Incident Response Planning#

From power failures to flooding to malicous cyber attacks, incidents occur. While the type of incident and sophistication of the threat actors plays a major role in the outcomes, often the difference between minor and severe consequences have more to do with how you prepare for and respond to the incident.

To get back up and running quickly after an incident, you have to plan well. This means developing written plans – often called incident response plans, disaster recovery plans, or business continuity plans. It also means testing those plans through exercises.

Goals#

  1. Develop and maintain an incident response plan (Level 1 maturity)

  2. Exercise your plans (Level 1 maturity)

  3. Conduct after-action reports following and incident (Level 2 maturity)

Actions#

For Incident Response Planning, the necessary actions vary by maturity as detailed below.

Level 1 Maturity#

    • Include relevant stakeholders from the various business units that may be impacted.

    • Identify and prioritize critical systems.

    • There are many resources available to help you out, including:

  2. Exercise your plan regularly. At least once a year; before each election is better.

  3. When an incident does occur, execute your plan.

  4. Regularly review the your plan to ensure contacts are up to date and procedures are still effective and relevant

Organizations operating at a Level 2 or Level 3 maturity should take additional actions, including:

  1. When an incident does occur, conduct an after action reviews to identify what went right, what went wrong, and make improvements to your plan.
