Which of the following factors is NOT a component of incident impact assessment?

In the context of incident impact assessment, the key components typically include factors that directly relate to the effect the incident has on the organization’s information security and operational capability. Confidentiality refers to the potential loss of sensitive information and the implications that has for the organization. The cost of response encompasses the financial resources that may be necessary to address the incident. Additionally, the duration of the incident highlights how long the incident persists, which can influence the extent of the impact on operations and reputation.

Staff performance, while important to the overall management and response to an incident, does not directly measure the impact of the incident itself on the organization’s systems, data, or resources. Instead, it relates more to the efficiency and effectiveness of the incident response team in handling the situation. Thus, it is not considered a core component of an incident impact assessment, making it the correct choice in this scenario.
