Ethical hacking is legally testing systems for weaknesses before malicious hackers find them. This visual guide covers the hacking phases — reconnaissance, scanning, exploitation, and reporting — plus the legal and authorization rules every ethical hacker follows.

Legally testing systems for weaknesses before attackers find them.

White hats hack with permission; black hats break the law.

Always get written permission before testing.

Think like an attacker to defend better.

Gather public info about the target.

Passive avoids contact; active probes directly.

Find open ports, services, and versions.

Exploit a vulnerability to get in.

Test persistence as a real attacker might.

Understand how attackers hide (for defense).

Document findings and fixes clearly.

Weak passwords, misconfigs, and unpatched software.

Nmap, Burp Suite, Metasploit, and Wireshark.

People are often the weakest link.

Find flaws like injection and broken auth.

Probe firewalls, services, and segmentation.

Practice hacking skills legally and safely.

CEH and OSCP validate ethical hacking skills.

Scope, permission, and disclosure are mandatory.

Practice on legal labs like Hack The Box.
