Reports on Computer Systems Technology :
The Information Technology Laboratory (ITL) at the National Institute of Standards and Technology
promotes the U.S. economy and public welfare by providing technical leadership for the nation’s
measurement and standards infrastructure. ITL develops tests, test methods, reference data, proof-ofconcept implementations, and technical analyses to advance the development and productive use of
information technology. ITL’s responsibilities include the development of technical, physical,
administrative, and management standards and guidelines for the cost-effective security and privacy of
sensitive unclassified information in federal computer systems. The Special Publication 800-series
reports on ITL’s research, guidance, and outreach efforts in computer security, and its collaborative
activities with industry, government, and academic organizations.

INTRODUCTION :
Every organization has a mission. In this digital era, as organizations use automated information
technology (IT) systems to process their information for better support of their missions, risk
management plays a critical role in protecting an organization’s information assets, and therefore
its mission, from IT-related risk.
An effective risk management process is an important component of a successful IT security
program. The principal goal of an organization’s risk management process should be to protect
the organization and its ability to perform their mission, not just its IT assets. Therefore, the risk
management process should not be treated primarily as a technical function carried out by the IT
experts who operate and manage the IT system, but as an essential management function of the
organization.
