Episode 5 — Master Confidentiality, Integrity, Availability and Accountability
CIA plus accountability forms the backbone of control selection and exam reasoning. We define confidentiality safeguards that restrict unauthorized disclosure, integrity measures that prevent unauthorized alteration, and availability protections that keep services dependable. Accountability ties actions to identities through logging, nonrepudiation, and auditable processes. You’ll learn how these pillars translate into policy statements, technical controls, and validation steps, and how exam items often hinge on identifying the primary objective a control serves when tradeoffs arise.
We deepen the model with concrete scenarios. For a customer database, we compare role-based access and encryption for confidentiality; checksums, digital signatures, and change control for integrity; redundancy, failover, and capacity planning for availability; and identity proofing, logging, and tamper-evident records for accountability. You’ll practice spotting when a proposed fix protects the wrong pillar, such as chasing high availability while leaving integrity unverified. Best practices emphasize layered controls, evidence that proves effectiveness, and prioritizing impacts based on business requirements. We wrap with troubleshooting moves—mapping threats to the correct pillar, aligning metrics with objectives, and documenting assurance so your design stands up under review and on the exam.
