Linux for security
Why security people love Linux
Most security tools, servers, and labs run on Linux, so comfort at the Linux command line is a core skill. You do not need to be an expert, but you should be able to move around, read files, manage permissions, and run tools.
Learn to:
- Navigate the filesystem (
cd,ls,pwd) - View and search files (
cat,less,grep) - Manage permissions and users (
chmod,sudo), least privilege in action - Install and run tools from the terminal
The fastest way to learn is hands-on, in a real or browser-based Linux environment.

Practice
In any Linux environment (or the labs above), create a folder, create a file inside it, and list the folder's contents. Write down the three commands you used.
