Check: GEN001400
Title
The /etc/shadow (or equivalent) file must be owned by root. (Cat II impact)
Discussion
The /etc/shadow file contains the list of local system accounts. It is vital to system security and must be protected from unauthorized modification. Failure to give ownership of sensitive files or utilities to root 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 the ownership of the /etc/shadow file. # ls -lL /etc/shadow If the /etc/shadow file is not owned by root, this is a finding.
Fix Text
Change the ownership of the /etc/shadow file. # chown root /etc/shadow
