ISO 27001 CERTIFICATION EXPLAINED

Contrary to common belief, certification is applicable against ISO 27001, rather than ISO 17799. The certification itelf is international, in that National Accreditation Bodies have a mutual recognition model in place enabling certifications granted in one territory to be recognized in another. Clearly, this is essential for an international standard.

Common reasons to seek certification include: Organisational assurance; trading partner assurance; Competitive advantage (market leverage); reduction or elimination of trade barriers; reduced regulation costs; and so on.

To meet the certification requirements, an organization's ISMS must be audited by a 'Certification Body' (or strictly speaking, an assessor who works for a Certification Body). There is a clear segregation of dutues here: the assessor must be independent of consultancy and training.

A Certification Body must have been accredited by the National Accreditation Body for the territory in question (eg: UKAS in the UK). This helps ensure that the Certification Bodies meet national and international standards for their services, and ensure consistency. In respect to ISO 27001, this is typically a document called EA-7/03 (‘Guidelines for Accreditation of Bodies Operating Certification / Registration of Information Security Management Systems’).

The following diagram may clarify this process:



Different certification bodies tend to adopt slightly different approaches to the exercise, with some being more 'hands on' than others. However, the following six step process is a fairly common one:

1 - Questionnaire (the Certification Body obtains details of your requirements)
2 - Application for Assessment (you complete the application form)
3 - Pre-assessment Visit or a ‘Gap Analysis’ (optional).
4 – The Stage 1 Audit (a ‘Document Review’). This is the first part of the audit proper.
5 - The Stage 2 Audit (otherwise called the ‘Compliance Audit’)
6 – Ongoing Audits
