Actionable DevOps Security Best Practices [Cheat Sheet]
After reading this cheat sheet, you'll be able to:
Bake security into every DevOps phase—from coding and IaC to runtime monitoring.
Protect secrets, infrastructure, and pipelines with vaulting, immutable builds, and zero-trust controls.
Detect, respond, and continuously improve using real-time monitoring, drills, and post-incident feedback loops.
Key Takeaways
- Security is a shared DevOps responsibility Developers, ops, and security teams must collaborate on tooling and policy.
- Automation beats manual hardening IaC scanning, container checks, and CI/CD secret scans reduce human error at scale.
- Learning never stops Run incident-response drills and feed lessons back into code, configs, and processes for constant improvement.
