Explanation:
A network-based intrusion detection system (NIDS) is used to monitor and analyze network traffic to protect a
system from network-based threats.
A NIDS reads all inbound packets and searches for any suspicious patterns. When threats are discovered,
based on its severity, the system can take action such as notifying administrators, or barring the source IP
address from accessing the network.
