Logging and Monitoring Security Events

Security logging is like having a digital security camera for your application. It records important events, helping you understand what's happening within your system.

These logs are crucial for detecting malicious activities, troubleshooting issues, and meeting compliance requirements. Without proper logging, it's nearly impossible to know if your system is under attack or has been compromised.

Spring Security publishes various events when something significant happens, especially during authentication and authorization. These events are part of Spring's ApplicationEvent system.

• Authentication Events: Fired during login attempts (success, failure).
• Authorization Events: Fired when access is granted or denied to resources.
• Session Events: Fired when sessions are created or destroyed.

By listening to these events, we can capture detailed security information.
