DevSecOps: Integrating Security into Your Development Pipeline
DevSecOps (Development, Security, Operations) is the practice of integrating security throughout the software development lifecycle — rather than treating it as a separate gate at the end. The goal is to make security a shared responsibility, embedded in every stage of development and delivery.
Security in Each Stage of the Pipeline
- Code commit: Pre-commit hooks check for secrets, lint for common security anti-patterns
- Build: Static Application Security Testing (SAST) analyses source code for security vulnerabilities. Dependency scanning checks for vulnerable libraries.
- Test: Dynamic Application Security Testing (DAST) runs automated security tests against the running application. Integration tests include security-focused test cases.
- Release: Container image scanning before deployment. Infrastructure-as-Code security scanning (Checkov, tfsec).
- Deploy: Deployment to production includes security controls verification. Runtime security monitoring starts.
- Operate: Continuous monitoring for anomalous behaviour. Intrusion detection. Log analysis.
Tools We Use
- SAST: Semgrep, SonarQube, CodeQL
- Dependency scanning: Snyk, Dependabot
- Secret scanning: GitHub Secret Scanning, Gitleaks
- DAST: OWASP ZAP, Burp Suite
- Container scanning: Trivy, Snyk Container
- IaC scanning: Checkov, tfsec
The Business Case
Fixing a vulnerability in design costs 10x less than fixing it in testing, and 100x less than fixing it in production after a breach. DevSecOps reduces the cost of security by catching issues early.
