Fix Recommendation

Configure the audit directory and logs to be protected from unauthorized read access, by setting the correct owner as "root".

Using the path of the directory containing the audit logs (if not specified, the default location is "/var/log/audit/audit.log"), configure the audit directory and log files to be owned by "root" by using the following command:

$ sudo chown -R root /var/log/audit

Check Contents

Verify the audit directory and logs are owned by "root". First, determine where the audit logs are stored with the following command:

$ sudo grep log_file /etc/audit/auditd.conf

log_file = /var/log/audit/audit.log

Using the location of the audit log file (if not specified, the default location is "/var/log/audit/audit.log"), determine if the audit log is owned by "root" using the following command:

$ sudo find /var/log/audit -exec stat -c "%U %n" {} \;

root /var/log/audit
root /var/log/audit/audit.log

If the audit directory and logs are not owned by "root", this is a finding.
