Which of the following is not a typical response when dealing with a risk?

Patching is a specific technical action taken to address vulnerabilities within software or systems, typically aimed at improving security or functionality. While it is an important part of maintaining systems' security posture, it is not categorized as a primary method of risk response in the context of risk management strategies.

On the other hand, avoidance, mitigation, and transfer are established risk management strategies. Avoidance involves altering plans to sidestep potential risks, mitigation entails implementing measures to reduce the impact or likelihood of risks, and transfer means shifting the risk to another party, such as through insurance or outsourcing. These strategies are part of a comprehensive approach to managing risks across various domains, making them typical responses in risk management.

Thus, patching, while critical in a cybersecurity context, is more of a specific action rather than a strategic response to a risk.
