Bash Script Locks Down Ubuntu Server So Hard Even SSH Feels Left Out

A comprehensive Bash script has been developed to secure a fresh Ubuntu server, preparing it for production workloads with essential foundations. The script installs Docker and Docker Compose, as well as a UFW firewall and Fail2Ban for SSH protection. Additionally, it updates the system and installs the Fish shell, improving the overall shell experience. The script secures SSH with UFW and rate limiting, protecting against brute-force attacks using Fail2Ban. By implementing these security measures, users can ensure a secure environment for their Ubuntu server. The script is particularly significant in the context of the growing demand for secure cloud infrastructure, with companies like Docker and Ubuntu playing a crucial role in providing reliable solutions. The use of UFW and Fail2Ban provides an additional layer of protection, with features like rate limiting and banaction, to prevent unauthorized access. This script is a valuable resource for system administrators and developers looking to secure their Ubuntu servers.
