Fix Recommendation

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 data sets used to backup and/or dump SMF Collection Files.

Configure data set rules for the SMF dump/backup files to restrict WRITE or greater access to authorized DISA and site personnel (e.g., systems programmers and batch jobs that perform SMF processing).
Configure data set rules for the SMF dump/backup files to restrict UPDATE access to others approved the ISSM.
Configure data set rules for the SMF dump/backup files to restrict READ access to authorized auditors and others approved by the ISSM.
Ensure that all update and alter access authority to SMF history files will be logged using the ESM’s facilities.

Check Contents

Obtain the procedures and collection specifics for SMF data sets and backup.

If the ESM data set rules for the SMF dump/backup files do not restrict WRITE or greater access to authorized DISA and site personnel (e.g., systems programmers and batch jobs that perform SMF processing) this is a finding.

If the ESM dataset rules for the SMF dump/backup files do restrict update access as documented in the site security plan this is a finding.

If the ESM data set rules for the SMF dump/backup files do not restrict READ access to auditors and others approved by the ISSM this is a finding.

If the ESM data set rules for SMF dump/backup files do not specify that all (i.e., failures and successes) WRITE or greater access will be logged this is a finding.
