Intrusion
Prevention
System) Software that prevents an attack on a network or computer system. It is a significant step beyond an intrusion detection system (IDS). Whereas an IDS passively monitors traffic by sniffing packets at a switch port, an IPS resides inline like a firewall, intercepting and forwarding packets. It is thus capable of blocking the attack in real time. See
IDS.
