Businesses can run penetration testing using Kali Linux as a Docker container, eliminating the need for a full operating system installation. By deploying Kali Linux as a Docker container, security staff or administrators can easily access a headless container and utilize the wide range of pen-testing tools available. The process involves installing Docker, pulling the Kali Linux image, deploying the container, and installing the necessary pen-testing tools. The resulting container can be saved and reused for future testing, making it a flexible and efficient method for conducting penetration testing.
