Which of the following is a key consideration in security planning for an intrusion detection installation?

In security planning for an intrusion detection installation, a fundamental aspect is the coverage of vulnerable areas. This is crucial because an effective intrusion detection system (IDS) is designed to identify and alert on potential security breaches where threats are most likely to occur. Identifying and prioritizing these vulnerable areas—such as entry points, high-value assets, and regions with a history of incidents—ensures that the system is focused on the most critical aspects of security.

By concentrating on vulnerable areas, you can allocate resources effectively, optimizing the installation to detect unauthorized access while minimizing blind spots. This targeted approach enhances the overall effectiveness and reliability of the intrusion detection system, ensuring that it can respond promptly to threats in regions that pose the greatest risk.

While considerations such as maximum system cost, customer preferences, and the brand of equipment are important in the overall context of an intrusion detection strategy, they do not directly influence the effectiveness of threat detection in the way that assessing and ensuring coverage of vulnerable areas does. This prioritization leads to a more robust security posture.
