Description
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 a private key is stolen, an attacker can use it to impersonate the certificate holder. In cases where the database management system (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. All access to the private key(s) of the DBMS must be restricted to authorized and authenticated users.
