Actionable DevOps Security Best Practices [Cheat Sheet]

Learning never stops Run incident-response drills and feed lessons back into code, configs, and processes for constant improvement.
Automation beats manual hardeningIaC scanning, container checks, and CI/CD secret scans reduce human error at scale.
Trust nothing by defaultZero-trust architecture, network segmentation, and mutual TLS helps ensure every user, device, and service is verified before accessing resources.

This cheat sheet is designed for:

What’s included?

Secure coding & secrets basics — input validation, hard-coded secret detection, and vault usage guidelines.
