Day 146: DevOps Security — Hardening the Pipeline That Ships Your Code

Yesterday (Day 145) you built a disaster recovery layer that can survive data loss. Today we close the attack surface around everything that pipeline touches. Here’s the agenda:

• Security scanning baked into the CI/CD pipeline (SAST, dependency audit, container scanning)

• Secret management — Vault-backed dynamic credentials, zero plaintext secrets in code or env files

• Compliance-as-code — automated policy checks that gate deployments

• Vulnerability management — CVE tracking dashboard with severity routing

• Security monitoring — real-time alerting on anomalous events

By end of day you’ll have a full SecurityOps dashboard — think Snyk meets Vault meets a SIEM — running locally and verifiable end-to-end.

Security isn’t a post-launch concern. At companies like Netflix and Shopify, security gates run inside the deployment pipeline — a commit that introduces a critical CVE never reaches production, full stop.
