Description
To mitigate the risk of unauthorized access to sensitive information by entities that have been issued certificates by DoD-approved PKIs, all DoD systems (e.g., web servers and web portals) must be properly configured to incorporate access control methods that do not rely solely on the possession of a certificate for access. Successful authentication must not automatically give an entity access to an asset or security boundary. Authorization procedures and controls must be implemented to ensure each authenticated entity also has a validated and current authorization. Authorization is the process of determining whether an entity, once authenticated, is permitted to access a specific asset. Information systems use access control policies and enforcement mechanisms to implement this requirement. Satisfies: SRG-OS-000080-GPOS-00048, SRG-OS-000324-GPOS-00125

Who does this work

17 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-223908r1137691_chk)

The ESM data set rules for SYS1.UADS restricts WRITE or Greater access to only z/OS systems programming personnel. The ESM data set rules for SYS1.UADS restricts READ and/or UPDATE access to z/OS systems programming personnel and/or security personnel. The ESM data set rules for SYS1.UADS specifies that all (i.e., failures and successes) data set access authorities (i.e., READ, UPDATE, ALTER, and CONTROL) will be logged. The ESM data set rules for SYS1.UADS restricts READ access to auditors as documented in Security Plan. If all of the above are untrue, this is not a finding. If any of the above is true, this is a finding.

Fix Text (F-25569r516124_fix)

Evaluate the impact of correcting any deficiency. Develop a plan of action and implement the changes as required to protect SYS1.UADS. SYS1.UADS WRITE or Greater authority is limited to the systems programming staff. Read and update access should be limited to the security staff. READ access is limited to Auditors when included in the site security plan Configure allocate access to SYS1.UADS to be limited to system programmers only, read and update access to SYS1.UADS to be limited to system programmer personnel and/or security personnel and all data set access is logged.
