Designed and implemented a honeypot as part of a cybersecurity project to showcase my skills and expertise. In this project, I strategically deployed a Linux-based honeypot, a simulated system that appears to be a high-value target for cyber attackers. The purpose of the honeypot was to attract and deceive malicious actors, allowing me to gather valuable insights into their attack techniques, tactics, and behavior.

By creating this honeypot, I demonstrated my ability to understand and replicate the appearance and behavior of genuine services, such as web servers or network devices, within a controlled environment. This involved configuring Linux software tools to mimic these services and make them appear attractive to potential attackers.
