Introduction

You want to lean how to define ISO 27001 Scope? You are unsure about how to go about it, where to start, what to include and how to write it?

In this article I am going to show you how to quickly and simply write, define and implement ISO 27001 Scope.

I am Stuart Barker the ISO 27001 Ninja and this is how to define ISO 27001 Scope.

Which ISO 27001 Clause Applies to Scope?

ISO 27001 scope is a requirement of ISO 27001 Clause 4.3 Determining The Scope Of The Information Security Management System. This video tutorial shows you what the requirement of the standard is and how to implement it to pass the audit.

What is ISO 27001 Scope

ISO 27001 scope is the scope of the ISO 27001 The Information Security Management System (ISMS)

We are going to build an information security management system with the information security policies and apply it to ‘something’ to get our ISO 27001 certification.

The ‘something’ that we are going to apply it to is the scope.

We document the scope in the ISO 27001 Scope Document Template.

What is an ISO 27001 Scope Statement

The ISO 27001 Scope statement is the statement that will appear on your ISO 27001 certificate. We explore this more in the ISO 27001 Scope Statement Beginner’s Guide.

The ISO 27001 certificate is the public document that you share with customers and potential customers. 

They will use this information to assess if the ISO 27001 certificate covers what they are buying from you and therefore if they can place reliance on it for their needs.

The scope statement shows which parts of your business are certified and it shows them that you are doing the right thing for information security.

If the ISO 27001 scope statement does not cover the products or services that they are buying from you then they cannot place reliance on it and it will not be valid for them.

Consider an extreme example where your ISO 27001 scope statement covers the company stationary cupboard (I know, I know, it is an example) and the customer is buying an online SAAS Platform from you. Does the fact that you have ISO 27001 certification for your stationary cupboard give them assurances that the online SAAS Platform is secure and managed to the standard of ISO 27001?

If you are struggling with this one, let me help you, the answer is no.

What is the scope of ISO 27001?

The actual scope of ISO 27001 as a standard covers information security. It defines information security as the confidentiality, integrity and availability of data. The right people, with the right access, to the right data at the right time. As a standard ISO 27001 is actually a little tricker than that and bats above it’s pay grade in a number of areas. 

Specifically it likes to include catch all statements like complying with all relevant laws. A great catch all and as such it opens up the audit to review all laws that are relevant and seek assurance you are meeting them. In practical terms, most certification auditors are only really comfortable with data protection laws such as those related to GDPR. They will go out of their way to make sure you fully meet the GDPR thus, in effective, expanding the scope of what is in reality a very simple standard.
