Check: GEN003521

AIX 6.1 SECURITY TECHNICAL IMPLEMENTATION GUIDE: GEN003521 (in versions v1 r14 through v1 r10)

Title

The kernel core dump data directory must be group-owned by bin, sys, or system. (Cat III impact)

Discussion

Kernel core dumps may contain the full contents of system memory at the time of the crash. As the system memory may contain sensitive information, it must be protected accordingly. If the kernel 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

Determine the core file copy location. #sysdumpdev -l | grep -i "core dir" Determine the group owner of the kernel core dump data directory. # ls -lLd < directory > If the group owner is not bin, sys, or system, this is a finding.

Fix Text

Change the group owner of the kernel core dump data directory to bin, sys, or system. # chgrp sys < directory >
