The DBMS, when using PKI-based authentication, must enforce authorized access to the corresponding private key.

Description
The cornerstone of the PKI is the private key used to encrypt or digitally sign information. If the private key is stolen, this will lead to the compromise of the authentication and non-repudiation gained through PKI because the attacker can use the private key to digitally sign documents and can pretend to be the authorized user. Both the holders of a digital certificate and the issuing authority must protect the computers, storage devices, or whatever they use to keep the private keys. All access to the private key of the DBMS must be restricted to authorized and authenticated users. If unauthorized users have access to the DBMS’s private key, an attacker could gain access to the primary key and use it to impersonate the database on the network.

Check Text ( C-40914r1_chk )
Review DBMS configuration to determine whether appropriate access controls exist to protect the DBMS’s private key. If strong access controls do not exist to enforce authorized access to the private key, this is a finding.

Fix Text (F-36391r1_fix)
Implement strong access and authentication controls to protect the database’s private key.
