Information
MariaDB must disable network functions, ports, protocols, and services deemed by the organization to be nonsecure, in accord with the Ports, Protocols, and Services Management (PPSM) guidance.
GROUP ID: V-253734
RULE ID: SV-253734r961470
Use of nonsecure network functions, ports, protocols, and services exposes the system to avoidable threats.
Solution
To verify that mariadb system denies specific network functions, locate cnf file and specifically bind ip address to deny (or port):
$ ls -la /etc | grep my.cnf
-rw-r--r--. 1 root root 301 Aug 25 12:45 my.cnf
bind-address = 127.0.0.1 #just an example
To specifically change default port (3306) is something different:
port = 1234
bind = 10.10.10.10 #as an example
After making changes to the .cnf file, stop and restart the database service.
