Kali Linux

Learn ethical hacking and penetration testing the way professionals actually practice it: with authorization, evidence and clear reporting.

This second edition is a hands-on guide to Kali Linux for system administrators, security analysts, penetration testers and anyone preparing for a career in cybersecurity. Every lab is designed for systems you own or are authorized to test, and every terminal example is clearly labeled so you always know what is a recorded result and what is an illustration.

Inside you will learn how to:
- Install, update, troubleshoot and harden Kali Linux safely
- Master the Linux command line, networking, DNS and TLS diagnostics
- Run authorized host discovery and service enumeration with Nmap
- Validate vulnerabilities instead of trusting scanner output
- Test web applications and APIs, including object-level authorization
- Assess wireless, Bluetooth, Active Directory, cloud and container environments
- Collect evidence, perform Linux forensics and memory analysis with Volatility 3
- Respond to incidents and verify recovery
- Use AI tools responsibly as an assistant, never as an unaccountable attacker
- Write professional reports with clear remediation and retest criteria

The book closes with more than 100 practitioner questions and answers for administrators, penetration testers and aspiring ethical hackers, including common interview questions, plus 15 appendices of command references, troubleshooting guides, templates and field labs.

Whether you are starting out or sharpening professional skills, this guide teaches you to think like an attacker and defend like an engineer, legally, carefully and with evidence.
