1. Introduction
As the demand for the Internet in human society continues to grow, cyber security has gradually become the key issue for the further development of the Internet, as well as various online services and applications. Particularly since the commercialization of the Internet began in 1993, there has been a significant increase in e-commerce activities conducted over the Internet. Additionally, as Internet/Intranet technologies continue to mature, many organizations and enterprises have established their internal networks and connected them to the Internet. These e-commerce applications and the trade secrets embedded within corporate networks have become prime targets for attackers.

According to a survey report published by the American business magazine *InformationWeek*, security issues like hacker attacks and viruses caused economic losses exceeding trillions of dollars in the year 2000. Globally, a cyberattack was reported to occur every few seconds. The summer of 2003 was nothing short of a nightmare for the countless hosts running Microsoft Windows—a time that left a lasting sad memory for Internet users. All this was attributed to the worldwide spread of the Blaster Worm.

2. The Development Background of Honeypot Technology
The core challenge of network and information security technology is to effectively safeguard computer systems and networks. Network security protection encompasses a broad range of aspects, and from a technical perspective, it primarily includes firewall technology, intrusion detection systems (IDS), virus prevention tools, data encryption, and authentication techniques.

Most of these technologies adopt a passive approach, reacting only when an attacker initiates an assault on the network. Honeypot technology, however, takes a proactive stance. As the name implies, a honeypot attracts attackers with certain unique characteristics while analyzing their behavior to devise effective countermeasures.

(Some might wonder if actively attracting attackers equates to inviting trouble. But I argue: if attackers don’t target you, how can you attract them? To frame it differently, this can be considered “luring the enemy deeper.”)

3. The Concept of Honeypots
Here, we introduce the concept of honeypots. A notable expert in honeypot technology, L. Spizner, described a honeypot as “a resource whose value lies in being probed, attacked, or compromised.” This means that a honeypot is designed to be discovered, attacked, and possibly breached. Unlike traditional security measures, it doesn’t fix anything actively—its purpose is to provide valuable, supplementary insights to its operator.

Honeypots don’t directly improve network security but serve as an indispensable form of active defense, complementing other security strategies.

Specifically, the most critical role of a honeypot system is to monitor and record all operations and behaviors within the system. Security experts can design honeypots to appear as legitimate targets, tricking attackers into thinking their actions are undetected. To lure them, honeypots often include backdoors or plant fake sensitive information—items attackers would typically seek.

Some systems even record attackers’ chat sessions. By analyzing these logs, administrators can uncover the tools, methods, goals, and skill levels of attackers while gaining insight into their range of activities and potential targets. Additionally, such data could serve as evidence in prosecuting offenders. While honeypots don’t replicate real systems entirely, they can create an environment that detains attackers within a simulated or isolated system. The effectiveness of a honeypot lies in its ability to attract and engage attackers.

4. Classification and Security Value of Honeypots
Since the inception of computer networking, researchers and security professionals have employed diverse honeypot tools. Based on different standards, honeypots can be classified in several ways. As mentioned earlier, deploying honeypot technology is primarily driven by its security value. However, it’s important to note that honeypots cannot replace traditional security tools like firewalls and intrusion detection systems. Here, let’s examine the security value of honeypot technology in detail.

# Based on Design Purpose:
Honeypots can be divided into two categories: production honeypots and research honeypots.

1. Production Honeypots
Typically used in commercial organizations, production honeypots aim to reduce the threat of attacks that organizations face. They work by bolstering the organization’s security measures, primarily detecting and handling malicious attackers.

– These honeypots contribute minimally to defense—they don’t prevent attackers from attempting to breach the system. In fact, their design intends for attackers to compromise the honeypot system, enabling better analysis and recording of their actions.
– Despite having weak protective features, production honeypots excel in detection. Extracting suspicious behaviors amidst vast system logs can be challenging for administrators, and even with an IDS in place, false positives and missed alarms can overwhelm response teams. Honeypots minimize false positives significantly. Since the honeypot itself offers no legitimate services, any connection to it is likely to be reconnaissance, scanning, or an attack, streamlining the detection process. This makes production honeypots increasingly sophisticated tools for security monitoring.
– If an organization’s internal systems are compromised, affected systems can’t typically operate offline without impacting services. On the other hand, production honeypots can respond to intrusions as sacrificial systems, operating independently and enabling system administrators to analyze incidents offline without disrupting regular operations.

2. Research Honeypots
Research honeypots are developed to study and gather information on cyberattacks. Their focus isn’t to enhance any specific organization’s security but rather to expose a research organization to network threats. By collecting data on malicious activities, researchers have an opportunity to study and develop better ways to counter threats. These honeypots are widely used in the military and security research institutions.

# Based on Interaction Levels:
Honeypots can also be classified into low-interaction, medium-interaction, and high-interaction honeypots, reflecting the three stages of honeypot evolution:

1. Low-Interaction Honeypots
These honeypots simulate systems and services but do not actually provide full functionalities. They are the safest option as they only respond minimally, and while attackers may interact with them briefly, the amount of data gathered is relatively limited.

2. Medium-Interaction Honeypots
These simulate a real operating system and its behaviors more comprehensively, providing attackers greater levels of interaction. Medium-interaction honeypots also extract more data about attacker methods and tools.

3. High-Interaction Honeypots
High-interaction honeypots provide attackers with a fully functional operating system. They’re the most realistic targets and can gather the most detailed information about attacker behavior post-compromise. However, they are high-risk; if an attacker completely breaches such a honeypot, it can become a launching pad for further attacks.
