Building honeypots with vcluster and Falco: Episode I

The text outlines the process of building a simple SSH honeypot using vcluster and Falco for runtime intrusion detection, highlighting the benefits of honeypots in cybersecurity. Honeypots are tools used to lure attackers and gather intelligence on their activities, classified by complexity as low or high interaction. Low interaction honeypots require fewer resources but offer limited insights, while high interaction honeypots provide detailed intelligence but risk giving attackers access to real assets. Virtual clusters offer a solution by creating isolated environments within Kubernetes clusters, allowing secure exposure of sensitive elements without risking the host infrastructure. The text describes setting up a honeypot using Minikube to provision a Kubernetes cluster, followed by deploying Falco for monitoring and an insecure SSH server as the honeypot target. The installation and testing process involves multiple terminal windows to simulate an attack, with Falco detecting unauthorized activities. The guide concludes with cleanup instructions and hints at further exploration in a subsequent episode.
