

When directory service database objects do not have appropriate access control permissions, it may be possible for malicious users to create, read, update, or delete the objects and degrade or destroy the integrity of the data. When the directory service is used for identification, authentication, or authorization functions, a compromise of the database objects could lead to a compromise of all systems that rely on the directory service. For Active Directory, the OU objects require special attention. In a distributed administration model (i.e., help desk), OU objects are more likely to have access permissions changed from the secure defaults. If inappropriate access permissions are defined for OU objects, it could allow an intruder to add or delete users in the OU. This could result in unauthorized access to data or a denial of service (DoS) to authorized users.

When directory service data files, especially for directories used for identification, authentication, or authorization, reside on the same logical partition as user-owned files, the directory service data may be more vulnerable to unauthorized access or other availability compromises. Directory service and user-owned data files sharing a partition may be configured with less restrictive permissions in order to allow access to the user data. The directory service may be vulnerable to a denial of service attack when user-owned files on a common partition are expanded to an extent preventing the directory service from acquiring more space for directory or audit data.

Executing application servers on the same host machine with a directory server may substantially weaken the security of the directory server. Web or database server applications usually require the addition of many programs and accounts, increasing the attack surface of the computer. Some applications require the addition of privileged accounts, providing potential sources of compromise. Some applications (such as Microsoft Exchange) may require the use of network ports or services conflicting with the directory server. In this case, nonstandard ports might be selected, and this could interfere with intrusion detection or prevention services.

In the Search dialog, enter the DN of the domain naming context (generally something like "dc=disaost,dc=mil") in the Base DN field. Clear the Attributes field and select "Run". Error messages must display related to Bind and user not authenticated. If attribute data is displayed, anonymous access is enabled to the domain naming context and this is a finding. The following network controls allow the finding severity to be downgraded to a CAT II since these measures lower the risk associated with anonymous access. Network hardware ports at the site are subject to 802.1x authentication or MAC address restrictions. Premise firewall or host restrictions prevent access to ports 389, 636, 3268, and 3269 from client hosts not explicitly identified by domain (.mil) or IP address.

Configure directory data (outside the root DSE) of a nonpublic directory to prevent anonymous access. For AD, there are multiple configuration items that could enable anonymous access. Changing the access permissions on the domain naming context object (from the secure defaults) could enable anonymous access. If the check procedures indicate this is the cause, the process that was used to change the permissions must be reversed. This could have been through the Windows Support Tools ADSI Edit console (adsiedit.msc). The dsHeuristics option is used. This is addressed in check V-8555 in the AD Forest STIG.

The failure to terminate inactive network connections increases the risk of a successful attack on the directory server. The longer an established session is in progress, the more time an attacker has to hijack the session, implement a means to passively intercept data, or compromise any protections on client access. For example, if an attacker gains control of a client computer, an existing (already authenticated) session with the directory server could allow access to the directory. The lack of confidentiality protection in LDAP-based sessions increases exposure to this vulnerability. Satisfies: SRG-OS-000163-GPOS-00072, SRG-OS-000279-GPOS-00109

When inappropriate audit settings are configured for directory service database objects, it may be possible for a user or process to update the data without generating any tracking data. The impact of missing audit data is related to the type of object. A failure to capture audit data for objects used by identification, authentication, or authorization functions could degrade or eliminate the ability to track changes to access policy for systems or data. For Active Directory (AD), there are a number of critical object types in the domain naming context of the AD database for which auditing is essential. This includes the Domain Controller OU object. Because changes to these objects can significantly impact access controls or the availability of systems, the absence of auditing data makes it impossible to identify the source of changes that impact the confidentiality, integrity, and availability of data and systems throughout an AD domain.

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 could cause a client to make decisions based on false records from the LDAP directory. The risk of an attacker pulling this off can be decreased 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.

The krbtgt account acts as a service account for the Kerberos Key Distribution Center (KDC) service. The account and password are created when a domain is created and the password is typically not changed. If the krbtgt account is compromised, attackers can create valid Kerberos Ticket Granting Tickets (TGT). The password must be changed twice to effectively remove the password history. Changing once, waiting for replication to complete and the amount of time equal to or greater than the maximum Kerberos ticket lifetime, and changing again reduces the risk of issues.

Reset the password for the krbtgt account a least every 180 days. The password must be changed twice to effectively remove the password history. Changing once, waiting for replication to complete and changing again reduces the risk of issues. Changing twice in rapid succession forces clients to re-authenticate (including application services) but is desired if a compromise is suspected. PowerShell scripts are available to accomplish this such as at the following link: https://gallery.technet.microsoft.com/Reset-the-krbtgt-account-581a9e51 Open "Active Directory Users and Computers" (available from various menus or run "dsa.msc"). Select "Advanced Features" in the "View" menu if not previously selected. Select the "Users" node. Right-click on the krbtgt account and select "Reset password". Enter a password that meets password complexity requirements. Clear the "User must change password at next logon" check box.

For domain-joined member servers, the Domain Admins group must be replaced by a domain member server administrator group (see V-243468 in the Active Directory Domain STIG).
