Overly basic Ubuntu 16/18/20 hardening script I made in 2021-22 for CyberPatriot. Because I am no longer a competitor, this script has been made open for anyone to reference and improve from.
- Download uScript.sh in your sandbox.
- Read it from start to finish before running.
- Once you are ready, run "sudo bash uScript.sh" in the same directory as the script.
- If the script breaks something that wasn't accounted for, restart your image.
