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.Satisfies: SRG-OS-000342-GPOS-00133, SRG-OS-000479-GPOS-00224

Check content

Verify the operating system encrypts audit records off-loaded onto a different system or media from the system being audited. To determine if the transfer is encrypted, use the following command: # grep -i enable_krb5 /etc/audisp/audisp-remote.conf enable_krb5 = yes If the value of the "enable_krb5" option is not set to "yes" or the line is commented out, ask the System Administrator to indicate how the audit logs are off-loaded to a different system or media. If there is no evidence that the transfer of the audit logs being off-loaded to another system or media is encrypted, this is a finding.

Fix text

Configure the operating system to encrypt the transfer of off-loaded audit records onto a different system or media from the system being audited. Uncomment the "enable_krb5" option in "/etc/audisp/audisp-remote.conf" and set it with the following line: 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.
