Fix Recommendation

Configure the SUSE operating system to prevent unauthorized users from accessing system error messages.

Add or update the following rules in "/etc/permissions.local":

/var/log/messages root:root 640

Set the correct permissions with the following command:

> sudo chkstat --set --system

Check Contents

Verify that the SUSE operating system prevents unauthorized users from accessing system error messages.

Check the "/var/log/messages" file permissions with the following comand:

> sudo stat -c "%n %U:%G %a" /var/log/messages

/var/log/messages root:root 640

Check that "permissions.local" file contains the correct permissions rules with the following command:

> grep -i messages /etc/permissions.local

/var/log/messages root:root 640

If the effective permissions do not match the "permissions.local" file, the command does not return any output, or is commented out, this is a finding.
