Episode 4 — Master Confidentiality, Integrity, Availability and Resiliency
Confidentiality, integrity, availability, and resiliency form the core lens through which secure software decisions are evaluated on the CSSLP exam. This episode revisits each term with precise, exam-ready definitions and connects them directly to software behaviors, from how data is stored and transmitted to how services respond during component failures. Confidentiality is framed as controlled disclosure, integrity as trustworthy and unaltered state, availability as timely and reliable access, and resiliency as the capacity to absorb disruption without losing control or important information. Attention is given to how these principles show up in requirements language and architecture descriptions that you are expected to interpret correctly.
Exam scenarios often revolve around tradeoffs among these four principles, and the discussion uses concrete examples to illustrate those tensions. Design choices such as adding strong encryption, introducing additional validation checks, or implementing strict fail-closed behaviors are analyzed in terms of how they support one principle while pressuring another. Sample reasoning patterns demonstrate how to decide which principle should dominate in a given context, such as safety-critical systems, customer-facing portals, or regulatory reporting platforms. Short mental checklists help you read questions and quickly identify which principle is truly at stake, improving your chances of selecting the best answer among several plausible controls.
