ISO/IEC 27400 Foundation (PECB) — Lesson 4: Risk Review, Evidence, Incident Awareness, Responsibilities, and Improvement

Learning Objectives

• Interpret the requirements, principles, roles, and dependencies shaping risk review, evidence, incident awareness, responsibilities, and improvement.
• Apply a practical workflow and create a reviewable IoT improvement action register.
• Evaluate the exception where privacy responsibilities are unclear after device resale and determine proportionate follow-up.

Detailed Topics

• Risk Review applied to the course scenario and expected evidence.
• Evidence applied to the course scenario and expected evidence.
• Incident Awareness applied to the course scenario and expected evidence.
• Responsibilities applied to the course scenario and expected evidence.
• and Improvement applied to the course scenario and expected evidence.

Instructor Demonstration

The instructor traces a case involving a connected-products team reviewing devices, applications, cloud services, communications, data, and suppliers. The demonstration links decisions to objective evidence, records the result in IoT improvement action register, and tests the condition where privacy responsibilities are unclear after device resale.

Hands-On Exercise

Complete a controlled exercise covering Risk Review, Evidence, Incident Awareness, Responsibilities, and Improvement. Confirm scope and responsibilities, examine the stated exception, reach a supported conclusion, and preserve the outcome in IoT improvement action register.

1. Define the objective, boundaries, stakeholders, criteria, and expected work product.
2. Perform the activity while recording assumptions, observations, evidence, and decisions.
3. Test normal operation, the exception, and an escalation or follow-up condition.
4. Document conclusions, owners, deadlines, verification methods, and review triggers.

Scenario Analysis

• Identify the requirement or control with the strongest influence on the scenario outcome.
• Compare two defensible responses and explain their risk, operational, and evidence trade-offs.
• Decide how the IoT improvement action register should be approved, retained, reviewed, and updated.

Troubleshooting Guidance

Start where expected practice and observed evidence first diverge. Separate a missing record from an ineffective process, distinguish unclear ownership from a control failure, and treat “privacy responsibilities are unclear after device resale” as a hypothesis until tested against the applicable criteria and intended outcome.

Validation Checklist

• Scope, roles, criteria, stakeholders, dependencies, and intended outcomes are explicit.
• The IoT improvement action register connects conclusions to objective, reviewable support.
• Normal operation, the stated exception, escalation, and follow-up were evaluated.
• Owners, due dates, verification methods, review triggers, and improvement actions are clear.

Lesson Outcome

Learners can apply Risk Review, Evidence, Incident Awareness, Responsibilities, and Improvement, explain the reasoning used, and defend the result through IoT improvement action register.
