Host-based intrusion detection system(HIDS)

Detailed explanation-1: -A host-based IDS is an intrusion detection system that monitors the computer infrastructure on which it is installed, analyzing traffic and logging malicious behavior. An HIDS gives you deep visibility into what’s happening on your critical security systems.
Detailed explanation-2: -Host-based IDS runs on a host and monitors system activities for signs of suspicious behavior. Examples could be changes to the system Registry, repeated failed login attempts, or installation of a backdoor.
Detailed explanation-3: -NIDS and NIPS A network-based intrusion detection system (NIDS) detects malicious traffic on a network. NIDS usually require promiscuous network access in order to analyze all traffic, including all unicast traffic.
Detailed explanation-4: -Host-based IDSs are designed to monitor network traffic and computers, whereas network-based IDSs are only designed to monitor network traffic. There are other nuances between these IDSs, so you should learn the differences between them to determine which IDS type is right for your business’s cybersecurity needs.
