Detailed explanation-1: -Intrusion prevention system Multiple detection systems across a network communicating together to give a better picture of network activity.
Detailed explanation-2: -Answer. Snort is referred to as a packet sniffer that monitors network traffic, scrutinizing each packet closely to detect a dangerous payload or suspicious anomalies.
Detailed explanation-3: -An example of an NIDS would be installing it on the subnet where firewalls are located in order to see if someone is trying to break into the firewall. Ideally one would scan all inbound and outbound traffic, however doing so might create a bottleneck that would impair the overall speed of the network.
Detailed explanation-4: -Signature-Based Intrusion Detection. Signature-Based Intrusion Detection Systems (SIDS) aim to identify patterns and match them with known signs of intrusions. Anomaly-Based Intrusion Detection. Hybrid Intrusion Detection.
