Vulnerability discussion

The DoD standard for authentication is DoD-approved PKI certificates. PKI certificate-based authentication is performed by requiring the certificate holder to cryptographically prove possession of the corresponding private key.If the private key is stolen, an attacker can use the private key(s) to impersonate the certificate holder. In cases where the DBMS-stored private keys are used to authenticate the DBMS to the system’s clients, loss of the corresponding private keys would allow an attacker to successfully perform undetected man in the middle attacks against the DBMS system and its clients.Both the holder of a digital certificate and the issuing authority must take careful measures to protect the corresponding private key. Private keys should always be generated and protected in FIPS 140-2 validated cryptographic modules.All access to the private key(s) of the DBMS must be restricted to authorized and authenticated users. If unauthorized users have access to one or more of the DBMS's private keys, an attacker could gain access to the key(s) and use them to impersonate the database on the network or otherwise perform unauthorized actions.

Check content

Review DBMS configuration to determine whether appropriate access controls exist to protect the DBMS's private key(s). If the DMBS’s private key(s) are not stored in a FIPS 140-2 validated cryptographic module, this is a finding. If access to the DBMS’s private key(s) is not restricted to authenticated and authorized users, this is a finding.

Fix text

Store all DBMS PKI private keys in a FIPS 140-2 validated cryptographic module. Ensure access to the DBMS PKI private keys is restricted to only authenticated and authorized users.

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.
