Which of the following scenarios BEST describes a risk reduction technique?

The scenario that best describes a risk reduction technique is implementing a policy to train users on a more secure method of operation. Risk reduction involves taking steps to mitigate potential vulnerabilities and decrease the likelihood or impact of security incidents. By providing employees with training, the organization empowers them to recognize and avoid risks associated with insecure practices, thereby enhancing overall security posture. This proactive approach is critical in fostering a culture of security awareness and ensuring that all users understand the importance of following secure methods.

In contrast, the first scenario involving purchasing insurance does not necessarily reduce risk; instead, it transfers it. While insurance is a valid strategy for managing risk, it doesn't diminish the actual vulnerabilities or threats present in the environment.

Changing a method of operation can be relevant to risk management but may not involve a comprehensive strategy focused on reducing risk through preventative measures like training.

Lastly, having the Chief Information Officer sign off on the risk does not actively mitigate or change the risk factors involved; it merely acknowledges them, which may not contribute to a safer operational environment. Thus, investing in training is the most effective method for reducing risks in this context.
