Getting started legally
Understand the legal and ethical framework
Ethical hacking means testing systems only with explicit written permission. Bug bounty programs, CTF competitions, and lab environments are all legal. Never scan or probe a system you don't own or have a signed authorisation for.
Set up a practice environment
Kali Linux in VirtualBox or VMware, and deliberately vulnerable practice machines: Metasploitable, DVWA, or TryHackMe's guided labs. Keep your practice environment isolated from your home network.
Learn networking fundamentals
TCP/IP, the OSI model, DNS, HTTP/S, IP addressing, and ports. Most attacks exploit protocol misconfigurations. You can't understand attacks without understanding the protocols they target.
Professional contribution
Complete OSCP preparation
The Offensive Security Certified Professional is the industry-standard practitioner certification. A 24-hour hands-on lab exam with a written report. The preparation process — 90 days in the Offensive Security lab — is as valuable as the certificate.
Report a bug bounty finding
A valid, well-documented vulnerability report submitted to a bug bounty program. The quality of your report — reproduction steps, impact assessment, suggested remediation — matters as much as finding the vulnerability.
