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.

Check Text ( C-97423r1_chk )
From the ISPF Command Shell enter: TSS MODIFY STATUS If the ADSP Control Option value is not set to "ADSP(NO)", this is a finding.

Fix Text (F-104263r1_fix)
Configure the ADSP control option is set to (NO) indicating that the RACF bit in the DSCB will not be set. Evaluate the impact associated with implementation of the control option. Develop a plan of action to implement the control option setting to ADSP(NO) and proceed with the change.
