Which evaluation correctly identifies a situation where an attacker was recognized by an IDS?

In the context of Intrusion Detection Systems (IDS), a true positive occurs when the system correctly identifies an attacker or malicious activity. This means that the IDS has recognized a legitimate threat, confirming that an intrusion attempt is indeed happening. The accurate detection of an attacker allows the organization to take appropriate actions to mitigate the potential damage caused by the intrusion.

Recognizing an attacker as a true positive is critical for the overall security posture of an organization. It ensures that the security team can respond promptly to real threats, thereby minimizing risks and protecting sensitive data or system integrity. This distinction is vital for evaluating the effectiveness of security measures and contributes to continuous improvement in an organization’s defense strategies.
