Vulnerability discussion

Rotate audit logs daily to preserve audit file system space and to conform to the DISA requirement. If it is not rotated daily and moved to another location, then there is more of a chance for the compromise of audit data by malicious users.

Check content

Check for a "logrotate" entry that rotates audit logs. # ls -l /etc/logrotate.d/audit If it exists, check for the presence of the "daily" rotate flag: # egrep "daily" /etc/logrotate.d/audit The command should produce a "daily" entry in the logrotate file for the audit daemon. If the "daily" entry is missing, this is a finding.

Fix text

Create or edit the /etc/logrotate.d/audit file and add the "daily" entry, such as: /var/log/audit/audit.log { compress dateext rotate 15 daily missingok notifempty create 600 root root sharedscripts postrotate /sbin/service auditd restart 2> /dev/null > /dev/null || true endscript }

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
