IR-04 [H] Incident Handling

Control

  1. Implement an incident handling capability for incidents that is consistent with the incident response plan and includes preparation, detection and analysis, containment, eradication, and recovery;
  2. Coordinate incident handling activities with contingency planning activities;
  3. Incorporate lessons learned from ongoing incident handling activities into incident response procedures, training, and testing, and implement the resulting changes accordingly; and
  4. Ensure the rigor, intensity, scope, and results of incident handling activities are comparable and predictable across the organization.

Discussion

Organizations recognize that incident response capabilities are dependent on the capabilities of organizational systems and the mission and business processes being supported by those systems. Organizations consider incident response as part of the definition, design, and development of mission and business processes and systems. Incident-related information can be obtained from a variety of sources, including audit monitoring, physical access monitoring, and network monitoring; user or administrator reports; and reported supply chain events. An effective incident handling capability includes coordination among many organizational entities (e.g., mission or business owners, system owners, authorizing officials, human resources offices, physical security offices, personnel security offices, legal departments, risk executive [function], operations personnel, procurement offices). Suspected security incidents include the receipt of suspicious email communications that can contain malicious code. Suspected supply chain incidents include the insertion of counterfeit hardware or malicious code into organizational systems or system components. For federal agencies, an incident that involves personally identifiable information is considered a breach. A breach results in unauthorized disclosure, the loss of control, unauthorized acquisition, compromise, or a similar occurrence where a person other than an authorized user accesses or potentially accesses personally identifiable information or an authorized user accesses or potentially accesses such information for other than authorized purposes.

Assessment Objective

    1. an incident handling capability for incidents is implemented that is consistent with the incident response plan;
    2. the incident handling capability for incidents includes preparation;
    3. the incident handling capability for incidents includes detection and analysis;
    4. the incident handling capability for incidents includes containment;
    5. the incident handling capability for incidents includes eradication;
    6. the incident handling capability for incidents includes recovery;
  2. incident handling activities are coordinated with contingency planning activities;
    1. lessons learned from ongoing incident handling activities are incorporated into incident response procedures, training, and testing;
    2. the changes resulting from the incorporated lessons learned are implemented accordingly;
    1. the rigor of incident handling activities is comparable and predictable across the organization;
    2. the intensity of incident handling activities is comparable and predictable across the organization;
    3. the scope of incident handling activities is comparable and predictable across the organization;
    4. the results of incident handling activities are comparable and predictable across the organization.

IR-04(01) [H] Automated Incident Handling Processes

Control

Support the incident handling process using [Assignement: automated mechanisms].

Discussion

Automated mechanisms that support incident handling processes include online incident management systems and tools that support the collection of live response data, full network packet capture, and forensic analysis.

Assessment Objective

the incident handling process is supported using [Assignement: automated mechanisms].

IR-04(04) [H] Information Correlation

Control

Correlate incident information and individual incident responses to achieve an organization-wide perspective on incident awareness and response.

Discussion

Sometimes, a threat event, such as a hostile cyber-attack, can only be observed by bringing together information from different sources, including various reports and reporting procedures established by organizations.

Assessment Objective

incident information and individual incident responses are correlated to achieve an organization-wide perspective on incident awareness and response.

IR-04(11) [H] Integrated Incident Response Team

Control

Establish and maintain an integrated incident response team that can be deployed to any location identified by the organization in [Assignement: time period].

Discussion

An integrated incident response team is a team of experts that assesses, documents, and responds to incidents so that organizational systems and networks can recover quickly and implement the necessary controls to avoid future incidents. Incident response team personnel include forensic and malicious code analysts, tool developers, systems security and privacy engineers, and real-time operations personnel. The incident handling capability includes performing rapid forensic preservation of evidence and analysis of and response to intrusions. For some organizations, the incident response team can be a cross-organizational entity. An integrated incident response team facilitates information sharing and allows organizational personnel (e.g., developers, implementers, and operators) to leverage team knowledge of the threat and implement defensive measures that enable organizations to deter intrusions more effectively. Moreover, integrated teams promote the rapid detection of intrusions, the development of appropriate mitigations, and the deployment of effective defensive measures. For example, when an intrusion is detected, the integrated team can rapidly develop an appropriate response for operators to implement, correlate the new incident with information on past intrusions, and augment ongoing cyber intelligence development. Integrated incident response teams are better able to identify adversary tactics, techniques, and procedures that are linked to the operations tempo or specific mission and business functions and to define responsive actions in a way that does not disrupt those mission and business functions. Incident response teams can be distributed within organizations to make the capability resilient.

Assessment Objective

  1. an integrated incident response team is established and maintained;
  2. the integrated incident response team can be deployed to any location identified by the organization in [Assignement: time period].
