What is shift left approach
The Shift Left security strategy means integrating security earlier in the software development lifecycle (SDLC) — as early as design, development, and testing stages, rather than waiting until deployment or production.
Why is it required
- Catch vulnerabilities early
- Reduce cost and effort of fixing issues
- Build secure code by default
- Promote developer ownership of security
How to
1. Secure Code Practices
- Train developers on secure coding (and OWASP Top 10).
- Use linting and static code analysis (SAST) tools in the IDE.
2. Security in CI/CD Pipelines
- Integrate security scanning tools:
- SAST – Static Application Security Testing (e.g., SonarQube, Checkmarx)
- DAST – Dynamic App Security Testing (e.g., OWASP ZAP, Burp Suite)
- SCA – Software Composition Analysis (e.g., Snyk, WhiteSource)
3.Secrets Management
- Use tools like GitHub Secrets, AWS Secrets Manager, or Vault to avoid hardcoding secrets.
4. Infrastructure as Code (IaC) Security
- Analyse Terraform, CloudFormation, or Kubernetes manifests early in the pipeline.
5. Policy as Code
- Use Open Policy Agent (OPA) or HashiCorp Sentinel to enforce security policies programmatically.
