What is a primary role of an Intrusion Detection System (IDS) in identifying threats?

To prevent all types of intrusions automatically

To identify abnormal traffic patterns indicating potential threats (correct)

To solely rely on known signatures of past attacks

To completely eliminate false positives during monitoring

How can an IDS contribute to identifying vulnerabilities?

By substituting traditional firewalls

By conducting regular software updates

By permanently blocking all intrusion attempts

By monitoring attempts to exploit known weaknesses (correct)

What is a significant limitation of an IDS?

It may generate false positives that require manual verification (correct)

It always provides immediate resolution to detected threats

It can create a comprehensive protection against all threats

It is capable of stopping intrusions before they occur
