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.

Fazit

DevSecOps is the modern way to develop secure software. Automation and culture change are key. At Axis/Port., we support teams on this path.
