Episode 21 — Build and release software using secure development practices

The exam expects you to treat software security as a life cycle with evidence at every phase, not as a post-build scan. This episode lays out how secure development integrates requirements, design, implementation, verification, and release. You will connect secure coding standards to concrete artifacts like language-specific guidelines, dependency policies, and static analysis gates that block known anti-patterns before code merges. Threat modeling belongs early and yields a short list of abuse cases and data-flow diagrams that map trust boundaries around payment data, authentication, and administrative functions. Dependency hygiene and software composition analysis are emphasized because third-party libraries often introduce the riskiest defects; you should recognize answers that require version inventories, vulnerability impact reviews, and fast patch propagation. Testing must be layered: unit tests that check input validation and error handling, static and dynamic application security testing for common classes of flaws, and targeted manual checks for logic issues automation misses.We then move from development to controlled release. Build pipelines must be deterministic and repeatable, with signed artifacts, isolated runners, and promotion only from approved repositories, because provenance is part of assurance. Environments are segregated so production secrets never touch development, and change records show who approved deployments and why. When payment data is involved, secure key handling, configuration management, and least privilege for service accounts are non-negotiable. Troubleshooting guidance addresses flaky gates that teams bypass, scanning deaf spots in non-web services, and the false sense of safety from a single “clean” tool report. The exam favors answers that combine prevention and verification: standards plus training for developers, automated gates plus human review where risk warrants, and release checklists that include rollback, monitoring readiness, and emergency fixes that still flow through post-deployment validation. Pick the options that leave an evidence trail tying code to a threat model, tests, approvals, and a signed, controlled release.
