Discussion (NIST Supplemental Guidance)

It is important that organizations develop and implement a coordinated approach to incident response. Organizational mission and business functions determine the structure of incident response capabilities. As part of the incident response capabilities, organizations consider the coordination and sharing of information with external organizations, including external service providers and other organizations involved in the supply chain. For incidents involving personally identifiable information (i.e., breaches), include a process to determine whether notice to oversight organizations or affected individuals is appropriate and provide that notice accordingly.

Enhancements NIST SOURCE

IR-8(1) Breaches LOW MODERATE HIGH

Include the following in the Incident Response Plan for breaches involving personally identifiable information:

  1. (a) A process to determine if notice to individuals or other organizations, including oversight organizations, is needed;
  2. (b) An assessment process to determine the extent of the harm, embarrassment, inconvenience, or unfairness to affected individuals and any mechanisms to mitigate such harms; and
  3. (c) Identification of applicable privacy requirements.
Discussion

Organizations may be required by law, regulation, or policy to follow specific procedures relating to breaches, including notice to individuals, affected organizations, and oversight bodies; standards of harm; and mitigation or other specific requirements.

Assessment

NIST SP 800-53A REV 5.2.0

Assessment Objectives

  1. personnel or roles that review and approve the incident response plan is/are identified;
  2. the frequency at which to review and approve the incident response plan is defined;
  3. entities, personnel, or roles with designated responsibility for incident response are defined;
  4. incident response personnel (identified by name and/or by role) to whom copies of the incident response plan are to be distributed is/are defined;
  5. organizational elements to which copies of the incident response plan are to be distributed are defined;
  6. incident response personnel (identified by name and/or by role) to whom changes to the incident response plan is/are communicated are defined;
  7. organizational elements to which changes to the incident response plan are communicated are defined;
  8. an incident response plan is developed that provides the organization with a roadmap for implementing its incident response capability;
  9. an incident response plan is developed that describes the structure and organization of the incident response capability;
  10. an incident response plan is developed that provides a high-level approach for how the incident response capability fits into the overall organization;
  11. an incident response plan is developed that meets the unique requirements of the organization with regard to mission, size, structure, and functions;
  12. an incident response plan is developed that defines reportable incidents;
  13. an incident response plan is developed that provides metrics for measuring the incident response capability within the organization;
  14. an incident response plan is developed that defines the resources and management support needed to effectively maintain and mature an incident response capability;
  15. an incident response plan is developed that addresses the sharing of incident information;
  16. an incident response plan is developed that is reviewed and approved by <IR-08_ODP[01] personnel or roles> <IR-08_ODP[02] frequency>;
  17. an incident response plan is developed that explicitly designates responsibility for incident response to <IR-08_ODP[03] entities, personnel, or roles>.
  18. copies of the incident response plan are distributed to <IR-08_ODP[04] incident response personnel>;
  19. copies of the incident response plan are distributed to <IR-08_ODP[05] organizational elements>;
  20. the incident response plan is updated to address system and organizational changes or problems encountered during plan implementation, execution, or testing;
  21. incident response plan changes are communicated to <IR-08_ODP[06] incident response personnel>;
  22. incident response plan changes are communicated to <IR-08_ODP[07] organizational elements>;
  23. the incident response plan is protected from unauthorized disclosure;
  24. the incident response plan is protected from unauthorized modification.
