Knowledge

ISO 27001

Is ISO 27001 right for your organisation? Implementation takes time and effort but isn’t as expensive or as difficult as you might think. Tried and tested toolkits and expert guidance can simplify the process.

Our qualified ISO 27001 lead implementers have trained more than 8,000 professionals worldwide and supported organisations of all shapes and sizes.

This practical expertise means we can offer you real-world advice about the best approach for your budget, timescales and objectives so you can implement or recertify to ISO 27001 as smoothly as possible.

ISO 27001 is the global standard for managing information security, helping organisations protect sensitive data, reduce risks and meet their compliance requirements. It strengthens your security posture, builds trust and creates a resilient ISMS (information security management system).

Certification to the Standard gives your organisation access to new markets and sets you apart from competitors.

ISO 27001 implementation process

1. Familiarise yourself with ISO 27001 and ISO 27002

The ISO/IEC 27001:2022, ISO/IEC 27002:2022 and ISO 27000:2018 standards will serve as your principal points of reference. We have all the resources you need to understand the Standard and its core requirements:

Solutions

2. Assemble a project team and initiate the project

You will first need to appoint a project leader to manage the project . Then you can embark on an information-gathering exercise to review senior-level objectives and set information security goals. Thirdly, you should develop a project plan and project risk register.

Solution

The Lead Implementer course teaches you how to implement an ISMS from beginning to end, including how to overcome common pitfalls and challenges.

3. Conduct a gap analysis

A gap analysis helps you determine which areas of the organisation aren’t compliant with ISO 27001, and what you need to do to become compliant.

Solutions

Quickly and clearly map your current information security measures with this handy tool. It also maps against the controls in Annex A, aligned to ISO/IEC 27002:2022.

A specialist, in-person review of your current information security posture against the requirements of ISO/IEC 27001:2022.

4. Scope the ISMS

Scoping requires you to select which information assets to ring-fence and protect. This requires thought because a scope that’s too big will escalate the time and cost of the project, and a scope that’s too small will leave vulnerabilities untreated.

Solution

Find out how to scope the ISMS effectively by attending the definitive ISO 27001 Lead Implementer course.

5. Initiate high-level policy development and other key ISO 27001 documentation

Set out high-level policies for the ISMS that establish roles and responsibilities and define rules for its continual improvement (clause 10). Additionally, you need to consider how to raise ISMS project awareness through both internal and external communication (clauses 7.3 and 7.4).

Solution

The documentation toolkit will save you weeks of work trying to develop all the required policies and procedures.

6. Undertake a risk assessment

Risk assessments are the core of any ISMS and involve five important aspects: establishing a risk management framework, identifying, analysing and evaluating risks, and selecting risk treatment options.

The risk assessment also helps identify whether your organisation’s controls are necessary and cost-effective.

Solution

This training course will provide a complete path to implementing an effective information security risk assessment.

7. Select and apply controls

Controls should be applied to manage or reduce risks identified in the risk assessment. ISO 27001 requires organisations to compare any controls against its own list of best practices, which are contained in Annex A. Creating documentation is the most time-consuming part of implementing an ISMS.

Solution

The documentation toolkit will save you weeks of work developing and managing control documentation for your ISMS.

8. Develop risk documentation

The risk treatment plan (RTP) and Statement of Applicability (SoA) are key documents required for an ISO 27001 compliance project.

The SoA lists all the controls identified in ISO 27001, details whether each control has been applied and explains why it was included or excluded. The RTP describes the steps to be taken to deal with each risk identified in the risk assessment.

Solution

The documentation toolkit will save you weeks of work developing and managing control documentation for your ISMS.

9. Conduct staff awareness training

Human error has been widely demonstrated as the weakest link in cyber security. Therefore, all employees should receive regular training to increase their awareness of information security issues and the purpose of the ISMS.

Solution

E-learning courses are a cost-effective solution for improving general staff awareness about information security and the ISMS.

10. Assess, review and conduct an internal audit

ISO 27001 requires regular audits and testing to be carried out. This is to ensure that the controls are working as they should be and that the incident response plans are functioning effectively. Additionally, top management should review the performance of the ISMS at least annually.

Solutions

Our auditor courses give you the skills to successfully undertake or lead an ISMS audit project.

11. Opt for a certification audit

If you opt for certification, the certification body you use should be properly accredited by a recognised national accreditation body and a member of the International Accreditation Forum.

Your chosen certification body will review your management system documentation, check that you have implemented appropriate controls and conduct a site audit to test the procedures in practice.

Solution

Our FastTrack experts will help you understand whether certification is necessary and guarantee that you pass the first time with whichever certification body you’ve chosen.
