Final answer:
Patching is a part of the 'Protect and Defend' category in Incident Response on the CompTIA, and involves updating software to fix vulnerabilities. It is often part of the recovery phase in Incident Response, aiming to prevent future threats.
Step-by-step explanation:
In Incident Response, patching is a critical activity that falls under the CompTIA category of 'Protect and Defend.' Patching refers to the process of updating software to fix vulnerabilities that could be exploited by attackers. It is part of the mitigative steps taken to prevent potential threats or to remedy the vulnerabilities that have already been exploited in an incident. In the context of Incident Response, patching is typically part of the recovery phase, where efforts are made to restore systems to normal operation while strengthening them against future attacks. Due to the continually evolving nature of threats, patch management is an ongoing process in cybersecurity.
