Episode 7 — Manage Security Within Common SDLC Methodologies

Secure practices must integrate naturally into the software development lifecycle methodologies that organizations actually use, and the CSSLP exam tests your ability to adapt security activities to those different models. This episode lays out how security expectations map into classic waterfall, iterative, agile, and DevOps approaches, focusing on where requirements, design reviews, threat modeling, testing, and risk decisions fit. You will hear how the same control concept, such as code review or security testing, can appear at different times and with different emphasis depending on the lifecycle model. The discussion clarifies which artifacts are typically produced at each stage and how exam questions may describe project rhythms like sprints, release trains, or formal phase gates. Concrete examples then illustrate how to embed security into these lifecycles without blocking delivery or relying on unrealistic processes. Situations such as adding security user stories into agile backlogs, defining “done” criteria that include security checks, inserting risk sign-offs into waterfall design phases, and wiring DevOps pipelines to run automated security tests are explored from an exam perspective. You will learn how to recognize answer choices that respect the underlying methodology while still meeting security and compliance objectives, and how to avoid options that bolt on controls in ways that are unlikely to sustain in practice. This helps you select responses that feel realistic to a development team while still satisfying CSSLP expectations for traceability, verification, and governance across the lifecycle.
