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.

Systems at unsupported versions or releases of an operating system will not receive security updates for new vulnerabilities which leaves them subject to exploitation. Systems must be maintained at a version of the operating system supported by the vendor with new security updates.
Checks: C-64123r1_chk

Support for the initial release of Windows 8 ended 12 January 2016. After this date, systems must have Windows 8.1 installed. Run "winver.exe". If the "About Windows" dialog box does not display: "Microsoft Windows Version 6.3 (Build 9600)" or greater this is a finding.

Fix: F-69303r2_fix

Update the system to a version of the operating system supported by the vendor. Support for the initial release of Windows 8 ended 12 January 2016. After this date, systems must have Windows 8.1 installed.

Antivirus programs are a primary line of defense against the introduction of viruses and malicious code that can destroy data and even render a computer inoperable. Utilizing an antivirus program provides the ability to detect malicious code before extensive damage occurs. Updated virus scan data files help to protect a system, since new malware are identified by the software vendors on a continual basis.If another recognized antivirus product is installed and has a current signature, this would still be a finding; however, the severity may be reduced to a Category III.
Checks: C-61987r2_chk

If V-19910 from an antivirus STIG has been applied to the system, the signature verification portion of this requirement is NA. Verify a supported DoD antivirus product has been installed on the system. If McAfee VirusScan Enterprise 8.8 Patch 3 or later is not installed on the system, this is a finding. And If a product other than McAfee VirusScan Enterprise is used and V-19910 from an antivirus STIG has not been applied to the system, verify the date of the antivirus signature. If the antivirus program signature has not been updated within the past 7 days, this is a finding. The version numbers and the date of the signature can generally be checked by starting the antivirus program. The information may appear in the antivirus window or be available in the Help >> About window. The location varies from product to product.

Fix: F-66883r1_fix

Install McAfee VirusScan Enterprise 8.8 or later on the system. Update the signature file at least every 7 days.

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).

If an NTP server is configured, it must synchronize with a secure, authorized time source.

Review the following registry values: Registry Hive: HKEY_LOCAL_MACHINE Subkey: \Software\Policies\Microsoft\W32time\Parameters\ Value Name: Type Type: REG_SZ Value: Possible values are NoSync, NTP, NT5DS, AllSync and Value Name: NTPServer Type: REG_SZ Value: "address of the time server" The following would be a finding: "Type" has a value of "NTP" or "Allsync" AND the "NTPServer" value is set to "time.windows.com" or other unauthorized server. The following would not be a finding: The referenced registry values do not exist. "Type" has a value of "NoSync" or "NT5DS". "Type" has a value of "NTP" or "Allsync" AND the "NTPServer" is blank or configured to an authorized time server. For DoD organizations, 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. Domain-joined systems are automatically configured to synchronize with domain controllers, and it would not be a finding unless this is changed.
