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.

Close the gaps with AMS9000 and protect the value of your information

AMS9000 assists you in establishing and maintaining your ISMS

As part of the JKT9000 family of management software modules, AMS9000 is the audit management software. This programme is designed to handle all aspects of an internal audit programme, from planning audits to the follow-up of corrective actions against deficiencies found.

AMS9000 can be used to verify compliance with any kind of standards including ISO 17799 or ISO 27001. Further you can use it to audit e.g. your quality management system (ISO 9000) or your environmental management system (ISO 14000).
The Workflow of the AMS9000-Navigator, ISMS Audit Software

AMS9000 uses a Navigator which includes a brief workflow of the steps being subject to audit management. To enter any of these steps the users just clicks the icon.

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
