IPSs (Intrusion Prevention Systems) can detect zero-day attack if they employ_____________
A) signature-based detection
B) anomaly detection
C) all of the above
D) none of the above

Question

Quizplus · Accepted Answer

Zero-day attacks are attacks that are not known or previously identified by the security system. In signature-based detection, the system identifies attacks based on known patterns or signatures. Hence, it cannot detect zero-day attacks. Anomaly detection, on the other hand, monitors the behavior of the system and can detect deviations from normal behavior, which can indicate zero-day attacks. Therefore, employing anomaly detection in IPSs can help detect zero-day attacks.
