One form of Intrusion Detection System (IDS) starts operation by generating an alert for every action. Over time, the administrator adjusts the setting of the IDS so that common, benign activities do not generate alarms. What are the advantages and disadvantages of this design for an IDS

advantages

- detect anomalies

- information for new security rules

disadvantages

- false alarms

Explanation:

Advantages

- With an IDS we can check and track every attack or detect anomalies even when you don't know about these behaviors.

- When an IDS detects anomalies, the system generates information about these behaviors and you can create new rules for these attacks.

Disadvantages

- When we use an IDS, we could receive false alarms because we cannot predict every behavior.
