Honeynet

What is a Honeynet?

A Honeynet is a network of honeypots designed to provide comprehensive monitoring and analysis of cyber attacks across multiple systems, services, and network segments. Unlike individual honeypots, honeynets create a realistic network environment that allows attackers to interact with multiple systems while being monitored and controlled.
