What is Linux?
Linux is a free, open‑source operating system built on the kernel created by Linus Torvalds in 1991.
It comes in countless “distributions,” powering everything from enterprise servers to tiny IoT gadgets.
Open code—audit every piece, compile your own kernel.
Built‑in tools (Bash, awk, sed, netcat) give instant pentesting power.
Package managers install Metasploit, Burp Suite, and more in seconds.
Fine‑grained permissions (sudo, SELinux/AppArmor) make privilege labs easy.
VMs, containers, and live‑USBs turn any box into a throw‑away hacking lab backed by a huge community.
Why is Linux the ultimate ethical hacking environment?
Linux grants full-stack visibility—from kernel to user space—so nothing stays hidden.
Its open tools and tweak‑friendly nature turn every system into a customizable lab.
