IBM z/OS must limit access for SMF collection files (i.e., SYS1.MANx) to appropriate users and/or batch jobs that perform SMF dump processing.

Description
SMF data collection is the system activity journaling facility of the z/OS system. Unauthorized access could result in the compromise of logging and recording of the operating system environment, ESM, and customer data. Unauthorized disclosure of audit records can reveal system and configuration data to attackers, thus compromising its confidentiality. Audit information includes all information (e.g., audit records, audit settings, audit reports) needed to successfully audit operating system activity.

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-223881r958434_chk)

Refer to the SMFPRMxx member in SYS1.PARMLIB. Determine the SMF and/or Logstream data set name. If the following statements are true, this is not a finding. -The ESM data set rules for the SMF data collection files (e.g., SYS1.MAN* or IFASMF.SYS1.*) restrict ALTER access to only z/OS systems programming personnel. -The ESM data set rules for the SMF data collection files (e.g., SYS1.MAN* or IFASMF.SYS1.*) restrict UPDATE access to z/OS systems programming personnel, and/or batch jobs that perform SMF dump processing and others as approved by ISSM. -The ESM data set rules for the SMF data collection files (e.g., SYS1.MAN* or IFASMF.SYS1.*) restrict READ access to auditors and others approved by the ISSM. -The ESM data set rules for SMF data collection files (e.g., SYS1.MAN* or IFASMF.SYS1.*) specify that all (i.e., failures and successes) UPDATE and/or ALTER access are logged.

Fix Text (F-25542r516756_fix)

Ensure that allocate/alter authority to SMF collection files is limited to only systems programming staff and and/or batch jobs that perform SMF dump processing; access can be granted to others as determined by ISSM. Ensure that read access is limited to auditors. Access may be granted to others as determined by the ISSM. Ensure the accesses are being logged. Ensure that all (i.e., failures and successes) WRITE or greater access are logged. Ensure read access failures are logged.
