Vulnerability discussion

To prevent unauthorized access or manipulation of system audit logs, the tools for manipulating those logs must be protected.

Check content

Verify the audit tools are group-owned by root, bin, sys, or other. The list of files should minimally include the following: audevent - Change/display event/system call status. audfilter - Load/clear/display the audit filtering policy. auditdp - Selectively read/write and convert/format the audit data. audisp - Display audit records. audomon - Audit file monitoring and size parameter setpoints. audsys - Start/stop auditing; set/display the audit file or directory information. userdbset - Select user to be audited. # ls -lL /usr/sbin/aud* /usr/sbin/userdb* If any system audit tool is not group-owned by root, bin, sys, or other, this is a finding.

Fix text

As root, change the file group ownership. # chgrp root

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.
