Definitions for "Intrusion Detection System"
Hardware and software designed to monitor enterprise networks for unusual behaviour that warns of an attack in progress. Can be host-based or network-based.
combination of hardware and software products that are used to analyze network traffic passing through a single point on the network. The software analyzes the data searching for specific signatures (known patterns of traffic) of malicious intent. More sophisticated systems are capable of taking immediate action to terminate connection, to send an alert to an attendant or to log activity.
