A quick way to study this topic
- Hide the explanation and redraw these three anchors from memory.
- Explain the difference between the anchors in your own words.
- Apply the distinction to the worked example below. Check the full lesson for assumptions and exceptions.
- Recall it again tomorrow, then after a few days. A memory hint is a retrieval cue, not a replacement for understanding.

What this chapter explains
- Concepts and mechanisms
- Design, evidence and tradeoffs
- Lifecycle methods and maturity claims
Concepts and mechanisms
Waterfall, iterative, Agile and DevOps approaches organize work differently, but security requirements, architecture, implementation, verification, operation and retirement remain necessary. DevSecOps integrates security responsibilities and feedback into delivery rather than making one final scan the whole process. Maturity models can structure improvement, but a maturity label does not establish every application’s security.
Design, evidence and tradeoffs
Define ownership and acceptance criteria early, use threat modeling and appropriate tests, protect changes and carry operational feedback into development. Cross-functional teams need clear authority, not an assumption that everyone shares every duty. Plan maintenance and retirement as well as release. AI-generated code is implementation that requires normal review, licensing checks and verification; its explanation is not proof of correct behavior.
Lifecycle methods and maturity claims
Waterfall, Agile, DevOps, DevSecOps and scaled frameworks organize work differently; all need security requirements, review, validation and operational feedback. Integrate the product team’s responsibilities rather than making security a final sign-off after design choices are fixed. CMM-style maturity descriptions and OWASP SAMM support different process-improvement discussions; a maturity score does not prove a particular release is secure. Maintain change control through operation, maintenance and retirement as well as initial development.
Worked example
A user story includes tenant authorization acceptance tests before code is written and carries the requirement through deployment verification.
Check your understanding
Why is a final pre-release scanner insufficient as the whole secure lifecycle?
Show explanation
It cannot replace early requirements, architecture decisions, manual context, operating controls and ongoing correction.
