Then it expands on the reasons why it is appropriate to ‘determine external and internal issues’, providing a page of explanation to supplement the succinct and somewhat hard to understand text from ‘27001. “The organisation determines external and internal issues relevant to its purpose and affecting its ability to achieve the intended outcome(s) of the information security management system (ISMS).” Section 4.1 of ‘27003 first states the ‘required activity’ (not the note): NOTE Determining these issues refers to establishing the external and internal context of the organisation considered in Clause 5.3 of ISO 31000:2009.

“The organisation shall determine external and internal issues that are relevant to its purpose and that affect its ability to achieve the intended outcome(s) of its information security management system. Offers practical guidance and supporting information including examples, to help implementers implement.įor example, this is what ‘27001 says in section 4.1, ‘Understanding the organisation and its context’:.In contrast, ISO/IEC 27003 offers pragmatic explanation with plain-speaking advice and guidance for implementers of ‘27001.įor convenience, ‘27003 follows virtually the same structure as ‘27001, expanding clause-by-clause on ‘27001, hence the main sections are: The standard supplements and builds upon other standards, particularly ISO/IEC 27000 and ISO/IEC 27001 plus ISO/IEC 27004, ISO/IEC 27005, ISO 31000 and ISO/IEC 27014.Īs a result of ISO’s intent to make all the Management Systems Standards consistent in structure and form, and in order for it to be usable for ISMS certification purposes, the language of ISO/IEC 27001:2013 is inevitably rather formal, curt and stilted. Its scope is simply to “provide explanation and guidance on ISO/IEC 27001:2013.” ISO/IEC 27003 provides guidance for those implementing the ISO27k standards, covering the management system aspects in particular.
