Security As A Phase

Security As A Phase is a software development approach where security practices are treated as a distinct, isolated stage in the development lifecycle, typically occurring after development and before deployment. It involves activities like security testing, vulnerability scanning, and compliance checks concentrated in a dedicated phase, often leading to a 'security gate' that must be passed for release. This contrasts with integrated security approaches, as it can create bottlenecks and delay feedback on security issues until late in the process.

Also known as: Security Phase, Security Gate, Security Stage, Phase-Based Security, Security Checkpoint

🧊Why learn Security As A Phase?

Developers should learn about Security As A Phase to understand traditional security models, especially in legacy or regulated environments like finance or healthcare where compliance mandates periodic audits. It's used when organizations lack mature DevSecOps practices, aiming to catch vulnerabilities before deployment, but it's often criticized for inefficiency compared to continuous security integration. Knowledge of this methodology helps in transitioning to more agile security approaches by highlighting its limitations.
