High |
The DBMS must obscure feedback of authentication information during the authentication process to protect the information from possible exploitation/use by unauthorized individuals. |
The DoD standard for authentication is DoD-approved PKI certificates.

The DBMS must enforce authorized access to all PKI private keys stored/utilized by the DBMS. |
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... |

High |
The DBMS must enforce approved authorizations for logical access to information and system resources in accordance with applicable access control policies. |
Authentication with a DoD-approved PKI certificate does not necessarily imply authorization to access the DBMS. To mitigate the risk of unauthorized access to sensitive information by entities that have been issued certificates by DoD-approved PKIs, all DoD systems, including databases, must be properly configured to implement access control policies.

The DBMS must integrate with an organization-level authentication/access mechanism providing account management and automation for all users, groups, roles, and any other principals. |
Enterprise environments make account management for applications and databases challenging and complex. A manual process for account management functions adds the risk of a potential oversight or other error. Managing accounts for the same person in multiple places is inefficient and prone to problems with consistency and synchronization.
