Which of the following actions is important for protecting cyber data against unauthorized disclosures?

Ensuring continuous monitoring is crucial for protecting cyber data against unauthorized disclosures because it allows organizations to detect and respond to potential threats in real time. Continuous monitoring involves the ongoing observation of network activities, user behaviors, and system configurations, which helps identify unusual patterns that may indicate a security breach or insider threat. By implementing systems that can analyze data flows and user actions continuously, organizations can effectively mitigate potential risks and avert unauthorized access to sensitive information.

In contrast, while regularly changing user passwords can enhance security by reducing the likelihood of password compromise, it does not address potential insider threats or provide a comprehensive view of ongoing activities. Restricting access to management only may limit exposure but fails to account for legitimate users who require access for their roles. Similarly, limiting software installations can reduce vulnerabilities but does not specifically enhance the detection or monitoring of unauthorized disclosures. Continuous monitoring addresses these challenges by providing comprehensive oversight and proactive threat detection.
