MYS8-00-006100 - The MySQL Database Server 8.0 must uniquely identify and authenticate organizational users (or processes acting on behalf of organizational users) - external authentication plugins

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 in group accounts (e.g., shared privilege accounts) or for detailed accountability of individual activity.

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

Solution

Configure MySQL Database Server 8.0 settings to uniquely identify and authenticate all organizational users who log on/connect to the system.

Remove user-accessible shared accounts and use individual user names.

Configure applications to ensure successful individual authentication prior to shared account access.

Ensure each user's identity is received and used in audit data in all relevant circumstances.

Install appropriate auth plugin, for example LDAP.
INSTALL PLUGIN authentication_ldap_sasl
 SONAME 'authentication_ldap_sasl.so';
INSTALL PLUGIN authentication_ldap_simple
 SONAME 'authentication_ldap_simple.so';

Configure
SET PERSIST authentication_ldap_sasl_server_host='127.0.0.1';
SET PERSIST authentication_ldap_sasl_bind_base_dn='dc=example,dc=com';
SET PERSIST authentication_ldap_simple_server_host='127.0.0.1';
SET PERSIST authentication_ldap_simple_bind_base_dn='dc=example,dc=com';

Create users with proper organizational mapping, for example:
CREATE USER 'betsy'@'localhost'
 IDENTIFIED WITH authentication_ldap_simple
 BY 'uid=betsy_ldap,ou=People,dc=example,dc=com';

Assign appropriate roles and grants.
