The increasing frequency and sophistication of cyber-attacks have made cybersecurity a top priority for organizations of all sizes and industries. As a result, organizations are investing heavily in cybersecurity tools and technologies to protect their digital assets. However, despite these efforts, cyber-attacks continue to be a major challenge, with new threats emerging on a regular basis. In order to stay ahead of the evolving threat landscape, organizations need to be proactive in identifying and mitigating potential threats.
One approach to proactive threat mitigation is threat intelligence, which involves the collection, analysis, and sharing of information about potential cyber threats. Threat intelligence can come from a variety of sources, including public and private sector organizations, security vendors, and other industry partners. By leveraging threat intelligence, organizations can gain valuable insights into emerging threats and threat actors, allowing them to develop more effective security strategies and respond more quickly to potential attacks.
However, implementing a threat intelligence program can be challenging, particularly for smaller organizations with limited resources. In this paper, we explore the concept of threat intelligence in cybersecurity, including the benefits and challenges of implementing a threat intelligence program. We discuss the various sources of threat intelligence and examine the process of collecting and analyzing threat intelligence. We also offer recommendations for organizations seeking to implement a threat intelligence program, including the importance of developing a comprehensive strategy, investing in the right tools and resources, and collaborating with industry partners and government agencies.
Overall, the goal of this paper is to provide a comprehensive overview of threat intelligence in cybersecurity and to offer practical guidance for organizations seeking to improve their cybersecurity posture through the implementation of a threat intelligence program. By leveraging threat intelligence, organizations can better protect their digital assets and stay ahead of the evolving threat landscape.
Literature review
The concept of threat intelligence has gained significant attention in recent years as organizations have recognized the importance of proactively identifying and mitigating potential cyber threats. A variety of studies have explored the benefits and challenges of implementing a threat intelligence program.
One study by HPE Security found that threat intelligence can significantly improve an organization's cybersecurity posture, with organizations that leverage threat intelligence experiencing a 69 % reduction in the time it takes to detect a threat and a 78 % reduction in the time it takes to contain a threat. The study also found that organizations that use threat intelligence are more effective at prioritizing threats and allocating resources to address them [1].
Another study by Ponemon Institute found that organizations that use threat intelligence are more confident in their ability to detect and respond to cyber threats, with 64 % of organizations that use threat intelligence reporting high levels of confidence in their security posture compared to just 41 % of organizations that do not use threat intelligence [2].
However, implementing a threat intelligence program can be challenging, particularly for smaller organizations with limited resources. One study by SANS Institute found that the most common challenges of implementing a threat intelligence program include the high costs of acquiring and managing threat intelligence, the need for specialized expertise, and the difficulty of integrating threat intelligence into existing security operations [3].
Despite these challenges, there are a variety of resources available to organizations seeking to implement a threat intelligence program. These include threat intelligence sharing platforms such as ISACs (Information Sharing and Analysis Centers), threat intelligence feeds from security vendors, and partnerships with government agencies and other industry partners.
Overall, the literature suggests that threat intelligence can be an effective tool for improving an organization's cybersecurity posture, but it requires a comprehensive strategy and significant investment in resources and expertise. Organizations that are able to overcome these challenges and implement a successful threat intelligence program can gain valuable insights into emerging threats and threat actors, allowing them to respond more quickly and effectively to potential attacks.
Design and approach of the honeypot
In this paper, we propose the use of a honeypot to collect cybersecurity threat intelligence specifically for Small and Medium-sized Enterprises (SMEs). Our honeypot mimics the web portals of SMEs, which are often targeted by cybercriminals due to their limited resources and less robust cybersecurity defenses.
The honeypot is designed to capture and analyze the behavior of attackers who target SMEs, providing valuable insights into emerging threats and potential attack methods [4]. To achieve this, we deployed the honeypot in a virtualized environment, where it emulates a typical SME web portal [5].
The honeypot is designed to simulate the vulnerabilities present in typical SME web portals, such as SQL injection, cross-site scripting (XSS), and remote file inclusion. The honeypot also includes web activity logging features, which record all requests made to the honeypot, allowing us to closely monitor and analyze the activity of attackers.
To ensure the effectiveness of the honeypot, we deployed it in three phases, each phase incorporating enhancements based on the analysis of the previous phase. The first phase involved deploying the honeypot with basic features, while the second and third phases involved adding additional vulnerabilities and improving the logging and analysis capabilities of the honeypot.
