MADB-10-000400 - MariaDB must protect against a user falsely repudiating having performed organization-defined actions.

Information

Nonrepudiation of actions taken is required in order to maintain data integrity. Examples of particular actions taken by individuals include creating information, sending a message, approving information (e.g., indicating concurrence or signing a contract), and receiving a message.

Nonrepudiation protects against later claims by a user of not having created, modified, or deleted a particular data item or collection of data in the database.

In designing a database, the organization must define the types of data and the user actions that must be protected from repudiation. The implementation must then include building audit features into the application data tables and configuring MariaDB's audit tools to capture the necessary audit trail. Design and implementation also must ensure that applications pass individual user identification to MariaDB, even where the application connects to MariaDB with a standard, shared account.

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';
