The NIST (National Institute of Standards and Technology) has several special publications that provide guidance on information security and risk management.
The term "impact" is used in the context of risk management to describe the potential adverse effects that could result from a security incident. For example, a security incident could result in the loss or theft of sensitive information, the disruption of critical systems or services, or damage to an organization's reputation.
Of the four options provided, the NIST document that defines impact is NIST SP 800-30, "Risk Management Guide for Information Technology Systems." This document provides guidance on how to identify, assess, and manage risks to IT systems and the information they contain.
NIST SP 800-30 defines impact as "the magnitude of harm that can be expected to result from the consequences of unauthorized disclosure, modification, destruction, or disruption of information or information systems." The document goes on to provide guidance on how to assess the impact of different types of security incidents and how to use that information to prioritize risk management activities.
NIST SP 800-53, "Security and Privacy Controls for Information Systems and Organizations," provides a catalog of security and privacy controls that organizations can use to protect their information and information systems. While this document does not specifically define impact, it does include controls related to impact assessment and mitigation.
NIST SP 800-26, "Security Self-Assessment Guide for Information Technology Systems," provides guidance on how to conduct self-assessments of information system security. While this document also does not specifically define impact, it does include guidance on how to assess risks and vulnerabilities and develop mitigation strategies.
NIST SP 800-53A, "Assessing Security and Privacy Controls in Federal Information Systems and Organizations: Building Effective Assessment Plans," provides guidance on how to assess the effectiveness of security and privacy controls in federal information systems. While this document does not specifically define impact, it does include guidance on how to assess the potential impact of security incidents and how to use that information to prioritize assessment activities.
