The computing media is starting to use the term IPS (Intrusion Prevention System) more and more, as a replacement for "traditional" IDSs or to make a distinction between them.
An IPS is a system for preventing intrusions and protect against them, not just recognising and reporting them like most IDSs. There are two main characteristics which distinguish a (network) IDS from a (network) IPS:
- The IPS sits inline on the IPS network, and does not just passively listen to the network like an IDS (traditionally placed as a sniffer on the network).
- The IPS has the ability to immediately block intrusions, no matter what transport protocol is used and without reconfiguring a third-party device, which means that the IPS can filter and block packets in native mode (by dropping the connection, dropping offending packets, blocking the intruder, etc.).
