How to stop unauthorised connections to MySQL 8?

There are several ways to prevent unauthorized connections to MySQL 8:

  1. User authentication: Requiring a username and password to connect to the database will ensure that only authorized users can access it.
  2. Host-based access control: This allows you to restrict access to the database from specific hosts. You can use the GRANT and REVOKE statements to specify the hosts that are allowed to connect to the database.
  3. Firewall: Setting up a firewall can prevent unauthorized access to your database by blocking incoming connections from specific IP addresses or ranges.
  4. SSL/TLS encryption: Encrypting the connection between the client and the server using SSL or TLS can ensure that the data transmitted is secure and cannot be intercepted by unauthorized users.
  5. Logging: Enabling logging can help you monitor who is connecting to your database and when. You can also set up alerts to notify you of any unauthorized connections.

It is important to follow best security practices and implement multiple layers of security to ensure the safety and protection of your database.
