Inhaltsangabe
NIST Special Publication 800-39, Managing Information Security Risk, is the flagship document in the series of information security standards & guidelines. It provides guidance for an integrated, organization-wide program for managing information security risk resulting from the operation & use of federal information systems. It provides a structured, yet flexible approach for managing risk that is intentionally broad-based, with the specific details of assessing, responding to, & monitoring risk on an ongoing basis provided by other supporting NIST publications. This guidance is not intended to replace or subsume other risk-related approaches that organizations have implemented or intend to implement addressing areas of risk management covered by other requirements. Rather, the risk management guidance described herein is complementary to & should be used as part of a more comprehensive Enterprise Risk Management (ERM) program.NIST Special Publication 800-30 (rev 1), Guide for Conducting Risk Assessments, provides guidance for conducting risk assessments of federal information systems & 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 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, conducting, communicating the results of, & maintaining the assessment) & how risk assessments & other risk management processes complement & inform each other. It also provides guidance on identifying specific risk factors to monitor on an ongoing basis, so that organizations can determine whether risks have increased to unacceptable levels & different courses of action should be taken.NIST Special Publication 800-37 (rev 2), Guide for Applying the Risk Management Framework to Federal Information Systems, provides guidelines for applying the Risk Management Framework to federal information systems to include conducting the activities of security categorization, security control selection & implementation, security control assessment, information system authorization, & security control monitoring. NIST Special Publication 800-137, Information Security Continuous Monitoring (ISCM) for Federal Information Systems and Organizations, assists organizations in the development of an Information Systems Continuous Monitoring (ISCM) strategy & the implementation of an ISCM program that provides awareness of threats & vulnerabilities, visibility into organizational assets, & the effectiveness of deployed security controls. The ISCM strategy & program support ongoing assurance that planned & implemented security controls are aligned with organizational risk tolerance, as well as the ability to provide the information needed to respond to risk in a timely manner.
