Vulnerability discussion

Non-DoD approved PKIs have not been evaluated to ensure that they have security controls and identity vetting procedures in place that are sufficient for DoD systems to rely on the identity asserted in the certificate. PKIs lacking sufficient security controls and identity vetting procedures risk being compromised and issuing certificates that enable adversaries to impersonate legitimate users.The authoritative list of DoD-approved PKIs is published at http://iase.disa.mil/pki-pke/interoperability. DoD-approved PKI CAs may include Category I, II, and III certificates. Category I DoD-approved external PKIs are PIV issuers. Category II DoD-approved external PKIs are Non-Federal Agency PKIs cross-certified with the Federal Bridge Certification Authority (FBCA). Category III DoD-approved external PKIs are Foreign, Allied, or Coalition Partner PKIs.Deploying the ALG with TLS enabled will require the installation of DoD and/or DoD-approved CA certificates in the trusted root certificate store of each proxy to be used for TLS traffic. This requirement focuses on communications protection for the application session rather than for the network packet.

Check content

If Kona Site Defender is providing user authentication intermediary services, confirm that it accepts only end entity certificates issued by DoD PKI or DoD-approved PKI CAs for the establishment of protected sessions: Contact the Akamai Professional Services team to confirm accepted certificate authorities at 1-877-4-AKATEC (1-877-425-2832). If the Akamai Professional Services team confirms that the list of accepted certificate authorities is not issued by DoD-approved PKI certification authorities, this is a finding.

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.