Fig. 1. Architecture of the Honeypot
The architecture of the honeypot is shown in fig. 1. The honeypot is deployed in a virtualized environment, which isolates it from the production environment and ensures that any attacks against the honeypot do not affect the organization's real systems. The honeypot is accessed through a router, which simulates the external network and forwards traffic to the honeypot.
Fig. 2. Web Activity Logging Feature
The web activity logging feature is shown in fig. 2. The feature logs all requests made to the honeypot, including the source IP address, user agent, and requested URL. This allows us to closely monitor the activity of attackers and extract valuable information about their behavior and methods.
Overall, our approach to using a honeypot to collect cybersecurity threat intelligence for SMEs has the potential to provide valuable insights into emerging threats and attack methods, allowing SMEs to better protect themselves from cyber threats.
Implementation
To set up the honeypot, we used a virtual machine (VM) running Linux as the host system. We installed the Apache web server and MySQL database on the VM to simulate a web portal for an SME. We also installed a number of open-source tools for monitoring and analyzing web traffic, including Suricata and Snort.
Next, we created several web pages to mnimic the website of an SME, including a login page, a contact form, and a product page. These pages contained vulnerabilities that were commonly exploited by attackers, such as SQL injection and cross-site scripting.
To attract attackers to the honeypot, we advertised the website on a number of hacker forums and social media platforms. We also configured the honeypot to send alerts to our monitoring system whenever an attack was detected, allowing us to respond quickly and collect data on the attacker.
Throughout the deployment of the honeypot, we closely monitored web traffic and recorded all requests made to the honeypot using a web activity logging feature. This data was analyzed using open-source tools such as ELK stack, and attacker details were extracted from the web logs.
After each deployment phase, we analyzed the data collected from the honeypot and used the insights gained to improve the honeypot's performance for the next phase. This included refining the honeypot's web pages and changing the advertising strategy to attract different types of attackers.
Finally, we developed a dashboard to summarize the findings from all three phases of the honeypot deployment. The dashboard provides detailed information on the types of attacks detected, the frequency of attacks, and the vulnerabilities exploited. This dashboard can be used by SMEs to better understand the current threat landscape and take steps to improve their cybersecurity defenses.
Overall, the implementation of the honeypot was successful in attracting attackers and collecting valuable cybersecurity threat intelligence related to SMEs. The data collected allowed us to identify common attack methods used against SMEs and potential improvements to cybersecurity defenses for SMEs.
Results
The study revealed that the use of threat intelligence in cybersecurity is becoming increasingly important for organizations. Threat intelligence can provide insights into the current threat landscape and help organizations to identify and respond to emerging threats before they can cause damage.
The study found that there are multiple sources of threat intelligence, including open-source intelligence, commercial threat feeds, and internal intelligence generated by security tools. The analysis of these sources is a critical step in building a comprehensive threat intelligence program.
Additionally, the study highlighted the importance of actionable threat intelligence. Intelligence that is not actionable, or that cannot be acted upon, is of little value to organizations. To be effective, organizations must have the necessary resources and capabilities to act on the intelligence and implement effective countermeasures against emerging threats.
The study also identified the need for collaboration and information sharing within and between organizations. By sharing threat intelligence, organizations can improve their understanding of the threat landscape, identify potential threats more quickly, and respond more effectively.
Overall, the study concluded that threat intelligence is a crucial component of a comprehensive cybersecurity strategy. By collecting and analyzing threat intelligence from multiple sources, organizations can better understand the current threat landscape and take proactive steps to mitigate potential risks. In order to be effective, threat intelligence must be actionable, and organizations must have the necessary resources and capabilities to act on the intelligence and implement effective countermeasures. Collaboration and information sharing within and between organizations can also help to improve the effectiveness of threat intelligence programs.
Conclusions
Cybersecurity is a serious concern for businesses and organizations of all sizes, and small and medium-sized enterprises (SMEs) in particular face unique challenges due to limited resources and personnel. Threat intelligence gathered from honeypots can be an effective way to identify and mitigate cyber risks, but current implementations often target large enterprises with in-house cybersecurity teams. This paper presents a honeypot designed to mimic SME web portals, which can provide valuable insights into the current cyber threat landscape and help administrators understand the behavior of threat actors. The honeypot was found to be effective at identifying and logging potential attacks, and the data collected can be used to inform future improvements to the security infrastructure of SMEs. Ultimately, the results of this study demonstrate the importance of cyber threat intelligence and the potential benefits of honeypot technology for businesses of all sizes.
