Description
Configuring the operating system to implement organization-wide security implementation guides and security checklists ensures compliance with federal standards and establishes a common security baseline across DoD that reflects the most restrictive security posture consistent with operational requirements. Configuration settings are the set of parameters that can be changed in hardware, software, or firmware components of the system that affect the security posture and/or functionality of the system. Security-related parameters are those parameters impacting the security state of the system, including the parameters required to satisfy other security control requirements. Security-related parameters include, for example: registry settings; account, file, directory permission settings; and settings for functions, ports, protocols, services, and remote connections.

Fix Text (F-25370r514816_fix)
Review all USERIDs with the AU (Manual) - Review all USERIDs with the AUDITOR attribute. Ensure documentation providing justification for access is maintained and filed with the ISSO, and that unjustified access is removed. The AUDITOR attribute is removed from a user with the command: ALU NOAUDITOR. To remove the Group-Auditor attribute: CO GROUP() NOAUDITOR
