Thu Jun 13 22:42:10 CST 2024 WARN: Establishing SSL connection without server's identity verification is not recommended. According to MySQL

The message you're referring to is a warning in the MySQL logs, specifically related to establishing an SSL (Secure Sockets Layer) connection without verifying the server's identity. Here's what it means:

When you connect to a MySQL server using SSL, it's important to ensure that you are connecting to a trusted server and not an imposter. The warning "Establishing SSL connection without server's identity verification is not recommended" indicates that the client is attempting to establish a secure connection but isn't verifying the authenticity of the server certificate. This could potentially expose your data to man-in-the-middle attacks.

The reasons for this warning are:

1. Security: Verifying the server's identity ensures that you're connecting to the correct database and not an attacker masquerading as the server. It prevents unauthorized access or eavesdropping.

2. Data Integrity: SSL encryption also provides integrity, meaning that data exchanged between the client and server cannot be tampered with if the certificate is genuine.

To address this warning, you should consider these options:
- Obtain and install the server's trusted certificate, if it's missing or out of date.
- Use SSL/TLS configuration settings that enforce client authentication, so both client and server certificates need to be validated.
- Relax the security settings only when connecting to a trusted development or internal network where such verification is unnecessary.
