Introduction
This guideline has been written by members of the ISO27k Implementers' Forum, an international online community of neatly 1,000 practitioners actively using the ISO/IEC 27000-family of Information Security Management System (ISMS) standards known colloquially as "ISO27k", and base at ISO27001security.com. Our primary aim is to contribute to the development of the new standard ISO/IEC 27007 by providing what we, as experienced ISMS implementers and IT/ISMS auditors, believe is worthwhile content. A secondary aim to provide a pragmatic and useful guideline for those involved in auditing ISMSs.
At the time of first writing this guideline (February-March 2008). ISO/IEC 27007 is currently at the first Working Draft stage ("ISO/IEC WD 27007") and has been circulated to ISO member bodies for study and comment by March 14 2008. Its working title is "Information Technology - Security techniques - Guidelines for information security management systems auditing".
The Proposed outline structure of ISO/IEC WD 27007 is presently as follows:
- Foreword and introduction
1. Scope
2. Normative references
3. Terms and definitions
4. Principles of auditing
5. Managing an audit programme
6. Audit activities
7. Competence and evaluation of auditors
- Bibliography
In the proposed structure, section 6 should presumably explain how to go about auditing an ISMS. The current working draft has headings for a guide to audit process but little content on the actual audit tests to be performed, although in section 6.3.1 it identifies a list of items that are required by ISO/IEC 27001 and says that "Auditors should check that all these documents exist and conform to the requirements in ISO/IEC 27001"2005". This is probably the most basic type of ISMS audit test: are the specified ISMS documents present? We feel that a generic ISMS audit checklist (often called an "Internal Controls Questionnaire" by IT auditors) would be a very useful addition to the standard and producing one was a key aim of this guideline - in fact we have produced two (see the appendices). We also aim to contribute content draft 27007 and hope to track its development through future revisions.

ISO/IEC 27005 Information technology -- Security techniques -- Information security risk management
This standard was published in June 2008.
“ISO/IEC 27005:2008 provides guidelines for information security risk management. It supports the general concepts specified in ISO/IEC 27001 and is designed to assist the satisfactory implementation of information security based on a risk management approach. Knowledge of the concepts, models, processes and terminologies described in ISO/IEC 27001 and ISO/IEC 27002 is important for a complete understanding of ISO/IEC 27005:2008. ISO/IEC 27005:2008 is applicable to all types of organizations (e.g. commercial enterprises, government agencies, non-profit organizations) which intend to manage risks that could compromise the organization's information security.”
ISO/IEC 27005 revises the Management of Information and Communications Technology Security (MICTS) standards ISO/IEC TR 13335-3:1998 plus ISO/IEC TR 13335-4:2000.
Some personal comments on ’27005
[These are just my personal perspective. They inevitably reflect my own prejudices and limited experience with information security risk management.]
At around 60 sides, ISO/IEC 27005 is a heavyweight standard although the main part is just 24 pages, the rest being mostly annexes with examples and further information for users. There is quite a lot of meat on the bones, reflecting the complexities in this area.
Although the standard defines risk as “a combination of the consequences that would follow from the occurrence of an unwanted event and the likelihood of the occurrence of the event”, the risk analysis process outlined in the standard indicates the need to identify information assets at risk, the potential threats or threat sources, the potential vulnerabilities and the potential consequences (impacts) if risks materialize. Examples of threats, vulnerabilities and impacts are tabulated in the annexes; although incomplete, these may prove useful for brainstorming risks relating to information assets under evaluation. It is clearly implied that automated system security vulnerability assessment tools are insufficient for risk analysis without taking into account other vulnerabilities plus the threats and impacts.
The standard includes a section and annex on defining the scope and boundaries of information security risk management which should, I guess, be no less than the scope of the ISMS.
The standard deliberately remains agnostic about quantitative and qualitative risk assessment methods, essentially recommending that users choose whatever methods suit them best, and noting that they are both methods of estimating, not defining, risks. Note the plural - 'methods' - the implication being that different methods might be used for, say, a high-level risk assessment followed by more in-depth risk analysis on the high risk areas. The pros and cons of quantitative vs qualitative methods do get a mention.
The steps in the process are (mostly) defined to the level of inputs -> actions -> outputs, with additional “implementation guidance” in similar style to ISO/IEC 27002.
The standard incorporates some iterative elements e.g. if the results of an assessment are unsatisfactory, you loop-back to the inputs and have another run through. For those of us who think in pictures, there are useful figures giving an overview of the whole process and more detail on the risk assessment -> risk treatment -> residual risk bit.

AMS9000 Audit Management Software
The value of information within an organisation is enormous. But there are lots of threats that put this value at risk. How to protect it best? Typically individual solutions are used to respond to specific threats. However, to be successful you need a framework for information security. This is a management system as it is described in ISO 17799 and BS 7799. It allows to integrate individual solutions into one concept.
The PDCA model is already used in other management systems like quality management. And it works fine within the information security management system (ISMS):
* Plan: Establish the information security management system (ISMS).
* Do: Implement and operate the ISMS.
* Check: Monitor and review the ISMS.
* Act: Maintain and improve the ISMS.

The standards ISO 17799/ISO27001 and BS 7799
ISO 17799 (ISO 27001 or BS 7799-1) is a code of practice for information security management. It gives recommendations for information security management, i.e. for initiating, implementing or maintaining security. ISO 17799 provides a comprehensive set of controls comprising best practices in information security. It is intended to provide a common basis for developing organisational security standards and effective security management practice. It provides recommendations and guidance that usually an organisation should address. This means that an organisation is requested to go ahead from this starting point or common basis. This has to be kept in mind when using general checklists to audit an ISMS. The specifics of an organisation always have to shine through the design of the ISMS including the audit checklist and audit procedures.
BS 7799-2 is concerned with the management system. The standard mentions four major areas:
* Information Security Management System (ISMS)
* Management Responsibility
* Management Review
* ISMS Improvement
Benefits for your information security management system
AMS9000 is an audit software tool to audit an information security management system. It supports the entire audit process.
It can be used to audit compliance with standards such as ISO 17799 / ISO 27001 and BS 7799.
Further benefits are:
* AMS9000 kann zum Auditieren nach ISO 17799 / SO 27001, BS 7799 und anderer Standards zur Informationssicherheit benutzt werden. Darüber hinaus kann es für andere Audit benutzt werden, wie sie etwa aus dem Qualitätsmanagement bekannt sind. Sie brauchen nicht für jeweils verschiedene Audits eine andere Auditsoftware.
* AMS9000 can be used to audit against ISO 17799 and BS 7799 or any other information security management standard. However, it can be used for other audits as well known from quality management. You do not need a different audit tool for each kind of audit.
* Get evidence of conformance with ISO 17799 or whatever checklist you apply. This can be helpful when you like to register to BS 7799 part 2.
* Efficient and quick analysis and report significantly reduces time and resources necessary.
* Low training needs through ease to use and intuitive handling of the software.
* Management of corrective actions assists you in improving your information security management.
