Question

Name and define two ways an IDS connects to a network.

Answer 1

Answer:

The two ways an IDS connects to a network are:

1. Signature-based detection uses patterns by establishing a unique identifier for the detection of future cyber attacks, using the IDS sensors and consoles.

2. Statistical anomaly-based detection, as an expert system, relies on the identification of anomalies in the network traffic by comparing against established baselines.

Explanation:

Organizations use the Intrusion Detection System (IDS) as a software program to detect a computer network attack in an effort to stop the attack.  The program analyzes the network traffic for signatures of known cyberattacks and the delivery of network packets.  There are two types: NIDS and HIDS.  Whereas a Network Intrusion Detection System (NIDS) is designed to support multiple hosts, a Host Intrusion Detection System (HIDS) is set up to detect illegal cyber actions in a host's operating system files.
