ISO/IEC JTC1/SC 27/WG 3 meeting in Abu Dhabi


At the end of October I was once again privileged to be able to  join ISO/IEC JTC 1/SC 27/WG 3 during the latest of their bi-annual working sessions held in April and October.

Convened by Miguel Bañón, this working group is of particular interest to atsec since it includes work on the international standards and guidance documents relating to ISO/IEC 15408, ISO/IEC 19790 and other documents closely related to evaluation and testing and the provision of security assurance.

I have written in more detail on these standards in:

ISO's work related to the Common Criteria
ISO's cryptographic module work.




A little history on the relationship between ISO/IEC 15408 and the Common Criteria reveals that in the early 1990's, as the various national criteria, including Europe's ITSEC, The Canadian Criteria (CTCPEC) and the US Federal criteria, were brought together in order to create a single set of harmonized criteria, the intention was to publish the new set of "Common Criteria" as an ISO standard. A decision was made to create a more agile  technical community, the Common Criteria Development Board (CCDB), that could produce the work and present it to ISO. This was not done using the ISO "PAS" process, but aimed to produce and submit  a substantially complete work that would allow expeditious instantiation of the work with the full involvement of the ISO community, which could then support the standard's future maintenance within ISO.

Hence, the CCDB and ISO established a close liaison relationship, the Common Criteria were submitted to ISO by the CCDB and the first edition of  ISO/IEC 15408 was published in December of 1999.  Since then the CCDB have continued to liaise with ISO enabling the content  of ISO/IEC 15408 and the "Common Criteria" to remain synchronized. It's a two way relationship allowing for changes and innovations from WG 3 to be brought into the CCDB standards development.

The CCDB was initially comprised of representatives from those  countries contributing their own national criteria, today the CCDB is still a subset of  the  17 members of the CCRA certificate issuing signatory nations and the CCDB standards development efforts reflect the needs of the government agencies which they represent.

From the perspective of commercial industry it is a closed group, a little disconcerting when you realize that at least in the U.S., the stated policy is to adopt COTS products as a means of making government systems, more timely and cost-effective  and the US government emphasizes the benefits of public-private partnership.

So, this has been the status quo for several years: The CCDB updates the Common Criteria and the CEM standards using input from the CCDB members and from the WG 3 experts.  ISO publishes the aligned CC/CEM content as the ISO/IEC 15408 and ISO/IEC 18045 standards.

ISO brings to the table a breadth and depth of constituents far beyond that of the CCDB. SC 27 (IT Security Techniques) currently brings together 53 participating nations, a further 20 observing nation and is in liaison with many industry groups and standards organizations such as:

The various national bodies and liaison organizations represented in WG 3 work closely within their home fields to garner the participation of, and to  represent the interests of their own constituents.

Over time, the success of the Common Criteria has resulted in interest and use of the CC standards far beyond the national Agencies that are the the constituents of the CCDB. The diagram below attempts to illustrate this:



After a year long joint study period, WG3 and the CCDB recognized this evolution, and noting that ISO has more resources, and more widely represents the diverse stakeholders of the Common Criteria standards,  decided that ISO will take the lead in developing the next revision of the standards.

If you are interested in contributing to the development of ISO/IEC 15408 (The "CC"), ISO/IEC 18045 ("The CEM") or other projects within SC 27 then you can do so either through your national body, or through one of the liaison organizations to SC 27.

P.S. in the U.S. the national body is ANSI who are are represented in SC 27 by INCITS.
