DevSecOps Practices

Overview

A reference on integrating security into the software development lifecycle through DevSecOps practices. Drawn from the DevSecOps Best Practices Guide and DevSecOps Tools Activities Guidebook, these materials emphasize shifting security left — making it a first-class concern from design through deployment rather than an afterthought.

Key Practices

Shift-Left Security

• Threat modeling during design phase (STRIDE framework)
• Security requirements alongside functional requirements
• Static analysis (SAST) integrated into CI pipelines
• Dependency scanning (SCA) for supply chain vulnerabilities

Automated Security Gates

• Dynamic application security testing (DAST) in staging environments
• Container image scanning before deployment
• Infrastructure as Code (IaC) scanning for misconfigurations
• Secret detection in pre-commit hooks and CI pipelines

Security Culture

• Security training as continuous education, not annual compliance
• Blameless post-incident reviews to improve systemic defenses
• Security champions embedded in development teams
• Shared responsibility model across dev, sec, and ops roles

Toolchain Integration

• SAST tools integrated into IDE and CI (SonarQube, Semgrep)
• DAST tools in staging (OWASP ZAP, Burp Suite)
• SCA tools for dependency monitoring (Snyk, Dependabot)
• Secret scanning (TruffleHog, git-secrets)
