Secure Database Connections

When your applications connect to a database, sensitive data often travels across the network. Without proper security, this data could be intercepted or tampered with.

• Confidentiality: Prevents unauthorized viewing of data.
• Integrity: Ensures data isn't altered during transit.
• Authentication: Verifies the identity of both client and server.

This lesson focuses on two key methods: SSL/TLS encryption and IP-based access restrictions.

SSL/TLS (Secure Sockets Layer/Transport Layer Security) is the standard technology for establishing an encrypted link between a web server and a client (or in our case, a database server and a client).

• It encrypts all data exchanged, protecting it from eavesdropping.
• It uses digital certificates to verify the identity of the server (and optionally, the client).
• It's crucial for protecting data like passwords, financial details, and personal information during transfer.
