Information is the currency of the information age and in many cases is
the most valuable asset possessed by an organization. Information
security management is the discipline that focuses on protecting and
securing these assets against the threats of natural disasters, fraud
and other criminal activity, user error and system failure.
Effective information security can be defined as the 'preservation of
confidentiality, integrity and availability of information.' This book
describes the approach taken by many organizations to realize these
objectives. It discusses how information security cannot be achieved
through technological means alone, but should include factors such as
the organization's approach to risk and pragmatic day-to-day business
operations.
This Management Guide provides an overview of the implementation of an
Information Security Management System that conforms to the requirements
of ISO/IEC 27001:2005 and which uses controls derived from ISO/IEC
17799:2005.
