ISO/IEC 27032 Cybersecurity Guidelines

Current edition: ISO/IEC 27032:2023 · guidelines

Guidelines for strengthening cybersecurity in the internet environment: the risks that arise from connectivity, the threats and attack methods involved, and the controls and cooperation that address them.

What the guidance covers

Cybersecurity in the internet environment

ISO/IEC 27032 helps organisations understand internet-related security risk and select controls, building on ISO/IEC 27001 and ISO/IEC 27002.

Stakeholder roles

Responsibilities of individuals, organisations and providers in the internet environment.

Threats and attack methods

Common attack vectors and how they exploit internet exposure.

Risk assessment

Internet-facing risks assessed within your security risk process.

Controls

Organisational, people and technical controls for internet-facing risk.

Incident management

Detection, response and coordination for cyber incidents.

Information sharing

Cooperation and coordination with partners and authorities.

Awareness

Staff awareness of phishing, social engineering and safe practice.

Supplier exposure

Internet-facing risk from suppliers and connected services.

Why organisations implement it

What a cybersecurity programme delivers

Reduced exposure

Internet-facing risks identified and treated in priority order.

Faster response

Incident handling and coordination practised before they are needed.

Board visibility

Cyber risk reported in business terms.

Customer confidence

A structured answer to cyber questions from customers and insurers.

Regulatory support

A practical basis for NIS2-style cyber risk expectations.

Builds on your ISMS

No parallel system: the guidance feeds your ISO/IEC 27001 controls.

How we work

Path to a stronger cyber posture

One AEC methodology from first assessment to a sustained programme, delivered by registered lead auditors.

  1. AssessInternet exposure, threats and current controls reviewed
  2. DesignControl improvements and responsibilities agreed
  3. ImplementControls and processes put in place
  4. TrainAwareness and incident response training
  5. VerifyTesting, exercises and internal audit
  6. SustainControls maintained within your ISMS
No ISMS yet

Cyber baseline

We assess exposure and set a prioritised improvement plan, often as a first step to ISO/IEC 27001.

Typically 1 to 2 months

ISMS enhancement

We use the guidance to strengthen internet-facing controls in your ISMS.

Typically 2 to 4 months
Customer or insurer request

Readiness review

We test controls against the questions you are being asked.

Typically 1 month
How it is recognised

Guidelines, implemented through your ISMS

ISO/IEC 27032 is a set of guidelines and is not certifiable on its own. Organisations apply it within an ISO/IEC 27001 information security management system, which can be certified by an accredited certification body. AEC helps you apply the guidance and prepares your ISMS for audit.

Practical

Guidance turned into controls you can operate and evidence.

Certifiable route

Where certification is needed, the route is ISO/IEC 27001.

No guarantees

We prepare you thoroughly and never promise an outcome only an independent auditor can decide.

Questions

ISO/IEC 27032 FAQ

Can we be certified to ISO/IEC 27032?

No. ISO/IEC 27032 is a set of guidelines. Where certification is needed, organisations apply it through an ISO/IEC 27001 ISMS, which accredited certification bodies certify.

How is it different from ISO/IEC 27001?

ISO/IEC 27001 sets requirements for an information security management system. ISO/IEC 27032 gives focused guidance on internet-related cyber risk that you can apply within that system.

Is it useful if we do not plan ISO/IEC 27001?

Yes. It provides a structured way to assess and improve internet-facing security, and the work carries over if you pursue ISO/IEC 27001 later.

Does AEC test our systems?

Our work covers risk assessment, controls, processes and readiness. Where technical testing such as penetration testing is needed, we help you scope it and use the results in your risk treatment.

Certification, where sought, is carried out by independent, accredited certification bodies. AEC prepares organisations and does not guarantee audit outcomes.
