Inadequate physical protection can undermine all other security precautions utilized to protect the system. This can jeopardize the confidentiality, availability, and integrity of the system. Physical security is the first line of protection of any system.
Checks: C-44752r1_chk

Verify user workstations containing sensitive data are in access-controlled areas. Users must maintain control of, and protect, mobile systems. If systems are not adequately protected, this is a finding.

Fix: F-41152r1_fix

Establish site policy that ensures workstations containing sensitive data are located inside a controlled access area. Establish a policy on protecting mobile systems outside of controlled areas.

Shared accounts (accounts where two or more people log on with the same user identification) do not provide adequate identification and authentication. There is no way to provide for non-repudiation or individual accountability for system access and resource usage. Documentation must include a list of personnel that have access to each shared account.
Checks: C-44753r3_chk

Determine if any shared accounts exist. If no shared accounts exist, this is NA. Any shared account must be documented with the ISSO. Documentation must include the reason for the account, who has access to this account, and how the risk of using a shared account (which provides no individual identification and accountability) is mitigated. If such documentation does not exist, or is not current, this is a finding. Note: As an example, a shared account may be permitted for a help desk or a site security personnel machine, if that machine is standalone and has no access to the network.

Fix: F-41153r1_fix

Create or update shared accounts documentation that minimally contains the name of the shared account(s), the system(s) on which the accounts exist, and the individuals who have access to the accounts. Remove any shared accounts that do not meet the requirements.

Recovery of a damaged or compromised system in a timely manner is difficult without a system information backup. A system backup will usually include sensitive information such as user accounts that could be used in an attack. As a valuable system resource, the system backup must be protected and stored in a physically secure location.
Checks: C-44757r2_chk

Determine if system recovery backup procedures are in place that comply with DoD requirements. Any of the following would be a finding: -The site does not maintain emergency system recovery data. -The emergency system recovery data is not protected from destruction and stored in a locked storage container. -The emergency system recovery data has not been updated following the last system modification.

Fix: F-41157r1_fix

Implement system recovery procedures that include maintaining emergency system recovery data, protecting that data from destruction and storing it in a locked storage container, and updating it following each and every system modification.

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.

An account that does not have Administrator duties must not have Administrator rights. Such rights would allow the account to bypass or modify required security restrictions on that machine and make it vulnerable to attack. System administrators must log on to systems only using accounts with the minimum level of authority necessary. For domain-joined workstations, the Domain Admins group must be replaced by a domain workstation administrator group (see V-36434 in the Active Directory Domain STIG). Restricting highly privileged accounts from the local Administrators group helps mitigate the risk of privilege escalation resulting from credential theft attacks. Systems dedicated to the management of Active Directory (AD admin platforms, see V-36436 in the Active Directory Domain STIG) are exempt from this. AD admin platforms may use the Domain Admins group or a domain administrative group created specifically for AD admin platforms (see V-43711 in the Active Directory Domain STIG). Standard user accounts must not be members of the local administrators group.

The built-in administrator account, as a well known account subject to attack, is disabled by default and per STIG requirements. Domain administrative accounts on domain-joined systems should provide sufficient availability for administering a system. A site with limited administrators must ensure they have a contingency for administering a non-domain system.
Checks: C-44865r3_chk

Determine if there is a contingency for administering a non-domain system with limited administrators. An emergency administrator account must be documented with the ISSO, and it must be stored with its password in a secure location.

PKU2U is a peer-to-peer authentication protocol. This setting prevents online identities from authenticating to domain-joined systems. Authentication will be centrally managed with Windows user accounts.ECSC-1
Checks: C-45093r2_chk

Analyze the system using the Security Configuration and Analysis snap-in. (See "Performing Analysis with the Security Configuration and Analysis Snap-in" in the STIG Overview document.) Expand the Security Configuration and Analysis tree view. Navigate to Local Policies -&gt; Security Options. If the value for "Network Security: Allow PKU2U authentication requests to this computer to use online identities" is not set to "Disabled", this is a finding. The policy referenced configures the following registry value: Registry Hive: HKEY_LOCAL_MACHINE Subkey: \System\CurrentControlSet\Control\LSA\pku2u\ Value Name: AllowOnlineID Type: REG_DWORD Value: 0

Certain encryption types are no longer considered secure. This setting configures a minimum encryption type for Kerberos, preventing the use of the DES encryption suites.
Checks: C-78965r2_chk

Review the value to the following registry key to verify the DES_CBC_CRC and DES_CBC_MD5 encryption suites are not allowed. 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 "calc". This is the classic Windows calculator not the Windows Store calculator app.) 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.
