Final answer:
The proper phase for including measures to limit damage during an ongoing breach is 'Containment, Eradication, and Recovery'. It prevents spread, removes threats, and restores normal operations while helping to develop efficient response strategies.
Step-by-step explanation:
The phase of the incident response process that includes measures designed to limit the damage caused by an ongoing breach is C. Containment, Eradication, and Recovery. During Containment, the focus is on preventing the spread of the breach; Eradication involves removing the threat entirely, and Recovery is about restoring systems and services to normal operations. Other phases of the incident response process include Preparation, where organizations develop their incident response plan and capabilities; Detection and Analysis, where they identify and investigate potential security incidents; and Post-Incident Activity, which is centered around learning from the incident and improving future responses. These steps are crucial for implementing civil defense and emergency preparedness measures, as well as ensuring the resilience of a critical national infrastructure.
