A Secure Software Development Life Cycle (SSDLC) embeds security into every phase of software delivery rather than treating it as a final step. The post outlines five pillars for building an effective SSDLC: Visibility (knowing what systems and dependencies you have), Early Feedback (surfacing security issues in IDEs, PRs, and CI/CD pipelines), Developer Adoption (choosing tools developers will actually use), Consistency (applying uniform security standards across all teams and stacks), and Actionability (prioritizing findings by risk and business impact). IBM research is cited showing that fixing vulnerabilities early costs ~$80 vs ~$7,600 in production. The post also promotes Aikido Security as a platform that integrates SAST, DAST, and SBOM tracking into developer workflows, and offers a downloadable CTO security checklist.
