Many people are confused between ISO 27001 gap analysis and risk assessment. This is understandable as the purpose of both is to identify deficiencies in the information security of the company. But, from the perspective of ISO 27001 and a certification auditor, these two are quite different.
What Are ISO 27001 Audit and Gap Analysis?Gap analysis is nothing but reading each section of ISO 27001 and estimating if that requirement is already implemented in your company. When you do so, you can use a scale similar to this:
- • The requirement is not implemented nor planned
- • The requirement is planned but not implemented
- • The requirement is implemented only partially
- • The requirement is implemented but determination, review, and improvement are not performed
- • The requirement is implemented and even measurement and improvement are performed regularly
What Exactly Is A Risk Assessment?Risk assessment is an essential step in ISMS (Information Security Management System) implementation as it allows you to implement security controls only if there are risks that would justify that particular control. In simple words, the higher the risk, the more you need to invest in controls. However, conversely, if there are no risks that would defend a particular control, implementing it would be a waste of time and money. Before implementing security controls, you must perform a risk assessment as it is a key requirement in ISO 27001. On the other hand, it determines the shape of your information security.
What Is The Difference Between Gap Analysis And Risk Assessment?With Gap analysis, you can know how far you are from ISO 27001 requirements/controls. But, you can’t know which problems can occur or which controls to implement. In case of risk assessment, you can know which events can happen and which controls to implement. However, it doesn’t give you an overview of which controls are already implemented. Companies often perform audit and gap analysis before the start of ISO 27001 implementation, to get a feeling of where they are right now, and to find out which resources they will need to employ to implement ISO 27001 audit and gap analysis in London. But, the usefulness of such an approach is uncertain as only risk assessment will show the real extent of what needs to be implemented and in which form.
