IPS vs. IDS: 5 Differences and How to Choose

What Is IDS (Intrusion Detection System) and How Does It Work?

An intrusion detection system (IDS) is a network security solution that monitors traffic for suspicious activity and alerts security teams when such activity is detected. They aim to stop network attacks before they can compromise a network.

IDS operates by identifying traffic that deviates from normal activity, or exhibits known attack patterns. These deviations or exceptions are flagged, and examined at the protocol and application layers.

IDS can be network-based or host-based. A network-based intrusion detection system is deployed in a network and protects multiple hosts, while host-based IDS is installed on a specific host machine and protects only that host. Another option is cloud-based IDS, which can protect data and systems in cloud environments.

What is IPS (Intrusion Prevention System) and How Does it Work?

An Intrusion Prevention System (IPS) is a network security and threat prevention tool. The main goal of an IPS system is to identify potential threats and rapidly respond. IPS systems can scan network traffic for signs of attack and prevent exploits of vulnerabilities.

An IPS system continuously monitors a network to identify malicious activity, logs detected threats, reports them, and immediately takes action to....
