| Lesson | How to Apply It | |--------|-----------------| | Never trust “crypto‑only” as a security blanket | Treat wallet integration as just another attack surface. Harden the surrounding web stack with the same rigor you apply to smart contracts. | | Immutable infrastructure & zero‑trust networking | Use AWS PrivateLink or VPC‑Peering with strict security‑group whitelists. Deploy each microservice in its own subnet with no inbound internet access. | | Automated configuration compliance | Enable AWS Config rules for S3 (BlockPublicAccess), IAM (least‑privilege), and ECR (image scanning). | | Continuous Dependency Hygiene | Integrate GitHub Dependabot + Snyk (or OSS Index) into CI. Pin major versions, run npm audit nightly, and block merges on high‑severity findings. | | Secrets Management, Not Environment Variables | Store credentials in AWS Secrets Manager or HashiCorp Vault. Pull secrets at runtime via the SDK, never bake them into AMIs or launch templates. | | Defense‑in‑Depth Logging & Alerting | Deploy AWS GuardDuty + CloudTrail Insights + Falco (runtime security). Set up alerts for S3 bucket ACL changes, anomalous IAM API calls, and outbound data spikes. | | Rapid Patch Process for Critical Dependencies | Create a “hot‑patch” pipeline that can push a single container image update without a full release cycle. | | Bug‑Bounty & Responsible Disclosure | Run a public bug‑bounty program (e.g., HackerOne) with a clear SLA. Act on findings within 48 hours. |

| ✅ | Item | Tool/Method | |----|------|-------------| | ☐ | S3 Buckets: All buckets have BlockPublicAcls & IgnorePublicAcls enabled. No bucket is PublicReadWrite. | AWS Config → s3-bucket-public-read-prohibited | | ☐ | Runtime: All containers run on supported LTS versions (Node 20+, Python 3.12). | Dependabot + CI version matrix | | ☐ | Dependency Scanning: Nightly npm audit + Snyk; block PR merges on high severity. | GitHub Actions | | ☐ | Secrets: No plain‑text credentials in code or Dockerfiles. All secrets fetched from Secrets Manager at runtime. | Terraform aws_secretsmanager_secret | | ☐ | Network Segmentation: Each microservice lives in its own subnet with no inbound internet. | AWS Security Groups + VPC Flow Logs | | ☐ | IAM Least‑Privilege: IAM roles have only the permissions needed for the specific service. | IAM Access Analyzer | | ☐ | Logging & Alerting: GuardDuty enabled, CloudTrail logs to a locked S3 bucket, alerts for S3 ACL changes, IAM policy changes, and outbound data > 10 GB/HR. | AWS CloudWatch Alarms | | ☐ | Incident Response Playbook: Up‑to‑date runbook covering containment, evidence preservation, and communication. | Confluence + PagerDuty | | ☐ | Bug Bounty Program: Active on HackerOne with a defined scope, rewards, and a < 48 hr SLA for triage. | HackerOne portal | | ☐ | Periodic Red‑Team Exercise: At least once per quarter, an internal or external red‑team performs a full‑stack attack simulation. | Third‑party consultancy | | Lesson | How to Apply It |
