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-25725r516555_chk )
Review the logical parmlib data sets, example: SYS1.PARMLIB(IGDSMSxx), for the following SMS parameter settings: Parameter Key SMS ACDS(ACDS data set name) COMMDS(COMMDS data set name) If the required parameters are defined, this is not a finding.

Fix Text (F-25713r516556_fix)
Configure the DFSMS-related PDS members and statements specified in the system parmlib concatenation as outlined below: Parameter Key SMS ACDS(ACDS data set name) COMMDS(COMMDS data set name)
