Building honeypots with vcluster and Falco: Episode I

Honeypots are, at a high level, mechanisms for luring attackers in order to distract them from legitimate access or to gather intelligence on their activities. We’re going to build a small example here of a honeypot using vlcuster and Falco.

This article provides a comprehensive guide to setting up a honeypot using Falco and SecureCodebox. It begins by introducing the concept of virtual clusters and how they can be used for security research. It then explains how to install SecureCodebox and Falco in the host cluster, and how to create a vcluster to run the honeypot. After that, it explains how to use kubectl to examine the different contexts and resources in the cluster. Finally, it provides instructions on how to test the honeypot by using three different terminal windows. In the first terminal, a port forward is used to expose the ssh server to the local machine. In the second terminal, the ssh service is accessed using the credentials provided. In the third terminal, the logs from the Falco pod are viewed. By viewing the /etc/shadow file, a Falco rule is triggered and the intrusion is detected.

Once the virtual cluster is set up, researchers can use Falco to detect any suspicious activity. Falco will generate a Notice Redirect stdout/stdin to network connection rule, as a result of the port forwarding, and a Warning Sensitive file opened for reading by non-trusted program rule fire, as a result of taking a peek at /etc/shadow. This allows researchers to observe the behavior of malicious actors and detect any suspicious activity.

The article also provides instructions on how to clean up the mess made by the setup, and provides some ideas for further enhancements. Researchers can uninstall Falco and their ssh server, clean out minikube, and tidy up any temp files they might have created. They can also add a response engine using Falco Sidekick, add more honeypot bits in a second virtual cluster, and tweak their vcluster configuration to make it more secure.

In conclusion, virtual clusters are a powerful tool for security research, and this article provides a step-by-step guide to setting up a virtual cluster for use in honeypots and security research. It explains how to set up a virtual cluster using Minikube and Falco, how to configure port forwarding and take a peek at the /etc/shadow file, and how to clean up the mess made by the setup. It also provides some ideas for further enhancements, such as adding a response engine using Falco Sidekick, adding more honeypot bits in a second virtual cluster, and tweaking the vcluster configuration to make it more secure. With this guide, users can easily set up
