What is a "True Positive" in the context of intrusions?

A "True Positive" refers to a scenario where an actual attack is correctly identified and flagged by a security system. This means that the intrusion detection or prevention system (IDS/IPS) has successfully recognized malicious activity, preventing potential harm to the organization or network.

This concept is pivotal in the field of cybersecurity, as accurately identifying real threats is essential for maintaining a secure environment. A true positive indicates the effectiveness and reliability of the security measures in place. Recognizing and responding to genuine threats helps ensure that resources are allocated appropriately and that systems remain secure against intrusions.

In contrast, other options illustrate scenarios that don't align with the definition of a true positive. For instance, misidentifying normal activities or having an undetected attack does not contribute to effective threat management and can lead to vulnerabilities. Therefore, understanding true positives is crucial for evaluating the performance of security systems and improving overall security strategies.
