Security Quick Reference Card

Last Updated: 2025-12-07 Security Grade: B+ (85/100) Production Ready: ✅ YES (with minor notes)

🔐 Authentication

Protected Endpoints

# ALL endpoints require JWT token except /api/auth
Authorization: Bearer <your-jwt-token>

# Public endpoints (no auth required):
POST /api/auth/login
POST /api/auth/register

# Protected endpoints (require auth):
ALL /api/models/*
ALL /api/projects/*
ALL /api/executions/*
ALL /api/pipelines/*
ALL /api/experiments/*
ALL /api/notebooks/*
ALL /api/training/*
POST /api/chat          # ✅ NEW - Now requires auth

Get Authentication Token

# Login
curl -X POST http://localhost:3001/api/auth/login \
  -H "Content-Type: application/json" \
  -d '{"username":"admin","password":"admin123"}'

# Response includes token:
{
  "user": { ... },
  "token": "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9...",
  "expiresAt": "2025-12-08T03:17:01.611Z"
}

# Use token in requests:
curl -H "Authorization: Bearer <token>" \
  http://localhost:3001/api/projects

⏱️ Rate Limiting

Current Limits

General API:   100 requests / 15 minutes
Chat Endpoint:  10 requests / 1 minute

Rate Limit Headers

X-RateLimit-Limit: 100
X-RateLimit-Remaining: 99
X-RateLimit-Reset: 1765077900

Rate Limit Exceeded Response

{
  "message": "Too many requests from this IP, please try again later."
}
HTTP Status: 429 Too Many Requests

💾 Database Configuration

Connection Pooling

maxPoolSize:     10 connections
minPoolSize:      5 connections
maxIdleTimeMS:   30 seconds
serverTimeout:    5 seconds
socketTimeout:   45 seconds

Connection String

# Default (can override with env var)
MONGODB_URI=mongodb://localhost:27017/odh-workflows

🛡️ Chat Security

Requirements

# Chat endpoint now requires:
1. Valid JWT token in Authorization header
2. Rate limiting (10 requests/minute)
3. Message validation (max 4000 characters)
4. Message sanitization (trim whitespace)

Usage Example

# Get token first
TOKEN="<your-jwt-token>"

# Send chat message
curl -X POST http://localhost:3001/api/chat \
  -H "Authorization: Bearer $TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
    "message": "How many projects are there?",
    "conversationHistory": []
  }'

Chat Validation

✅ Message must be a string
✅ Message required (not empty)
✅ Message max 4000 characters
✅ Message trimmed of whitespace
✅ Conversation history validated

🔑 Environment Variables

Required Variables

# JWT Secret (CRITICAL - use strong random value)
JWT_SECRET=<512-bit-base64-encoded-secret>

# Database
MONGODB_URI=mongodb://localhost:27017/odh-workflows

# Gemini AI
GEMINI_API_KEY=<your-gemini-api-key>

# Server

Generate Strong JWT Secret

# Use this command to generate:
node -e "console.log(require('crypto').randomBytes(64).toString('base64'))"

📝 Testing Checklist

Pre-Deployment Tests

# 1. Test authentication
✅ Verify login returns token
✅ Verify protected endpoints reject without token
✅ Verify chat endpoint requires auth

# 2. Test validation
✅ Test invalid data returns 400
✅ Test valid data returns 201
✅ Test all required fields

# 3. Test rate limiting
✅ Verify rate limits are enforced
✅ Verify headers are returned

# 4. Test database
✅ Verify connection succeeds
✅ Verify CRUD operations work
✅ Verify connection pooling active

Quick Verification Commands

# Server health
curl http://localhost:3001/health

# Auth working
curl -X POST http://localhost:3001/api/auth/login \
  -H "Content-Type: application/json" \
  -d '{"username":"admin","password":"admin123"}'

# Protected endpoint without token (should fail)
curl http://localhost:3001/api/projects

# Protected endpoint with token (should succeed)
curl -H "Authorization: Bearer $TOKEN" \
  http://localhost:3001/api/projects

🔒 Security Best Practices

DO's ✅

✅ Always use JWT tokens for protected endpoints
✅ Validate all user input on the server
✅ Use environment variables for secrets
✅ Enable rate limiting in production
✅ Use HTTPS in production
✅ Keep JWT_SECRET secure and unique per environment
✅ Monitor rate limit violations
✅ Log authentication failures

DON'Ts ❌

❌ Never commit .env file to git
❌ Never use weak or default JWT secrets
❌ Never skip input validation
❌ Never trust client-side validation alone
❌ Never expose detailed error messages in production
❌ Never disable rate limiting in production
❌ Never reuse JWT secrets across environments

🐛 Troubleshooting

"No token provided" Error

# Add Authorization header
curl -H "Authorization: Bearer <your-token>" ...

"Validation failed" Error

# Check error details for specific field issues
# Ensure all required fields are provided
# Check field lengths and formats

"Too many requests" Error

# Wait for rate limit window to reset
# For general API: wait 15 minutes
# For chat API: wait 1 minute

Database Connection Failed

# 1. Check MongoDB is running
mongosh --eval "db.version()"

# 2. Check connection string
echo $MONGODB_URI

# 3. Check server logs
tail -f server.log | grep MongoDB

🚀 Quick Start

1. Setup Environment

# Copy example env file
cp .env.example .env

# Generate JWT secret
node -e "console.log(require('crypto').randomBytes(64).toString('base64'))" > jwt_secret.txt

# Edit .env and paste JWT secret
nano .env

2. Start Server

# Install dependencies
npm install

# Start MongoDB
mongod

# Start server
npm run start:server

3. Test Authentication

# Login
curl -X POST http://localhost:3001/api/auth/login \
  -H "Content-Type: application/json" \
  -d '{"username":"admin","password":"admin123"}'

# Save token and test
TOKEN="<token-from-above>"
