What must you know before you can be a white hat hacker?

Answer 1

Before you can be a white-hat hacker, you must understand and commit to the legal and ethical framework that separates authorized security testing from wrongdoing—always obtain explicit written permission and follow responsible-disclosure practices. Technically, you need strong foundations in networking (TCP/IP, DNS, routing), operating systems (especially Linux and Windows internals), and one or more programming or scripting languages (Python, Bash, PowerShell, or C) to write and modify tools or exploit proofs-of-concept.

Learn core security concepts—cryptography, authentication, access control, web and application vulnerabilities (OWASP Top 10), and common attack techniques such as SQL injection, XSS, and privilege escalation. Familiarize yourself with standard tools and platforms (e.g., Nmap, Metasploit, Burp Suite, Wireshark) and practice in safe, legal environments like CTFs, labs, and virtual testbeds. Obtain formal training or certifications (such as OSCP, CEH, or equivalent practical courses) to validate skills and best practices, and build strong reporting, documentation, and communication abilities so findings are clear, reproducible, and actionable for stakeholders. Finally, maintain continuous learning—security is dynamic—adhere to professional ethics, and never test systems without authorization.
