![]()
The
ISO 17799 2000 standard is all-encompassing. It takes a
very broad
approach to information security. In the context of this standard, the term
information includes all
forms of data, documents, communications,
conversations, messages, recordings, and photographs. It includes
everything from digital data and email to
faxes and
telephone
conversations. It includes
all forms of information.
The ISO/IEC 17799 2000 standard, and our
interpretation of it, consists of
recommended information security practices.
These recommended practices
are found in sections 3 to 12. Since these recommendations start in section
3,
the following material also starts in section 3.
