Which concept involves ensuring continuous monitoring of security systems?

The concept of continuous monitoring is a critical component of maintaining security in any organization. It focuses on the ongoing assessment of security policies, configurations, and infrastructure to ensure they are effective and functioning as intended. Continuous monitoring involves real-time surveillance of security systems to detect and respond to vulnerabilities, threats, and incidents as they occur. This proactive approach helps organizations to identify areas requiring attention before they can be exploited by attackers.

By regularly reviewing and analyzing security logs, network traffic, and system behaviors, organizations can gain insights into potential security risks and make informed decisions about how to mitigate them. This fulfills the goal of maintaining a robust security posture that adapts to new challenges and threats, ensuring that security measures remain relevant and effective over time.

In contrast, risk management encompasses a broader range of activities, including the identification, evaluation, and prioritization of risks but does not specifically focus on ongoing surveillance. Defense in depth involves implementing multiple layers of security controls but doesn't inherently require continuous monitoring. Incident response refers to the steps taken after a security incident occurs, rather than the ongoing processes needed to monitor for incidents proactively. Thus, continuous monitoring is the most precise and relevant concept for ensuring that security systems remain vigilant and effective.
