Security Improvements: - SEC-6: Remove password logging - write to secure file instead - SEC-7: Add CSP headers for XSS prevention - SEC-9: Explicitly configure Argon2id password hashing - SEC-11: Restrict CORS to specific origins (production + localhost) - SEC-12: Implement comprehensive security headers - SEC-13: Explicit JWT expiration enforcement Completed Features: ✓ Password credentials written to .admin-credentials file (600 permissions) ✓ CSP headers prevent XSS attacks ✓ Argon2id explicitly configured (Algorithm::Argon2id) ✓ CORS restricted to connect.azcomputerguru.com + localhost ✓ Security headers: X-Frame-Options, X-Content-Type-Options, etc. ✓ JWT expiration strictly enforced (validate_exp=true, leeway=0) Files Created: - server/src/middleware/security_headers.rs - WEEK1_DAY2-3_SECURITY_COMPLETE.md Files Modified: - server/src/main.rs (password file write, CORS, security headers) - server/src/auth/jwt.rs (explicit expiration validation) - server/src/auth/password.rs (explicit Argon2id) - server/src/middleware/mod.rs (added security_headers) Week 1 Progress: 10/13 items complete (77%) Compilation: SUCCESS (53 warnings, 0 errors) Risk Level: CRITICAL → LOW/MEDIUM Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
