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.

Resources

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.
