Phase 4 Plan 02: Security Filter Chain and Endpoint Protection Summary

Spring Security filter chain with JWT authentication on all protected endpoints, bootstrap token validation on registration, refresh token flow, and 91 passing tests including 18 new security ITs

Performance

• Duration: 26 min
• Started: 2026-03-11T19:11:48Z
• Completed: 2026-03-11T19:38:07Z
• Tasks: 2
• Files modified: 25

Accomplishments

• SecurityFilterChain enforces JWT authentication on all endpoints except health, register, refresh, and docs
• JwtAuthenticationFilter extracts JWT from Authorization header or ?token= query param (SSE support)
• Registration endpoint requires bootstrap token, returns accessToken + refreshToken + serverPublicKey (Ed25519)
• Refresh endpoint issues new access JWT from valid refresh token with agent ID verification
• All 15 existing ITs adapted to use JWT authentication via TestSecurityHelper
• 4 new security ITs (SecurityFilterIT, BootstrapTokenIT, RegistrationSecurityIT, JwtRefreshIT) with 18 tests

Task Commits

Each task was committed atomically:

1. Task 1: SecurityFilterChain + JwtAuthenticationFilter + registration/refresh integration - 387e2e6 (feat)
2. Task 2: Security integration tests + existing test adaptation - 539b85f (test)

Files Created/Modified

• ...security/JwtAuthenticationFilter.java - OncePerRequestFilter extracting JWT from header or query param
• ...security/SecurityConfig.java - SecurityFilterChain with public/protected endpoint split
• ...controller/AgentRegistrationController.java - Updated with bootstrap token validation, JWT issuance, refresh endpoint
• ...config/WebConfig.java - Excluded register/refresh from ProtocolVersionInterceptor
• ...TestSecurityHelper.java - Test utility for JWT-authenticated requests
• ...security/SecurityFilterIT.java - 6 tests for protected/public endpoint access control
• ...security/BootstrapTokenIT.java - 4 tests for bootstrap token validation on registration
• ...security/RegistrationSecurityIT.java - 3 tests for registration security response
• ...security/JwtRefreshIT.java - 5 tests for refresh token flow
• 15 existing IT files updated with JWT authentication headers

Decisions Made

• Added /error to permitAll: Spring Boot forwards exceptions to /error endpoint; without permitting it, controllers returning 404 via ResponseStatusException would result in 403 to the client.
• Excluded register/refresh from ProtocolVersionInterceptor: These are auth/token-renewal endpoints that agents call without full protocol handshake context. Protocol version enforcement is for data/management endpoints.
• Refresh endpoint uses permitAll + self-authentication: The refresh endpoint validates the refresh token directly rather than requiring a separate JWT access token, simplifying the agent token renewal flow.
• SSE query param authentication transparent: JwtAuthenticationFilter checks both Authorization header and ?token= query param, so no SSE controller changes needed.

Deviations from Plan

Auto-fixed Issues

1. [Rule 3 - Blocking] Added /error to SecurityConfig permitAll

• Found during: Task 2 (test execution)
• Issue: Controllers using ResponseStatusException(NOT_FOUND) forward to /error endpoint, which was blocked by Spring Security, resulting in 403 instead of 404
• Fix: Added "/error" to the permitAll requestMatchers list
• Files modified: SecurityConfig.java
• Verification: All 91 tests pass, 404 responses correctly returned

2. [Rule 3 - Blocking] Excluded register/refresh from ProtocolVersionInterceptor

• Found during: Task 2 (JwtRefreshIT tests returning 400)
• Issue: Refresh endpoint matched /api/v1/agents/** interceptor pattern, rejecting requests without X-Cameleer-Protocol-Version header with 400
• Fix: Added /api/v1/agents/register and /api/v1/agents/*/refresh to interceptor excludePathPatterns
• Files modified: WebConfig.java
• Verification: All JwtRefreshIT and BootstrapTokenIT tests pass

---

Total deviations: 2 auto-fixed (2 blocking) Impact on plan: Both fixes necessary for correct Spring Security + Spring MVC interceptor integration. No scope creep.

Issues Encountered

None beyond the auto-fixed blocking issues above.

User Setup Required

None - no external service configuration required.

Next Phase Readiness

• Full Spring Security filter chain active with JWT auth on all protected endpoints
• TestSecurityHelper available for all future integration tests
• Ready for Plan 03: Ed25519 signing of SSE command payloads
• Registration flow complete: bootstrap token -> register -> receive JWT + public key -> use JWT for all API calls -> refresh when expired

Self-Check: PASSED

• All 7 created files verified present on disk
• Both commits (387e2e6, 539b85f) verified in git log
• Full mvn clean verify passed: 91 tests, 0 failures
