IR-1 INCIDENT RESPONSE POLICY AND PROCEDURES

Control: The organization develops, disseminates, and reviews/updates [Assignment: organization-defined frequency]:

a. A formal, documented incident response policy that addresses purpose, scope, roles, responsibilities, management commitment, coordination among organizational entities, and compliance; and

b. Formal, documented procedures to facilitate the implementation of the incident response policy and associated incident response controls.

Supplemental Guidance: This control is intended to produce the policy and procedures that are required for the effective implementation of selected security controls and control enhancements in the incident response family. The policy and procedures are consistent with applicable federal laws, Executive Orders, directives, policies, regulations, standards, and guidance. Existing organizational policies and procedures may make the need for additional specific policies and procedures unnecessary. The incident response policy can be included as part of the general information security policy for the organization. Incident response procedures can be developed for the security program in general and for a particular information system, when required. The organizational risk management strategy is a key factor in the development of the incident response policy. Related control: PM-9.

Control Enhancements: None.

Determine if: (i) the organization develops and formally documents incident response policy; (ii) the organization incident response policy addresses: purpose; scope; roles and responsibilities; management commitment; coordination among organizational entities; and compliance; (iii) the organization disseminates formal documented incident response policy to elements within the organization having associated incident response roles and responsibilities; (iv) the organization develops and formally documents incident response procedures; (v) the organization incident response procedures facilitate implementation of the incident response policy and associated incident response controls; and (vi) the organization disseminates formal documented incident response procedures to elements within the organization having associated incident response roles and responsibilities.

Test: [SELECT FROM: Incident handling capability for the organization].

IR-5 INCIDENT MONITORING

Control: The organization tracks and documents information system security incidents.

Supplemental Guidance: Documenting information system security incidents includes, for example, maintaining records about each incident, the status of the incident, and other pertinent information necessary for forensics, evaluating incident details, trends, and handling. Incident information can be obtained from a variety of sources including, for example, incident reports, incident response teams, audit monitoring, network monitoring, physical access monitoring, and user/administrator reports.

IR-6 INCIDENT REPORTING

Control: The organization:

a. Requires personnel to report suspected security incidents to the organizational incident response capability within [Assignment: organization-defined time-period]; and

b. Reports security incident information to designated authorities.

Supplemental Guidance: The intent of this control is to address both specific incident reporting requirements within an organization and the formal incident reporting requirements for federal agencies and their subordinate organizations. The types of security incidents reported, the content and timeliness of the reports, and the list of designated reporting authorities are consistent with applicable federal laws, Executive Orders, directives, policies, regulations, standards, and guidance. Current federal policy requires that all federal agencies (unless specifically exempted from such requirements) report security incidents to the United States Computer Emergency Readiness Team (US-CERT) within specified time frames designated in the US-CERT Concept of Operations for Federal Cyber Security Incident Handling. Related controls: IR-4, IR-5.

Control Enhancements:
