What is the purpose of Detection in Depth?

The purpose of Detection in Depth is fundamentally about enhancing security monitoring through the provision of alarms and logs. This concept emphasizes the implementation of multiple layers of security controls that work together to identify and respond to threats. By generating alarms and maintaining logs, an organization can obtain actionable insights into potential breaches or suspicious activities across different areas of the system.

Effective detection mechanisms are crucial for timely responses to security incidents, allowing for enhanced situational awareness and improving an organization's overall cybersecurity posture. This proactive approach ensures that even if one security layer fails, others remain operational to monitor for threats.

In contrast, focusing solely on perimeter security would neglect the many vulnerabilities that exist beyond the initial barrier. Simplifying incident response processes does not inherently fulfill the primary goal of Detection in Depth. Furthermore, it is impossible to eliminate all security threats completely; the objective is to detect and manage them effectively, which highlights why the emphasis on alarms and logs is essential to the integrity of security operations.
