Have you ever wondered how a hacker breaks into a live system? Would you like to keep any potential attacker occupied so you can gather information about him without the use of a production system? Would you like to immediately detect when an attacker attempts to log into your system or retrieve data?
One way to see and do those things is to deploy a honeypot. It’s a system on your network that acts as a decoy and lures potential hackers like bees get lured to honey. Honeypots do not contain any live data or information, but they can contain false information. Also, a honeypot should prevent the intruder from accessing protected areas of your network.
