Title

The /etc/group file must not have an extended ACL. (Cat II impact)

Discussion

The /etc/group file is critical to system security and must be protected from unauthorized modification. The group file contains a list of system groups and associated information.

Check Content

Verify /etc/group has no extended ACL. # ls -l /etc/group If the permissions include a '+', the file has an extended ACL. If the file has an extended ACL and it has not been documented with the IAO, this is a finding.

Fix Text

Remove the extended ACL from the file. # setfacl --remove-all /etc/group
