CA-TSS must limit access to data sets used to back up and/or dump SMF collection files to appropriate users and/or batch jobs that perform SMF dump processing.
An XCCDF Rule
Description
<VulnDiscussion>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.

Remediation - Manual Procedure
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.
