Security Architecture Documentation
Overview
This document details the security architecture, measures, and best practices implemented in the RecceLabs LLM Dashboard. It covers authentication flows, data protection, infrastructure security, and monitoring practices.
Authentication Flow
1. Initial Authentication
- User submits credentials (email/password) via login form
- Backend validates credentials against MongoDB
- Upon successful validation:
- User data stored in localStorage for client-side access
- Authentication token (base64 encoded user data) set in HTTP-only cookie
- Token includes username and email information
- Cookie set with 7-day expiration
2. Route Protection (Next.js Middleware)
- Middleware intercepts all requests to protected routes
- Checks for presence of 'auth-token' cookie
- Public routes (
/,/login) accessible without authentication - Authenticated users redirected from public routes to
/dashboard - Unauthenticated users redirected to login page
- Route matcher configured for specific paths (
/,/dashboard/:path*)
3. Session Management
- Cookie-based session tracking
- Server-side validation of auth token
- Automatic session expiration after 7 days
- Client-side state management with localStorage
Security Measures
1. Authentication & Authorization
- JWT-based token authentication
- HTTP-only cookies for token storage
- Role-based access control (root/member roles)
- Protected route middleware
- Session timeout mechanisms
- Secure password handling
2. Data Protection
- Input validation using Zod schema
- Email format verification
- Password length restrictions
- Form data sanitization
- Case normalization for emails
- Trimmed input values
3. Frontend Security
- Client-side form validation
- Error message sanitization
- Loading state management
- Protected route navigation
- Secure credential handling
- CSRF protection via tokens
4. API Security
- Request validation
- Error handling and logging
- Rate limiting
- CORS protection
- Request size limits
- Secure headers
5. Infrastructure Security
- Container isolation
- Environment variable protection
- Nginx reverse proxy
- SSL/TLS termination
- Network segmentation
- Service-specific ports
6. Error Handling
- Graceful error recovery
- User-friendly error messages
- Secure error logging
- Failed login attempt handling
- Session recovery mechanisms
7. Monitoring & Auditing
- Authentication attempt logging
- Access log monitoring
- Error tracking
- Security event logging
- User activity tracking
- Real-time alerts
Security Best Practices
