What Does Host-Based Intrusion Detection System (HIDS) Mean?

A host-based intrusion detection system (HIDS) is a system that monitors a computer system on which it is installed to detect an intrusion and/or misuse, and responds by logging the activity and notifying the designated authority. A HIDS can be thought of as an agent that monitors and analyzes whether anything or anyone, whether internal or external, has circumvented the system’s security policy.

Techopedia Explains Host-Based Intrusion Detection System (HIDS)

An intrusion detection system (IDS) is a software application that analyzes a network for malicious activities or policy violations and forwards a report to the management. An IDS is used to make security personnel aware of packets entering and leaving the monitored network. There are two general types of systems: a host-based IDS (HIDS) and a network-based IDS (NIDS).
