About this listen
This episode teaches how to analyze system security requirements so you can find contradictions, missing coverage, and ambiguous language before design work locks them in, which is a core ISSEP skill because many exam questions test whether you can recognize that the requirement set itself is the problem. We define requirement quality in practical terms: clarity, measurability, testability, feasibility, and traceability, then show how each property reduces downstream risk. You’ll learn how to spot conflicts like requirements that demand tight access controls while also requiring broad interoperability, gaps like missing logging or missing recovery objectives, and ambiguity like “use strong encryption” without defining algorithms, key management, or acceptance criteria. We also cover best practices for resolving issues through stakeholder clarification, rewriting requirements as verifiable statements, and documenting assumptions so teams can validate them later. Troubleshooting considerations include requirements copied from templates with no context, overlapping requirements that drift apart over time, and exceptions that quietly create security holes.
