DevSecOps: Security From the Start in Software Development
Nico FreitagIT-Sicherheit
Security must not be an afterthought. DevSecOps integrates security into every phase of the development process – from planning to deployment. The classic approach of 'develop first, test security later' no longer works. Security vulnerabilities found late cost 10-100x more than those caught early.
What Is DevSecOps?
DevSecOps extends DevOps with security as an integral component:
Shift Left – Security is brought in as early as possible.
Automation – Security tests are automated in the CI/CD pipeline.
Shared Responsibility – Security is everyone's job, not just the security team's.
More on secure development in our Secure Coding Guide.
Security in the CI/CD Pipeline
Automated security tests in every phase:
Pre-Commit: Secret scanning, security linting
Build: SAST, SCA for dependency checks
Test: DAST, container image scanning
Deploy: IaC security scanning, runtime protection
More on CI/CD in our CI/CD Pipeline Guide.
Security Tools for Developers
Key DevSecOps tools:
SAST: SonarQube, Semgrep, CodeQL
SCA: Snyk, Dependabot, OWASP Dependency-Check
Secret Scanning: GitLeaks, TruffleHog
Container Security: Trivy, Anchore
IaC Scanning: Checkov, tfsec, KICS
The OWASP Top 10 forms the foundation for all security testing.
Building a DevSecOps Culture
Tools alone aren't enough – culture change is needed:
Security Champions – One security contact per dev team.
Training – Regular security training for developers.
Bug Bounty – Rewards for found vulnerabilities. More in our Bug Bounty vs. Pentest article.
Blameless Post-Mortems – Learn from mistakes without blame.
At AXIS/PORT., we help development teams implement DevSecOps correctly from the start.
Conclusion
DevSecOps is the modern way to develop secure software. Automation and culture change are key. At AXIS/PORT., we support teams on this path.
