Spring Security Fundamentals

Before JWT, before roles — every secured request in Spring passes through the same mechanism. This module is that mechanism.

Learning objectives

  • Beginner: State the difference between authentication and authorization in one sentence each.
  • Intermediate: Trace a request through the security filter chain and identify where authentication actually happens.
  • Advanced: Configure a custom SecurityFilterChain bean that intentionally loosens or tightens Spring Security's secure-by-default posture for a specific use case.
