🔐 Session Hijacking Protection

Multi-Layered Defense

Nube Auth implements a comprehensive 4-layer protection strategy against session hijacking:

Layer 1: Session Fingerprinting

When a session is created, we capture:

• IP Address: The client's IP address
• User-Agent: Browser and OS information

// Session includes fingerprint
interface GatewaySession {
  userId: string;
  appId: string;
  ipAddress?: string;
  userAgent?: string;
  requestCount?: number;
  // ... other fields
}

Layer 2: Fingerprint Validation

On every request, we validate:

• IP address matches original
• User-Agent matches original
• For admin sessions: Strict enforcement (instant logout on mismatch)
• For user sessions: Lenient (logged but allowed for mobile users)

Layer 3: Admin Route Protection

Additional middleware that blocks:

• ❌ Postman, Insomnia, curl, wget
• ❌ Requests without Origin/Referer headers
• ❌ Invalid origins (must be admin domains)
• ❌ Non-browser User-Agents

// Example blocked request
curl -X POST https://api.nubeauth.com/v1/admin/projects \
  -H "Cookie: nube_admin_session=<token>"

// Response: 403 Forbidden
// "Admin operations must be performed through the web interface"

Layer 4: Suspicious Activity Detection

Tracks:

• Request count per session
• IP address changes
• User-Agent changes
• Flags high-volume abuse

Attack Scenarios (All Blocked)

Scenario	Detection	Response
Postman with stolen token	User-Agent contains "Postman"	403 Forbidden
curl with stolen token	User-Agent contains "curl"	403 Forbidden
Different IP address	IP mismatch detected	Session invalidated (admin)
Different browser	Browser/OS change detected	Session invalidated
Missing Origin header	No Origin or Referer	403 Forbidden

🔒 Rate Limiting

Redis-Based Protection

Nube Auth uses a Redis-backed sliding window algorithm for rate limiting:

Auth Endpoints (/v1/auth/*):

• Limit: 10 requests per 5 minutes
• Purpose: Prevent brute-force attacks
• Identifier: User ID (if authenticated) or IP address

API Endpoints (/v1/*):

• Limit: 100 requests per minute
• Purpose: Prevent DoS and abuse
• Identifier: User ID (if authenticated) or IP address

Response Headers

When rate limited, the response includes:

HTTP/1.1 429 Too Many Requests
Retry-After: 180
Content-Type: application/json

{
  "error": "Too Many Requests"
}

🛡️ CSRF Protection

Token-Based Protection

All state-changing operations on admin routes require CSRF tokens:

POST /v1/admin/projects
Origin: https://manage.nubeauth.com
Cookie: nube_admin_session=...
X-Nube-CSRF-Token: ...

Allowed Origins

CSRF tokens are validated against:

• http://localhost:5174 (local admin dashboard)
• https://manage.nubeauth.com (production admin dashboard)
• *.nubeauth.com (any Nube Auth subdomain)

📊 Audit Logging

Event Types

Nube Auth tracks 40+ audit event types:

Authentication Events:

• User login/logout
• OAuth callback
• Session creation/deletion

User Management:

• User invitation
• Role changes
• User deletion

Project/App Management:

• Project creation/update/deletion
• App creation/update/deletion
• Member invitation/removal

Licensing:

• License grant/revoke/renewal
• Plan creation/update/deletion

Payment Configuration:

• Payment provider setup/update
• OAuth provider configuration

Audit Log Format

{
  "id": "AUD0xxxxxxxxx",
  "action": "project.create",
  "userId": 123,
  "projectId": 456,
  "entityType": "project",
  "entityId": 456,
  "oldValue": null,
  "newValue": {
    "projectName": "My Project"

🔍 SQL Injection Protection

Drizzle ORM

Nube Auth uses Drizzle ORM exclusively for all database operations:

✅ Parameterized queries - All user input is parameterized
✅ No raw SQL - No string concatenation of queries
✅ Type-safe - TypeScript ensures query correctness

Verification

A comprehensive scan of the codebase confirmed:

• 0 instances of raw SQL with user input
• 100% coverage with Drizzle ORM
• No string concatenation in queries

🔐 Encryption

AES-256-GCM

All sensitive data is encrypted at rest using AES-256-GCM:

Encrypted Fields:

• OAuth client secrets
• Payment provider credentials
• Webhook secrets
• API keys

Encryption Key:

• 256-bit key (64 hex characters)
• Stored in environment variables
• Rotatable without data loss

# Generate encryption key
node -e "console.log(require('crypto').randomBytes(32).toString('hex'))"

🚨 Security Best Practices

For Administrators

1. Use the Web Dashboard: Always use the admin dashboard for operations
2. Never Share Tokens: Don't share session tokens or cookies
3. Logout When Done: Invalidate sessions after use
4. Use VPN Consistently: Avoid IP changes during sessions
5. Monitor Audit Logs: Review logs regularly for suspicious activity

For Developers

1. Use API Keys: Use API keys for programmatic access (not session tokens)
2. Test Through Browser: Test admin features through the web interface
3. Follow Security Guidelines: Don't bypass security for convenience
4. Report Vulnerabilities: Report security issues immediately

For Security Teams

1. Monitor Logs: Review audit logs for blocked attempts
2. Review Fingerprint Mismatches: Investigate mismatches regularly
3. Check Request Counts: Monitor for high-volume abuse
4. Update Allowed Domains: Keep allowed origins up to date
5. Enhance Detection: Update patterns based on observed attacks
