ISO/IEC 27001 Lead Implementer (Information Security Management System)

Highlights of course

This course provides instructions on the implementation of ISMS control requirements and on auditing existing control implementations to help organisations prepare for certification in accordance with ISO/IEC 27001. The contents of this guide include the ISMS control requirements that should be addressed by organisations considering certification.

This course helps you to learn each of the controls in Annex A of ISO/IEC 27001 from two different viewpoints:

•implementation guidance – what needs to be considered to fulfil the control requirements when implementing the controls from ISO/IEC 27001, Annex A. This guidance is aligned with ISO/IEC 27002, which gives advice on the implementation of the controls;

•auditing guidance – what should be checked, and how, when examining the implementation of ISO/IEC 27001 controls to ensure that the implementation covers the essential ISMS control requirements. It is important to emphasise that this guide does not cover the implementation or auditing of the ISMS process requirements (the main body of ISO/IEC 27001).

Who should attend

This course is intended to be attended by those involved in:

•designing, implementing and/or maintaining an ISMS;
•preparing for ISMS audits and assessments;
•carrying out internal ISMS audits and assessments1; and
•carrying out ISMS audits and assessments of other organisations.

This course makes reference to the following standards:
•ISO/IEC 27001 – the requirements specification for an ISMS. This International Standard is used as the basis for accredited certification.
•ISO/IEC 27002 – a reference for selecting controls as part of the implementation of an ISMS, and a guidance document for organisations implementing commonly accepted security controls. This course will be updated following any changes to these standards. Organisations
should therefore ensure that the correct version is being used for compliance checks related to pre-certification, certification and post-certification purposes.
