This report is intended to inform National Critical Function stakeholders about developing actionable contingency plans. It describes contingency planning for a significant cyber incident, focusing on the importance of planning, the process of developing a plan, and options for operationalizing a plan. It summarizes the major concepts that are explored in detail in a separate how-to guide.
- Why is planning for significant cyber incidents important?
- Why develop a contingency plan?
- How is a contingency plan developed?
- How is a contingency plan used?
Cyber incidents are occurring with increasing frequency, and these incidents are becoming more disruptive and costlier. Some such incidents exceed stakeholders' capacity to respond using everyday means.
The stakes are particularly high with respect to U.S. National Critical Functions (NCFs). Securing NCFs requires unity of effort within the federal government and effective collaboration and cooperation within state, local, tribal, and territorial (SLTT) governments and the private sector.
The Cybersecurity and Infrastructure Security Agency asked the Homeland Security Operational Analysis Center (HSOAC) to develop a contingency planning implementation (how-to) guide, including a contingency plan (CONPLAN) template, that NCF stakeholders could use to develop NCF-specific CONPLANs to guide their response to and efforts to mitigate the impacts of a significant cyber incident affecting their NCFs.
Summarizing key elements of the companion how-to guide, this report is intended to inform leadership and managers in NCF stakeholder organizations across government and the private sector on the purpose, components, and processes for developing an actionable CONPLAN. This report provides an overview of contingency planning for a significant cyber incident, focusing on the importance of planning, the process of developing a plan, and options for operationalizing a plan. It summarizes the major concepts that are explored in detail in the separate how-to guide.
- The challenges in the decisionmaking environment in which response to a significant cyber incident affecting a National Critical Function (NCF) takes place can involve rapidly unfolding incidents, a high degree of uncertainty, an indefinite beginning and end, and an unknown cause.
- Planning can also be critical because government and private-sector responders responsible for NCFs have experienced relatively few significant cyber incidents.
- Contingency plans (CONPLANs) are useful tools to facilitate coordinated, rapid, and effective response to significant cyber incidents and other contingencies.
- Plans help clarify incident response stakeholders' roles and responsibilities, establish requirements for information-sharing, specify coordination mechanisms, identify possible interdependencies and cascading effects, and identify actions to improve preparedness and resilience in advance of a significant cyber incident.
- The process of developing the plan is just as important as the resulting document. The planning process can illuminate authorities, capabilities, and competencies that are relevant to incident response and deepen stakeholders' understanding of their respective roles and responsibilities.
- Building the core planning team is critical to the planning process. The team should include a lead entity and representatives of key organizations responsible for NCF cyber incident response.
- The planning process has five steps: Gather data and survey the threats, develop mission statements and objectives, develop courses of action, draft a plan, and evaluate risks to the plan.
- Stakeholders can operationalize an approved CONPLAN by disseminating it; testing, exercising, and training with it; documenting and reviewing lessons learned; developing a knowledge base on cybersecurity and resilience; and maintaining and updating the plan.
