✨ What's Included in Phase 2

🔐 Four Security Features Implemented

1. CSRF Token Protection

  • Prevents cross-site request forgery attacks
  • Applied to 9 forms and 10 processors
  • File: src/Middleware/CsrfMiddleware.php

2. Rate Limiting

  • Blocks brute force login attempts (5 per 15 minutes)
  • Blocks password reset abuse (3 per 30 minutes)
  • File: src/Middleware/RateLimitMiddleware.php

3. Session Regeneration

  • Prevents session fixation attacks
  • Integrated with existing login flow
  • File: Phase 1 AuthenticationService (enhanced)

4. Audit Logging

  • Complete login audit trail
  • Captures email, IP, timestamp, failure reason
  • File: src/Services/AuditLogger.php
  • Database: migrations/001_create_audit_logs_table.sql

📦 What You Have

✅ Verification Checklist

Before deploying, verify you have:

  • All 6 documentation files present in root directory
  • src/Middleware/CsrfMiddleware.php exists (3.2 KB)
  • src/Middleware/RateLimitMiddleware.php exists (9.3 KB)
  • src/Services/AuditLogger.php exists (12.6 KB)
  • migrations/001_create_audit_logs_table.sql exists
  • Git branch is feature/site-restructure
  • All 10 Phase 2 commits visible in git log
  • Database backup completed

If all checked ✅ you're ready to deploy!

🎯 Expected Deployment Time

Phase Duration Notes
Pre-deployment 10 min Backup + quick review
Database migration 2-5 min Run SQL migration script
Code deployment 5 min Pull/merge code
Testing & verification 30-45 min Follow DEPLOYMENT_CHECKLIST.md
Post-deployment monitoring 24 hours Monitor error logs + audit_logs
Total time to production ~1 hour (spread across 24-48 hours)

🔄 Rollback Plan

If something goes wrong, you can easily rollback:

Option 1: Drop Audit Logs Table (Recommended)

DROP TABLE audit_logs;
  • Removes audit logging only
  • Site continues working normally
  • Takes 1 minute

Option 2: Revert Code Only

git revert <commit-hash>
  • Code reverts to before Phase 2
  • Database stays updated
  • Takes 5 minutes

Option 3: Full Rollback

  • Restore database from backup
  • Revert code to previous commit
  • Takes 10-15 minutes

📞 Getting Help

Most Common Questions

Q: Will this break existing functionality?
A: No. Phase 2 is 100% backward compatible.

Q: What if rate limiting blocks legitimate users?
A: The block automatically resets after the time window (15-30 minutes).

Q: How much storage will audit logging use?
A: About 100-200 MB per year. Negligible.

Q: Can I adjust rate limiting thresholds?
A: Yes, see PHASE2_COMPLETE.md for configuration.
