Title

The centralized process core dump data directory must be group-owned by root, bin, or sys. (Cat II impact)

Discussion

Process core dumps contain the memory in use by the process when it crashed. Any data the process was handling may be contained in the core file, and it must be protected accordingly. If the centralized process core dump data directory is not group-owned by a system group, the core dumps contained in the directory may be subject to unauthorized access.

Check Content

Check the defined directory for process core dumps. # coreadm | grep "global core file pattern" Check the group ownership of the directory. # ls -lLd [core file directory] If the directory is not group-owned by root, bin, or sys, this is a finding.

Fix Text

The root role is required. Change the group-owner of the core file directory to root, bin, or sys. Example: # chgrp root [core file directory]
