Security Implementations

1. CSRF (Cross-Site Request Forgery) Protection ✅

What was implemented:

• generateCSRFToken() - Creates 64-character hex tokens with 1-hour expiration
• validateCSRFToken() - Single-use token validation with automatic removal
• cleanupExpiredTokens() - Automatic session cleanup for expired tokens

Coverage:

• 13 HTML form templates now include hidden CSRF tokens
• 12 backend processors validate CSRF before processing
• 1 modal form (campsites.php)
• 1 modal form (bar_tabs.php)

Files Protected:

• All authentication forms (login, register, password reset)
• All booking forms (trips, campsites, courses)
• All user forms (account settings, membership application)
• All community features (comments, bar tabs)
• All payment forms (proof of payment upload)

---

2. Authentication & Session Security ✅

What was implemented:

• Session regeneration after successful login (prevents fixation attacks)
• 30-minute session timeout (prevents unauthorized access)
• HttpOnly, Secure, and SameSite cookie flags
• Password hashing with password_hash() using argon2id algorithm
• Email verification for new user accounts

Security Benefits:

• Session hijacking attacks prevented
• Session fixation attacks prevented
• XSS-based session theft prevented
• CSRF attacks from cross-origin sites prevented
• Inactive session vulnerabilities eliminated

---

3. Rate Limiting & Account Lockout ✅

What was implemented:

• Login attempt tracking in new login_attempts table
• 5 failed attempts → 30-minute account lockout
• Per-IP and per-email tracking
• Automatic unlock after timeout
• Failed attempt reset on successful login

Security Benefits:

• Brute force attacks effectively blocked
• Dictionary attacks prevented
• Credential stuffing attacks mitigated
• Clear audit trail of attack attempts

Audit Logging:

• All login attempts logged (success/failure)
• All account lockouts logged with duration
• All unlocks logged automatically

---

4. SQL Injection Prevention ✅

What was implemented:

• All 100+ database queries converted to prepared statements
• Parameter binding for all user-supplied data
• getResultFromTable() refactored with column/table whitelisting
• Input validation on all form submissions
• Error messages don't reveal database structure

Coverage:

• ✅ Login validation (email/password)
• ✅ Registration (name, email, phone)
• ✅ Booking processing (dates, amounts, IDs)
• ✅ Payment processing (amounts, references)
• ✅ Comment submission (user content)
• ✅ Application forms (personal data)
• ✅ All admin operations

---

5. XSS (Cross-Site Scripting) Prevention ✅

What was implemented:

• Output encoding with htmlspecialchars() on all user data display
• Input validation preventing script injection

• Database sanitization for stored data

Coverage:

• Blog comments display sanitized
• User profile data properly encoded
• Dynamic content generation safe

---

6. File Upload Validation ✅

What was implemented:

• Hardened validateFileUpload() function with:
  • Hardcoded MIME type whitelist per file type

  • Extension validation against whitelist
  • Double extension prevention (e.g., shell.php.jpg blocked)
  • MIME type verification using finfo
  • Image validation with getimagesize()
  • is_uploaded_file() verification
  • Random filename generation (prevents directory traversal)

Recommended Actions Before Deployment

Immediate (Before Go-Live)

1. Delete sensitive files:

   • phpinfo.php (security risk)
   • testenv.php (debug file)
   • Any development/test files

2. Configure deployment settings:

   • Set display_errors = Off in php.ini
   • Set error_reporting = E_ALL
   • Configure error logging to file (not display)
   • Ensure HTTPS enforced on all pages

3. Test the checklist:

   • Execute all 50+ test cases from PHASE_1_SECURITY_TESTING_CHECKLIST.md
   • Document any issues found
   • Create fixes as needed
   • Sign off on all tests

4. Database setup:

   • Run 001_phase1_security_schema.sql migration
   • Verify all tables created
   • Test backup/restore process
   • Configure automated backups

5. Security headers:

   • Add X-Frame-Options: DENY
   • Add X-Content-Type-Options: nosniff
   • Consider Content-Security-Policy header

After Go-Live (Phase 2 - 2-3 weeks later)

1. Implement Web Application Firewall (WAF)
2. Add automated security scanning to CI/CD
3. Set up real-time security monitoring
4. Implement API authentication (JWT/OAuth)
5. Add Content Security Policy (CSP) headers
6. Database connection pooling optimization
7. Performance testing under production load
