ISO27k Toolkit Overview and Contents 3v2
Introduction
This document was created by ISO/IEC 27001 and 27002 implementers belonging to the ISO27k
Implementers' Forum. It lists the items typically required to document an Information Security
Management System (ISMS) suitable for certification against ISO/IEC 27001.
Scope
The checklist simply lists the documents typically produced or used by an ISMS implementation
project, plus those produced by and forming part of a mature ISMS.
The checklist itself is the product of the first phase of a collaborative project to build an ISO27
toolkit – a suite of materials to assist those implementing an ISMS using the ISO/IEC 27000-
series standards.
The second phase of the project is currently in progress, developing worked
examples/samples of the ISMS documents listed on this checklist. Links are provided below to the
sample documents already completed and published. Eventually, we hope to complete the toolkit,
although it may not make much sense to generate generic samples of all the documents listed. If
you own examples of other items on the list, or additional examples of those we already have,
please submit them to expand the toolkit (contact Gary@isect.com).
Purpose
The checklist is meant to help those implementing or planning to implement the ISO/IEC
information security management standards. Like the ISO/IEC standards, it is generic and needs
to be tailored to your specific requirements. The details do vary between organizations.

This is not a definitive list of ISMS-related documents for all organizations and circumstances. It
simply reflects the accumulated experience and knowledge of the contributors of the most common
ISMS-related documents. It is merely guidance. Please refer to the ISO/IEC standards and/or
consult your accredited ISMS certification body for a more definitive, complete and accurate list.

Notes
The above items, if required by your organization, need to be drafted and reviewed by suitable
people, then (for formal documents such as policies at least) approved by management. All
versions must be controlled as per ISO/IEC 27001 section 4.3.2 e.g. by ensuring that all
approved/current items are uploaded to a controlled area of the corporate intranet, with any
superseded versions being removed from that area at the same time. Evidence of the approval
status for the documents (e.g. committee minutes, approval signatures etc.) should be retained by
the Information Security Manager, Compliance Officer or equivalent for audit purposes. All
documents should be reviewed and if necessary updated every year or two, being careful to
update any cross-references.
For reference, ISO/IEC 27001:2005 requires the organization to define and document:
The Scope and Boundary of the ISMS (identified in clause 4.2.1a) and its Objectives
(4.3.1a);
An ISMS Policy being a superset of the information security policy (4.2.1b);
A description of the Risk Assessment Approach (4.2.1c) or Methodology (4.3.1d);
A Risk Assessment or Risk Analysis Report identifying information assets in scope of the
ISMS, threats to those assets, vulnerabilities that might be exploited by the threats and the
impacts that loss of confidentiality, integrity and availability may have, analyzing and evaluating
the risks (4.2.1c,d,e,f,g and 4.3.1e);
The Risk Treatment Plan which identifies evaluated options for the treatment of risks (4.2.1f
and 4.2.2b);
Management Approvals and Authorizations confirming that management approves the
residual risks and authorizes the ISMS (4.2.1h and 4.2.1i);
The Statement of Applicability (4.2.1j) defining the selected control objective and controls
along with the reasons they were selected, identifying control objectives and controls currently
implemented and documenting the reasons for excluding any control objectives and controls
(4.2.1g, drawing on Annex A which summarizes the controls in ISO/IEC 27002);
Documented Procedures to ensure effective planning, operation and control of the security
processes, and describe how to measure the effectiveness of the controls (4.3.1g)
Records demonstrating that the ISMS is actually in operation e.g. management decisions,
outputs of monitoring and review procedures, risk assessments, ISMS audit reports, security
plans, occurrences of significant security incidents, visitors’ books, completed access
authorization forms etc. (4.2.3, 4.3.1 and 4.3.3).
