What is a Honeypot?

A honeypot is a deliberately prepared decoy system, service, account, or dataset designed to attract attackers. Its purpose is not to make production systems safe by itself, but to observe attack methods, provide early warning, and improve defensive rules.

For example, an SSH service that appears exposed to the internet may not connect to a real server at all; it records login attempts, usernames, IP addresses, and tools used by attackers.

How Does It Work?

A honeypot can be low-interaction or high-interaction. Low-interaction systems emulate selected service behavior and carry less risk. High-interaction systems provide a more realistic environment, but isolation and monitoring are harder.

Safe use requires separating the honeypot from the production network, preventing it from launching outbound attacks, and forwarding logs to a central monitoring system. A misconfigured honeypot can become a pivot point for an attacker.

Security Use

Honeypots are used to study brute-force attempts, bot behavior, malicious payloads, and new scanning patterns. The signals collected can help improve firewall, IDS, SIEM, or WAF rules.

Unlike a controlled penetration test, a honeypot passively observes real attacker behavior. It is not a standalone protection layer; it should be used together with segmentation, patch management, and access control.
