Security Documentation

Overview

This document outlines the comprehensive security measures implemented in the Bootstrap App. The application follows industry best practices and security standards to protect against common threats and vulnerabilities.

Security Architecture

Defense in Depth

The application implements multiple layers of security:

1. Network Security: HTTPS, CORS, security headers
2. Authentication: JWT token-based authentication
3. Authorization: Role-based access control (RBAC)
4. Input Security: Validation, sanitization, size limits
5. Data Security: Encryption, secure storage
6. Monitoring: Audit logging, security event tracking
7. Infrastructure: Secure deployment practices

Authentication System

JWT (JSON Web Tokens)

Implementation:

• RS256/HS256 signing algorithms
• Configurable token expiration (default: 24 hours access, 7 days refresh)
• Secure token storage and transmission
• Token revocation support

Security Features:

• Cryptographically secure secret generation
• Token payload minimization
• Automatic token expiration
• Refresh token rotation

Configuration:

JWT_SECRET=base64-encoded-secret-64-bytes
JWT_ACCESS_TTL_HOURS=24
JWT_REFRESH_TTL_DAYS=7
JWT_ISSUER=omega-server

Password Security

Hashing:

• bcrypt with cost factor 12
• Salt automatically generated per password
• Resistant to rainbow table attacks

Password Policy:

• Minimum 8 characters
• Must contain uppercase, lowercase, number, special character
• Common password detection
• Password strength scoring (0-100)

Additional Security:

• Account lockout after failed attempts
• Password history prevention
• Secure password reset flow

Authorization System

Role-Based Access Control (RBAC)

Components:

• Users: Individual user accounts
• Roles: Collections of permissions (admin, user, viewer)
• Permissions: Granular access rights (user:create, user:read, etc.)

Permission Format:

resource:action
Examples: user:create, role:delete, system:admin

Default Roles:

• admin: Full system access
• user: Standard user privileges
• viewer: Read-only access

Permission Checking

Implementation:

// Middleware-based permission checking
app.Get("/api/v1/users", authMW.HasPermission("user:read"), controller.GetUsers)

// Service-level permission checking
if !user.HasPermission("user:create") {
    return errors.New("insufficient permissions")
}

Strict-Transport-Security: max-age=31536000; includeSubDomains; preload
Content-Security-Policy: default-src 'self'
Referrer-Policy: strict-origin-when-cross-origin

Rate Limiting

Multi-Layer Rate Limiting

Global Rate Limiting:

• 100 requests per minute per IP
• Configurable limits per endpoint
• Token bucket algorithm

Authentication Rate Limiting:

• 5 login attempts per 15 minutes
• Progressive delays for failed attempts
• Account lockout protection

API Rate Limiting:

• Per-user rate limits
• Per-endpoint specific limits
• Burst capacity handling

Implementation

// Global rate limiting
app.Use(securityMW.RateLimit(100, 1*time.Minute))

// Authentication rate limiting
app.Post("/auth/login", securityMW.AuthRateLimit(), authController.Login)

Data Protection
