Episode 23 — A.5.1–5.2 — Policies for InfoSec; Roles & responsibilities

A.5.1 requires establishing a set of information security policies that provide direction and support consistent with business objectives and relevant laws and regulations. For the exam, remember the essentials: policies must be approved by management, communicated to the organization, reviewed at planned intervals, and supported by lower-level standards and procedures. A.5.2 complements this by requiring clear definition of information security roles and responsibilities, ensuring ownership for decision-making and accountability for control operation. These controls anchor governance, providing the “why” and “who” that guide every process within the ISMS.

Implementation begins with a master policy that articulates intent, principles, scope, and authority, then cascades into domain policies (e.g., access control, acceptable use, incident response) with mapped responsibilities. Organizations often codify accountability using RACI matrices linked to job descriptions and onboarding checklists. Pitfalls include policy sprawl without harmonization, outdated documents that conflict with practice, and ambiguous responsibilities that delay decisions during incidents. Best practices include policy classification and versioning, attestation workflows, and integration with performance management to reinforce accountability. Candidates should be able to connect these controls to leadership clauses, competence requirements, and internal audit criteria, explaining how policy clarity and role definition reduce variance, accelerate compliance tasks, and improve auditor confidence in governance maturity.
