Vulnerability discussion

Changes to any software components can have significant effects on the overall security of the network device. Verifying software components have been digitally signed using a certificate that is recognized and approved by the organization ensures the software has not been tampered with and has been provided by a trusted vendor. Accordingly, patches, service packs, or application components must be signed with a certificate recognized and approved by the organization. Verifying the authenticity of the software prior to installation validates the integrity of the patch or upgrade received from a vendor. This ensures the software has not been tampered with and has been provided by a trusted vendor. Self-signed certificates are disallowed by this requirement. The device should not have to verify the software again. This requirement does not mandate DoD certificates for this purpose; however, the certificate used to verify the software must be from an approved CA.

Check content

Determine if the network device prevents the installation of patches, service packs, or application components without verification the software component has been digitally signed using a certificate that is recognized and approved by the organization. This requirement may be verified by demonstration, configuration review, or validated test results. If the network device does not prevent the installation of patches, service packs, or application components without verification the software component has been digitally signed using a certificate that is recognized and approved by the organization, this is a finding.

Fix text

Configure the network device to prevent the installation of patches, service packs, or application components without verification the software component has been digitally signed using a certificate that is recognized and approved by the organization.

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.
