Security Summary - Bongo AI

Security Analysis Results

CodeQL Security Scan

Status: All Clear (0 alerts)

  • Date: Latest commit
  • Languages Scanned: JavaScript, TypeScript, GitHub Actions
  • Issues Found: 0
  • Issues Fixed: 7 (GITHUB_TOKEN permissions)

Security Vulnerabilities Fixed

1. GitHub Actions Workflow Permissions

Issue: Missing explicit GITHUB_TOKEN permissions in workflow jobs Risk: Could allow unintended access to repository resources Fix: Added explicit permissions blocks to all workflow jobs with principle of least privilege Files:

  • .github/workflows/ci-cd.yml
  • .github/workflows/security.yml

Permissions Applied:

  • contents: read - For jobs that only need to read repository contents
  • security-events: write - For CodeQL analysis and security scanning results
  • No permissions for deployment jobs (will use deployment-specific tokens)

Security Features Implemented

Authentication & Authorization

✅ JWT-based authentication with secure token management ✅ Bcrypt password hashing (10 rounds) ✅ Refresh token mechanism ✅ Session management with Redis ✅ Token expiration and rotation

API Security

✅ Rate limiting (100 requests per 15 minutes) ✅ CORS configuration with origin whitelisting ✅ Helmet.js security headers (XSS protection, CSP, etc.) ✅ Input validation with Zod schemas ✅ Request sanitization

Data Security

✅ Encryption at rest (database, S3) ✅ Encryption in transit (TLS 1.3) ✅ Secure environment variable handling ✅ No secrets in code or version control ✅ Database connection string security

Infrastructure Security

✅ VPC isolation for services ✅ Security groups with minimal access ✅ Private subnets for databases ✅ Encrypted storage (S3, RDS) ✅ IAM roles with least privilege ✅ Data residency compliance (Bangladesh)

Container Security

✅ Minimal base images (Alpine Linux) ✅ Non-root user execution ✅ No secrets in Dockerfiles ✅ Trivy vulnerability scanning ✅ Regular base image updates

CI/CD Security

✅ Explicit workflow permissions ✅ Dependency vulnerability scanning ✅ CodeQL static analysis ✅ Container image scanning ✅ Secret scanning prevention

Application Security

✅ No SQL injection (parameterized queries) ✅ XSS prevention (input sanitization) ✅ CSRF protection ✅ Secure cookie handling ✅ Error handling without information disclosure

Security Best Practices

Secrets Management

  • ✅ All secrets in environment variables
  • .env file in .gitignore
  • .env.example for documentation
  • ✅ No hardcoded credentials
  • ✅ AWS Systems Manager for production secrets

Monitoring & Logging

  • ✅ Structured logging with Winston
  • ✅ Security event logging
  • ✅ Error tracking (Sentry ready)
  • ✅ Audit trail for sensitive operations
  • ✅ Health check endpoints

Data Privacy

  • ✅ Data residency compliance (Bangladesh)
  • ✅ GDPR-compliant data handling
  • ✅ User consent management
  • ✅ Data minimization
  • ✅ Secure data deletion
