O121-C1-004500 - DBA OS accounts must be granted only those host system privileges necessary for the administration of the DBMS.

Information

This requirement is intended to limit exposure due to operating from within a privileged account or role. The inclusion of role is intended to address those situations where an access control policy, such as Role Based Access Control (RBAC), is being implemented and where a change of role provides the same degree of assurance in the change of access authorizations for both the user and all processes acting on behalf of the user as would be provided by a change between a privileged and non-privileged account.

DBAs, if assigned excessive OS privileges, could perform actions that could endanger the information system or hide evidence of malicious activity.

NOTE: Nessus has not performed this check. Please review the benchmark to ensure target compliance.

Solution

Revoke all host system privileges from the DBA group accounts and DBA user accounts not required for DBMS administration.

Revoke all OS group memberships that assign excessive privileges to the DBA group accounts and DBA user accounts.

Remove any directly applied permissions or user rights from the DBA group accounts and DBA user accounts.

Document all DBA group accounts and individual DBA account-assigned privileges in the System Security Plan.
