The Photon operating system must be configured so the "/etc/cron.allow" file is protected from unauthorized modification.

If cron files and folders are accessible to unauthorized users, malicious jobs may be created.

At the command line, run the following command:

# stat -c "%n permissions are %a and owned by %U:%G" /etc/cron.allow

Expected result:

/etc/cron.allow permissions are 600 and owned by root:root

If the output does not match the expected result, this is a finding.

At the command line, run the following commands:

# chmod 600 /etc/cron.allow
# chown root:root /etc/cron.allow
