What is IDS?

An Intrusion Detection System (IDS) is a security system that monitors network traffic for malicious activity or policy violations. When suspicious activity is detected, the IDS generates alerts. It's like a burglar alarm for your computer network, but instead of detecting physical intrusions, it looks for unauthorized or malicious activities. Unlike Intrusion Prevention Systems (IPS), IDS typically only detect intrusions and do not actively block or prevent them.
