A honeypot is a deliberately exposed or simulated system designed to attract malicious activity so that it can be observed without putting genuine production services at unnecessary risk. By presenting attackers with convincing targets, honeypot software can record connection attempts, exploit behaviour, credential guessing, malware delivery, scanning activity, and other hostile interactions.
These tools are useful for system administrators, network defenders, security researchers, incident response teams, and anyone interested in understanding how attackers probe and abuse internet-facing services. They can complement firewalls, intrusion detection systems, and log monitoring by providing a controlled environment in which suspicious behaviour is easier to isolate and study.
The software featured here covers several different approaches. Some applications emulate multiple network protocols and services, making them suitable for broad monitoring across an infrastructure. Others focus on capturing malware and exploit attempts, recording usernames and passwords submitted by attackers, detecting abuse of SIP and VoIP services, or monitoring hostile activity directed at web applications.
All of the programs selected are free and open source, allowing administrators to inspect the code, adapt deployments to their own environments, and integrate captured data with wider security monitoring workflows.
Here’s our verdict captured in a legendary LinuxLinks-style ratings chart.
