What is penetration testing?

Also known as: pen test, pentest, ethical hacking

Definition

Penetration testing is an authorized, simulated attack on a system to find and demonstrate exploitable weaknesses before real attackers do.

Why it matters

Tests have a written scope and permission from the system owner. Unlike automated vulnerability scanning, a tester chains findings together to show real impact, then reports fixes.
