Description
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.

Who does this work

10 NICE work roles and 9 EC-Council certifications.

This is an inference across published mappings, not a single claim by anyone. This check maps to a control, which maps to a Cybersecurity Framework outcome, which NIST assigns to the work roles below. EC-Council separately maps its certifications to those same roles.

A certification prepares someone for a role. It is not evidence that a holder is qualified, and neither NIST nor EC-Council has stated that any certification here addresses this check.

Work-role assignments published by NIST (NICE Framework Components 2.2.0 and the CSF 2.0 OLIR crosswalk). Certification mappings published by EC-Council.

Check Text (C-272873r1082835_chk)

Review the logical parmlib data sets, example: SYS1.PARMLIB(IGDSMSxx), to identify the fully qualified file names for the following SMS data sets: Active Control Data Set (ACDS) Communications Data Set (COMMDS) If the COMMDS and ACDS SMS data sets identified above reside on different volumes, this is not a finding. If the COMMDS and ACDS SMS data sets identified above are collocated on the same volume, this is a finding.

Fix Text (F-76869r1082834_fix)

Allocate the primary and backup SMS Control data sets on separate volumes. Source Control Data Set (SCDS) contains an SMS configuration, which defines a storage management policy. Active Control Data Set (ACDS) contains a copy of the most recently activated configuration. All systems in an SMS complex use this configuration to manage storage. Communications Data Set (COMMDS) contains the name of the ACDS containing the currently active storage management policy, the current utilization statistics for each system managed volume, and other system information. The ACDS data set will reside on a different volume than the COMMDS data set. Allocate backup copies of the ADCS and COMMDS data sets on a different shared volume from the primary ACDS and COMMDS data sets.
