MADB-10-003600 - MariaDB must uniquely identify and authenticate organizational users (or processes acting on behalf of organizational users).

Information

To ensure accountability and prevent unauthenticated access, organizational users must be identified and authenticated to prevent potential misuse and compromise of the system.

Organizational users include organizational employees or individuals the organization deems to have equivalent status of employees (e.g., contractors). Organizational users (and any processes acting on behalf of users) must be uniquely identified and authenticated for all accesses, except the following:

(i) Accesses explicitly identified and documented by the organization. Organizations document specific user actions that can be performed on the information system without identification or authentication; and
(ii) Accesses that occur through authorized use of group authenticators without individual authentication. Organizations may require unique identification of individuals using shared accounts, for detailed accountability of individual activity.

It is recommended to not allow shared accounts, including root. The root user is known by all attackers, and often used in attempted attacks on the database servers.

NOTE: Nessus has provided the target output to assist in reviewing the benchmark to ensure target compliance.

Solution

Remove shared accounts which are not documented and have been determined to not be necessary.

MariaDB> DROP USER 'user'@'hostname';
