Check: GEN001820

IRIX 6.5: GEN001820 (in versions v1 r1 through v1 r0.6)

Title

All skeleton files and directories (typically in /etc/skel) must be owned by bin. (Cat II impact)

Discussion

If the skeleton files are not protected, unauthorized personnel could change user startup parameters and possibly jeopardize user files. Failure to give ownership of sensitive files or utilities to bin provides the designated owner and unauthorized users with the potential to access sensitive information or change the system configuration which could weaken the system's security posture.

Check Content

Check skeleton files ownership. # find /etc/skel -name * ! -user bin -exec ls -alL {} \; 2>/dev/null If a skeleton file is not owned by bin, this is a finding.

Fix Text

Change the ownership of skeleton files with incorrect mode. # chown bin <skeleton file>
