SV-90313r1_rule Off-loading audit records to another system must be authenticated.

Vulnerability discussion

Information stored in one location is vulnerable to accidental or incidental deletion or alteration.Off-loading is a common process in information systems with limited audit storage capacity.

Check content

Verify the audit system authenticates off-loading audit records to a different system. Check that the off-loading of audit records to a different system is authenticated with the following command: # sudo grep enable /etc/audisp/audisp-remote.conf enable_krb5 = yes If “enable_krb5” option is not set to "yes" or the line is commented out, this is a finding.

Fix text

Configure the audit system to authenticate off-loading audit records to a different system. Uncomment the "enable_krb5" option in "/etc/audisp/audisp-remote.conf" and set it to "yes". See the example below. enable_krb5 = yes

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.
