What is the difference between an IDS and an IPS?

Information applies to:

Panda GateDefender Integra 100
Panda GateDefender Integra 300

IDS (Intrusion Detection System) and IPS (Intrusion Prevention System) both increase the security level of networks, monitoring traffic and inspecting and scanning packets for suspicious data. Detection in both systems is mainly based on signatures already detected and recognized.

The main difference between one system and the other is the action they take when an attack is detected in its initial phases (network scanning and port scanning).

  • The Intrusion Detection System (IDS) provides the network with a level of preventive security against any suspicious activity. The IDS achieves this objective through early warnings aimed at systems administrators. However, unlike IPS, it is not designed to block attacks.
  • An Intrusion Prevention System (IPS) is a device that controls access to IT networks in order to protect systems from attack and abuse. It is designed to inspect attack data and take the corresponding action, blocking it as it is developing and before it succeeds, creating a series of rules in the corporate firewall, for example.
