Episode 1 — Orientation & Outcomes

ISO 27001 certification begins with understanding the broader ISO 27000 family of standards that form the foundation for information security management. ISO 27000 provides vocabulary and principles; ISO 27001 defines the requirements for establishing, implementing, maintaining, and continually improving an Information Security Management System (ISMS); and ISO 27002 supplies detailed guidance for selecting and applying controls listed in Annex A. For exam candidates, recognizing how these documents interact is crucial—ISO 27001 states what must be done, ISO 27002 explains how to do it, and Annex A serves as the reference catalog of 93 controls grouped into themes such as organizational, people, physical, and technological measures. Mastery of this hierarchy helps interpret audit findings, map requirements, and distinguish between mandatory clauses and advisory guidance during both assessment and implementation.

Applying this knowledge in practice means appreciating where each document fits into an organization’s compliance journey. Implementers often start by performing a gap analysis against ISO 27001 clauses, then turn to ISO 27002 for the corresponding control rationale and examples. Annex A becomes the bridge between the management framework and day-to-day technical controls, allowing organizations to tailor safeguards without losing alignment. In exam scenarios, expect questions that test your ability to navigate among these standards, identify control sources, and explain relationships between the normative and informative parts.
