IDS

Intrusion Detection System. A system for detecting (unauthorised) intrusions into a network or individual computer.

An Intrusion Detection System will typically either:

• monitor log files to detect intrusions on a single computer. This is known as a Host based IDS (HIDS).
• or, will employ a packet sniffer to monitor network traffic to attempt to detect intrusions on a network. This is known as a Network based IDS (NIDS).
