The complete guide to ethical hacking and cybersecurity, from absolute beginner to professional level: 201 pages, 19 chapters. You start from zero — computer basics, networking from A to Z (OSI, TCP/IP, DNS, Wi-Fi), Linux and the command line, Windows, Python for security — then you level up: build your 100% legal training lab (virtual machines), the complete penetration testing methodology, the professional tool families and how to read their results, the OWASP Top 10 explained (how each flaw works AND how to protect against it), cryptography, social engineering (recognizing it to defend yourself), defending like a pro (hardening, backups, detection, incident response), famous case studies and their lessons, and the professional path (Security+, CEH, OSCP certifications, portfolio, legal bug bounty). Chapter 2 sets the legal and ethical framework: here, you learn to test WITH authorization and to protect. Appendices: essential Linux commands, ports table, sample pentest report outline, the hacker's ethical charter to sign. Author: Landry Ngantchui — Best Numerique.
