NIST SP 800-30
Guide for Conducting Risk Assessments
|Publication Date:||1 September 2012|
PURPOSE AND APPLICABILITY
The purpose of Special Publication 800-30 is to provide guidance for conducting risk assessments of federal information systems and organizations, amplifying the guidance in Special Publication 800-39. Risk assessments, carried out at all three tiers in the risk management hierarchy, are part of an overall risk management process-providing senior leaders/executives with the information needed to determine appropriate courses of action in response to identified risks. In particular, this document provides guidance for carrying out each of the steps in the risk assessment process (i.e., preparing for the assessment, conducting the assessment, communicating the results of the assessment, and maintaining the assessment) and how risk assessments and other organizational risk management processes complement and inform each other. Special Publication 800-30 also provides guidance to organizations on identifying specific risk factors to monitor on an ongoing basis, so that organizations can determine whether risks have increased to unacceptable levels (i.e., exceeding organizational risk tolerance) and different courses of action should be taken.
This publication satisfies the requirements of FISMA and meets or exceeds the information security requirements established for executive agencies9 by the Office of Management and Budget (OMB) in Circular A-130, Appendix III, Security of Federal Automated Information Resources. The guidelines in this publication are applicable to all federal information systems other than those systems designated as national security systems as defined in 44 U.S.C., Section 3542. The guidelines have been broadly developed from a technical perspective to complement similar guidelines for national security systems and may be used for such systems with the approval of appropriate federal officials exercising policy authority over such systems. State, local, and tribal governments, as well as private sector organizations are encouraged to consider using these guidelines, as appropriate.
9 An executive agency is: (i) an executive department specified in 5 U.S.C., Section 101; (ii) a military department specified in 5 U.S.C., Section 102; (iii) an independent establishment as defined in 5 U.S.C., Section 104(1); and (iv) a wholly owned government corporation fully subject to the provisions of 31 U.S.C., Chapter 91. In this publication, the term executive agency is synonymous with the term federal agency.
