Fix Recommendation

Configure the SUSE operating system to protect audit rules from unauthorized modification.

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

/var/log/audit root:root 600
/var/log/audit/audit.log root:root 600
/etc/audit/audit.rules root:root 640
/etc/audit/rules.d/audit.rules root:root 640

Set the correct permissions with the following command:

# sudo chkstat --set /etc/permissions.local

Check Contents

Verify that the SUSE operating system protects audit rules from unauthorized modification.

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

# grep -i audit /etc/permissions.local

/var/log/audit root:root 600
/var/log/audit/audit.log root:root 600
/etc/audit/audit.rules root:root 640
/etc/audit/rules.d/audit.rules root:root 640

If the command does not return any output, this is a finding.

Check that all of the audit information files and folders have the correct permissions with the following command:

# sudo chkstat /etc/permissions.local

If the command returns any output, this is a finding.
