SECURITY IMPLEMENTATION REPORT - MEAL PREP PLANNER
|
|
|
|
=== AUTHENTICATION & AUTHORIZATION ===
|
|
|
|
✅ IMPLEMENTED:
|
|
1. User registration with email/password
|
|
2. Secure password hashing with bcrypt (cost 12)
|
|
3. Session-based authentication with secure tokens
|
|
4. Session expiry (7 days)
|
|
5. Login/logout functionality
|
|
6. Protected routes with middleware
|
|
7. User data isolation (all queries filtered by user_id)
|
|
|
|
✅ PASSWORD SECURITY:
|
|
- Minimum 8 characters enforced
|
|
- Bcrypt hashing with cost factor 12
|
|
- Password never stored in plain text
|
|
- Password never exposed in JSON responses
|
|
- Passwords compared using constant-time comparison
|
|
|
|
✅ SESSION SECURITY:
|
|
- Cryptographically secure random tokens (32 bytes/256 bits)
|
|
- HttpOnly cookie flag (prevents JavaScript access)
|
|
- SameSite=Strict (CSRF protection)
|
|
- Session expiry enforced in database
|
|
- Expired sessions automatically cleaned up
|
|
- Sessions deleted on logout
|
|
|
|
✅ SQL INJECTION PREVENTION:
|
|
- ALL queries use parameterized statements
|
|
- No string concatenation in SQL
|
|
- Prepared statements throughout
|
|
- User input never directly interpolated
|
|
|
|
✅ XSS PREVENTION:
|
|
- Go html/template auto-escapes all output
|
|
- Input length limits enforced
|
|
- Additional sanitization in auth package
|
|
|
|
✅ USER DATA ISOLATION:
|
|
- Every table has user_id foreign key
|
|
- All queries filter by user_id
|
|
- Users cannot access other users' data
|
|
- Ownership verified before modifications
|
|
- CASCADE deletes maintain referential integrity
|
|
|
|
✅ INPUT VALIDATION:
|
|
- Email format validation
|
|
- Password strength requirements
|
|
- Required field enforcement
|
|
- Type validation (meal types, etc.)
|
|
- Length limits on inputs
|
|
|
|
✅ AUTHORIZATION:
|
|
- Middleware checks session on every request
|
|
- User ID extracted from validated session
|
|
- All handlers receive authenticated user ID
|
|
- No way to forge user identity
|
|
|
|
=== SECURITY MEASURES ===
|
|
|
|
1. PASSWORDS:
|
|
- Hashed with bcrypt (industry standard)
|
|
- Cost factor 12 (good balance)
|
|
- Min 8 characters enforced
|
|
- Never logged or exposed
|
|
|
|
2. SESSIONS:
|
|
- 256-bit random tokens
|
|
- Stored with expiry timestamps
|
|
- Validated on every request
|
|
- Deleted on logout
|
|
- Cannot be forged
|
|
|
|
3. DATABASE:
|
|
- Foreign key constraints
|
|
- User isolation enforced at DB level
|
|
- Parameterized queries only
|
|
- Indexes for performance
|
|
|
|
4. COOKIES:
|
|
- HttpOnly (no XSS access)
|
|
- SameSite=Strict (CSRF protection)
|
|
- Secure flag ready (enable for HTTPS)
|
|
- Proper expiry
|
|
|
|
5. ROUTES:
|
|
- Public: /login, /register
|
|
- Protected: Everything else
|
|
- Middleware enforces authentication
|
|
- Redirects to login if unauthenticated
|
|
|
|
=== CODE REVIEW RESULTS ===
|
|
|
|
✅ auth/auth.go:
|
|
- Secure random token generation
|
|
- Proper bcrypt usage
|
|
- Email validation
|
|
- No hardcoded secrets
|
|
|
|
✅ auth/middleware.go:
|

|
|
- Context-based user ID passing
|
|
- Proper redirects
|
|
- Cookie cleanup
|
|
|
|
✅ database/db.go:
|
|
- ALL queries parameterized
|
|
- User isolation in every query
|
|
- Ownership verification
|
|
- No SQL injection vectors
|
|
|
|
✅ handlers/:
|
|
- All use auth.GetUserID(r)
|
|
- User ID passed to database
|
|
- No direct user input in queries
|
|
- Templates auto-escape
|
|
|
|
=== PRODUCTION RECOMMENDATIONS ===
|
|
|
|
FOR PRODUCTION USE:
|
|
1. ✅ Enable HTTPS (set cookie Secure flag to true)
|
|
2. ✅ Add rate limiting on login/register
|
|
3. ✅ Implement CSRF tokens (currently has SameSite protection)
|
|
4. ✅ Add logging for security events
|
|
5. ✅ Monitor failed login attempts
|
|
6. ✅ Regular security audits
|
|
7. ✅ Keep dependencies updated
|
|
|
|
CURRENT STATUS:
|
