The Photon operating system must be configured so that all files have a valid owner and group owner.

If files do not have valid user and group owners, unintended access to files could occur.

At the command line, run the following command:

# find / -fstype ext4 -nouser -o -nogroup -exec ls -ld {} \; 2>/dev/null

If any files are returned, this is a finding.

At the command line, run the following command for each returned file:

# chown root:root <file>
