Fix Recommendation

Configure data set rules for access to SYSTEM DUMP data set(s) to be limited to system programmers only, unless a letter justifying access is filed with the ISSO in the site security plan.

Evaluate the impact of correcting the deficiency. Develop a plan of action and implement the changes required to restrict access to these data sets.

Check Contents

Refer to data sets SYS1.DUMPxx, additionally, Dump data sets can be identified by reviewing the logical parmlib concatenation data sets for the current COMMNDxx member. Find the COM= which specifies the DUMPDS NAME (DD NAME=name-pattern) entry. The name-pattern is used to identify additional Dump data sets.

If the ESM data set rules for System Dump data sets do not restrict READ, UPDATE, and/or ALTER access to only systems programming personnel, this is a finding.

If the ESM data set rules for all System Dump data sets do not restrict READ access to personnel having justification to review these dump data sets, this is a finding.
