How can you build a honeypot to strengthen network security?

While honeypots come with some deployment and management challenges, their tangible benefits – ranging from improved threat-detection capabilities to enhanced incident response – provide compelling arguments for an organisation to build up its security framework.

Designed appropriately, a honeypot can therefore serve as a vital ingredient in a holistic strategy for network security, offering savvy insights out of which organisations can create anticipatory measures for the changing threat scenario.

In today’s digital age, the significance of network security can never be overemphasised. Organisations are continually under siege by very sophisticated cyber threats which require a really robust security procedure for protection. One very innovative and effective way to strengthen network security is through deploying honeypots.

A honeypot is defined as a computer system or a program that purposefully exposes itself to outsiders as vulnerable simply to entice attackers. By mimicking valuable assets, the honeypots can help organisations in discovering, analysing, and mitigating any security risks.

Understanding honeypots

Before discussing the application of a honeypot it should first be understood, what is it essentially about? Honeypots are systems that bring cybercriminals into their domain and can act as decoys, luring them away from the real network. Such systems have four main functions:

1. Deception: Legitimate target systems are impersonated by honeypots to engage attackers so that security teams can observe how they conduct themselves.
2. Gathering Data: Honeypots store a wealth of data from attacks on strategies employed in attack, tools used and points of weaknesses that could be exploited.
3. Threat Intelligence: The data thus collected can be used for threat analysis improving overall security posture, through education of teams on the current trends in cybercrime.

Types of honeypots

1. Low-Interaction Honeypots: These are the simple systems that simulate a very few numbers of vulnerabilities. They require very few resources to deploy and are mostly easy to deploy. Mainly they provide the very basic interactions and are used for collecting the data about the automated attacks.
2. High-Interaction Honeypots: High-interaction honeypots are full operating systems and thus present a much more realistic environment to an intruder. These types of honeypots are resource hungry and demand a lot of maintenance but give much in-depth understanding of sophisticated attack methodologies.
3. Research Honeypots: It is primarily used by researchers and organisations interested in studying attack patterns as well as acquiring intelligence for academic or security research purposes.
4. Production Honeypots: These honeypots are integrated into an organisation’s production environment to enhance security through potential baiting of attackers and real-time collection of attack data.

Steps for building a honeypot

1. Define Objectives: Organisations should be able to clearly define the objective for which the honeypot would be deployed. Whether it is for research, threat analysis, or distraction, clear objectives will shape subsequent decisions.
2. Choosing a Type of Honeypot: Based on the objectives, decide on whether to choose a low- or high-interaction honeypot. This will influence the resources required and the levels of detail in the attack data that can be gathered.
3. Design the Environment: Control the environment where the honeypot will reside. Isolation will be vital because it will deny them the opportunity to use the honeypot as a route into the real network. This would mean having the honeypot in a different VLAN, or using some virtualisation technology.
4. Deployment: Once the environment is designed, it is time to deploy the honeypot also. It typically involves configuring the operating system, applications, and vulnerabilities to draw specific types of attacks. Ensure that the honeypot has distinct characteristics that can lure it into the sights of attackers.
5. Monitoring and Data Collection: Provide strong monitoring solutions that have the capacity to capture and perform analysis of the activities occurring in the honeypot. This may include packet-analysing tools, logging of user activities, recording interactions with the system, and so on.
6. Analysis and Response: Data collected through honeypots must be continuously analysed in order to allow identification of trends, emerging threats, and methodologies by which attackers operate. This information would be useful to strengthen the pre-existing security measures within the environment of the actual network.

Advantages of deploying a honeypot

1. Improved Detection: Honeypots may be able to detect threats that currently go unnoticed in traditional detection systems, giving organisations advanced warning of impending infiltrations.
2. Enhanced Incident Response: Organisations gain intelligence about how attackers behave, thereby developing responses that are specific to the attacks and how they strengthen real systems to avoid the attack.
3. Economical Security Strategy: The cost associated with honeypot technologies will be smaller than what will be involved in better traditional security solutions and still return actionable intelligence.
4. Training Security Teams: Contacting real attacker methodologies allows security teams to fortify their working knowledge of threats and enhance their response preparedness by its practice.

Importance of MDM

Mobile devices are increasingly responsible for business activity, necessitating MDM for data security and compliance purposes. One safe strategy is to place a honeypot alongside the MDM for further increased security.

For instance, maximum effect from a honeypot would require MDM integration. MDM solutions are managing mobile devices while being managed to make sure that they are all enrolled, configured, and secured.

Thus, the honeypot should be treated as a separate device within the MDM, allowing through centralised MDM dashboards monitoring and control over it. It helps analyse traffic and alerts generated by the honeypot against the information from other managed devices.

After the installation of honeypots and MDM, the next essential step is continuous monitoring to glean insights that can be fed into the overall security strategy or be used to improve MDM configurations to better safeguard actual devices.

A final consideration is that the creation of a honeypot is not a one-time job. Catching up with the evolutionary threat landscape requires consistent re-examination and revitalisation.

Thus, to keep up with attackers’ new methods, the honeypot design and MDM policies must be modified and adapted.
