Essential Linux Environments
To master DevSecOps, you need a controlled environment. We will use a headless Linux distribution (Ubuntu or Debian).
Basic Hardening during Setup:
- Use non-root users with
sudoprivileges. - Update all packages immediately:
sudo apt update && sudo apt upgrade -y. - Install essential CLI tools:
git,curl,vim,wget.
Exercise:
Create a new user named secops and disable the root login via SSH in the next lesson.
