Description
Access control policies include: identity-based policies, role-based policies, and attribute-based policies. Access enforcement mechanisms include: access control lists, access control matrices, and cryptography. These policies and mechanisms must be employed by the application to control access between users (or processes acting on behalf of users) and objects (e.g., devices, files, records, processes, programs, and domains) in the information system.

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.

From the ISPF Command Shell, enter: LISTCat USERCATALOG NAME NOPREFIX Review the ACF2 data set rules for each usercatalog defined. If the data set rules for User Catalogs do not restrict ALLOCATE access to only z/OS systems programming personnel, this is a finding. If products or procedures requiring system programmer access for system-level maintenance meet the following specific case: - The batch job or procedure must be documented in the SITE Security Plan. - Reside in a data set that is restricted to systems programmers' access only. If the above is true, this is not a finding. If the data set rules for User Catalogs do not specify that all (i.e., failures and successes) ALLOCATE access will be logged, this is a finding. Note: If the USER CATALOGS contain SMS managed data sets, READ access is sufficient to allow user operations. If the USER CATALOGS do not contain SMS managed datasets, WRITE access is required for user operation.

Fix Text (F-25096r918578_fix)

Review access authorization to critical system files. Evaluate the impact of correcting the deficiency. Develop a plan of action and implement the changes as required to protect USER CATALOGS. Configure ACF2 rules for allocate access to USER CATALOGS, limited to system programmers only, and all allocate access is logged. Configure ACF2 rules for the USER CATALOGS to allow any Products or procedures system programmer access for system-level maintenance that meets the following specific case: - The batch job or procedure must be documented in the SITE Security Plan. - Reside in a data set that is restricted to systems programmers' access only. Note: If the USER CATALOGS contain SMS managed data sets READ access is sufficient to allow user operations. If the USER CATALOGS do not contain SMS managed datasets WRITE access is required for user operation.
