FYI - ISO 17799 is about security and best practices.  I don't have an answer, but wanted to clarify the question a bit for the sake of others.

But What Is ISO 17799?
ISO17799 is actually "a comprehensive set of controls comprising best practices in information security". It is essentially, in part (extended), an internationally recognized generic information security standard.

Its predecessor, titled BS7799-1, has existed in various forms for a number of years, although the standard only really gained widespread recognition following publication by ISO (the International Standards Organization) in December of 2000. Formal certification and accreditation were also introduced around the same time.
