Title

IBM z/OS LOGONID with the ACCTPRIV attribute must be restricted to the ISSO. (Cat II impact)

Discussion

The use of security policy filters provides protection for the confidentiality of data by restricting the flow of data. A crucial part of any flow control solution is the ability to configure policy filters. This allows the operating system to enforce multiple and different security policies. Policy filters serve to enact and enforce the organizational policy as it pertains to controlling data flow.

Check Content

From the ACF Command screen enter: SET LID LIST IF(ACCTPRIV) If logonids with the ACCTPRIV attribute specified are not assigned to the security administrator, this is a finding.

Fix Text

Configure logonids with the ACCTPRIV attribute to be only reserved for use by the Security manager. The ACCTPRIV attribute cannot be scoped, and will be restricted exclusively to a site security administrator: Example: SET LID CHANGE logonid ACCTPRIV
