Which of the following is part of the containment phase in incident response?

The containment phase in incident response is critical in managing the fallout from an incident and preventing further damage. Implementing security measures serves as a proactive approach to limit the scope and impact of an incident that has already occurred. This includes actions such as isolating affected systems, blocking malicious traffic, or applying patches to exploit vulnerabilities to secure the environment.

By focusing on containment, organizations aim to stabilize the situation before moving on to further analysis or recovery. This helps to ensure that the damage does not escalate and aids in a more controlled response to the incident.

In contrast, examining theories, collecting evidence, and assessing impact are activities typically associated with other phases of incident response. For instance, examining theories may take place during the identification phase when teams are trying to understand the nature of the incident. Collecting evidence is usually part of the investigation phase, which follows containment, as it involves gathering information for analysis and potential legal actions. Assessing impact often occurs alongside or after the containment phase to evaluate the consequences of the incident on the organization and its operations.
