A properly designed and deployed network intrusion detection system and network intrusion prevention system can help block intruders who aim to steal sensitive data, cause data breaches, and install malware. Detecting an intrusion depends on having a clear understanding of network activity and common security threats. What is a Network Intrusion?Ī network intrusion is any unauthorized activity on a computer network. In this article, we outline the characteristics of an intrusion, the various attack vectors cybercriminals can use to compromise network security, the definition of IDS/IPS, and how they can protect your network and improve cybersecurity. However, it’s important to note that both IDS and IPS can implement the same monitoring and detection methods. In short IDS and IPS have the ability to detect attack signatures with the main difference being their response to the attack.

IDS are used to monitor networks and send alerts when suspicious activity on a system or network is detected while an IPS reacts to cyberattacks in real-time with the goal of preventing them from reaching targeted systems and networks.

IDS won't alter network traffic while IPS prevents packets from delivering based on the contents of the packet, similar to how a firewall prevents traffic by IP address. The main difference between intrusion detection systems (IDS) and intrusion prevention systems (IPS) is that IDS are monitoring systems and IPS are control systems.
