One thing to look at
- 0 stars0 stars. Stars are a popularity signal and not a quality one, but at this level it is likely that nobody has read this closely except its author, and you would be relying on your own review.

MONOPOLY — Security Hardening Checklist
Network Security
- All services inside private VPC; only LB/API GW exposed publicly
- Security groups follow least-privilege (deny all, allow specific ports/CIDRs)
- NACLs as secondary defense layer
- WAF enabled with OWASP top 10 ruleset
- DDoS protection (Cloudflare / AWS Shield Standard minimum)
- VPN or Private Link for inter-service communication in multi-region
Authentication & Authorization
- JWT tokens with short expiry (15 min access, 7 day refresh)
- OAuth 2.0 / OIDC for third-party auth
- MFA enforced for admin accounts
- RBAC or ABAC for authorization
- No secrets in JWT payload (use opaque references)
- Token revocation strategy (Redis blocklist or short TTL)
API Security
- Rate limiting at API gateway (per user, per IP, per endpoint)
- Input validation and sanitization on all endpoints
- SQL injection prevention (parameterized queries, ORM)
- XSS prevention (output encoding, CSP headers)
- CSRF protection (SameSite cookies, CSRF tokens)
- CORS policy locked down (not wildcard
*) - HTTP security headers (HSTS, X-Frame-Options, X-Content-Type-Options)
Data Security
- Encryption in transit (TLS 1.2+ everywhere, TLS 1.3 preferred)
- Encryption at rest (AES-256 for DBs, S3 SSE)
- PII data identified, minimized, and encrypted at field level where needed
- Database backups encrypted
- No sensitive data in logs (PII, passwords, tokens, card numbers)
Secrets Management
- No secrets in code or environment variables in plain text
- Secrets manager in use (HashiCorp Vault, AWS Secrets Manager, GCP Secret Manager)
- Secrets rotation automated
- IAM roles for service-to-service auth (not static credentials)
Supply Chain & Dependencies
- Dependency scanning (Snyk, Dependabot, npm audit)
- Container image scanning (Trivy, ECR scanning)
- Pin dependency versions in production
- SBOM (Software Bill of Materials) generated for compliance
Incident Response
- Audit logs for all admin actions and data access
- Alerting on anomalous access patterns
- Incident response runbook documented
- Data breach notification process defined (GDPR 72-hour rule)
- Regular penetration testing scheduled
Compliance (as applicable)
- GDPR: data residency, right to deletion, consent tracking
- PCI-DSS: if handling card data — never store raw PANs
- HIPAA: if health data — encryption, audit logs, BAA with vendors
- SOC 2 Type II: access control, availability, confidentiality evidence
Limitations
- This is a reference document and may not cover all edge cases. Always verify architectures before production.
