Definition Edit

A host-based intrusion detection and prevention system (IDPS) is a hardware or software product that provides complementary security services to a personal firewall, monitoring and analyzing the internal state of a client device.

Overview Edit

IDPS products review logs to ensure that the system and applications are not functioning unexpectedly, such as applications inexplicably accessing or altering other portions of the system. Several host-based IDPS software products also monitor inbound and outbound network communications and report or possibly block suspicious activity.
