Performing cyber incident simulations (CIS) is essential to ensure that incident response plans and processes are effective. In general, a CIS conducted as a tabletop exercise or real-case simulation. While tabletop exercises involve walking through a hypothetical scenario and discussing how the organization would respond, simulations include running a mock attack to test the organization’s response capabilities.
It is important to identify any gaps or weaknesses in the incident response plan during testing in order to make necessary adjustments. Testing can also help identify areas where employees need additional training or resources to effectively respond to cyber incidents. For example, it might be helpful to define in more detail the roles and responsibilities of different team members in responding to an incident to ensure that everyone knows what they are responsible for and what actions they need to take. As communication is critical during a cyber incident, the incident response plan should include procedures for communicating with different stakeholders, such as customers, business partners and regulators.
In addition to testing the incident response plan, organizations need ways to evaluate its effectiveness. Measures of performance might include the number of incidents detected and resolved, their respective costs in terms of damages and business interruptions, as well as the duration between identifying and addressing an incident. These metrics can be used to assess the effectiveness of the incident response plan. Furthermore, detailed analysis can help identify trends and patterns in incidents and highlight areas where improvements can be made.
