Information Security Management

ISO/IEC 27001:2022

The international benchmark for information security management systems, with 93 Annex A controls in the 2022 edition.

Overview

ISO/IEC 27001:2022 sets requirements for an information security management system (ISMS) that preserves confidentiality, integrity and availability of information through a risk management process. The 2022 revision restructured Annex A into four themes — organizational, people, physical and technological — and introduced 11 new controls such as threat intelligence and secure coding.

ISMS implementation field guide

Build a traceable chain from organizational context to risk ownership, treatment, operating controls and improvement evidence.

  1. 1

    Set context and scope

    Identify internal and external issues, interested-party requirements, interfaces and dependencies; document a boundary that matches real operations.

  2. 2

    Assess information-security risk

    Use approved, repeatable criteria to assess risks to confidentiality, integrity and availability and identify accountable risk owners.

  3. 3

    Select and plan treatment

    Choose treatment options, assign owners and due dates, record approvals and residual risk, and keep applicability records consistent with decisions.

  4. 4

    Operate and measure controls

    Define how controls work in practice, what evidence they produce and how the organization will evaluate their effectiveness.

  5. 5

    Review and improve

    Use audit, measurement, incident and management-review results to correct root causes and verify that changes work.

Evidence checklist

  • Current scope and interface map
  • Risk criteria and risk-owner decisions
  • Treatment plan and control applicability rationale
  • Operating samples rather than policy alone
  • Monitoring, audit and corrective-action records

Common failure modes

  • Treating tool purchase as control implementation
  • Leaving third-party interfaces outside scope without analysis
  • Confusing the CISO with the accountable business risk owner
  • Listing controls as implemented without operating evidence

Key concepts examiners test

Risk owner

Person or entity with the accountability and authority to manage a risk.

Statement of Applicability

Mandatory document listing necessary controls, justification and implementation status.

Risk treatment plan

Plan for implementing selected controls, approved by risk owners.

Control attributes

Tags in ISO/IEC 27002:2022 such as control type and cybersecurity concept used to filter controls.

Planning of changes

Clause 6.3 — changes to the ISMS must be planned (new in 2022).

Preparing for the Lead Auditor exam

  • Use the SoA as your audit map — every 'included' control needs evidence of implementation.
  • Sample risk owners and ask them to explain residual risk they accepted.
  • Grade findings by impact on system effectiveness, not by the number of instances alone.
  • Verify management review inputs include changes in interested-party needs (added in 2022).

Preparing for the Lead Implementer exam

  • Agree risk assessment methodology early — consistency and comparability are explicit requirements.
  • Map existing controls to the 93 Annex A controls before writing new policies.
  • Plan at least one full internal audit cycle and management review before Stage 2.
  • Keep the scope statement precise about interfaces and dependencies with third parties.
