Which of the following is an example of an event that may occur during the protect stage of the plan-protect-respond cycle?

The protect stage of the plan-protect-respond cycle involves proactive measures taken to safeguard an organization’s assets from potential threats. This stage includes implementing various strategies and practices to prevent security breaches and ensure the integrity, confidentiality, and availability of information.

Determining levels of access control is a critical aspect of security policy, as it defines who can access specific resources and at what level. This is vital for minimizing unauthorized access and protecting sensitive information.

Performing routine maintenance on organizational resources helps ensure that systems are secure and running optimally. Regular updates and checks can prevent vulnerabilities from being exploited, which is an essential part of maintaining a strong security posture.

Training employees to recognize and respond to potential threats can significantly reduce the risk of incidents and enhance overall security awareness within the organization.

Each of these actions contributes to the protective measures an organization takes, making all of them relevant examples of activities that can occur during the protect stage. Therefore, recognizing that all listed actions contribute to the protective efforts validates the conclusion that the correct choice is indeed all of the above.
