Find Your Weak Spots Before Hackers Do: Scan & Secure Your Own Network with Nmap

By Jacob Francis

Find the open door before a thief does - and close it.

This is your first hands-on, active step as a guardian: scanning. This third book in the Ethical Hacking & Cyber Security Series takes you there gently, using Nmap, the world's most trusted free tool.

You will learn to quietly check your own machine for open doors, see who stands behind each one and how old its lock is, and then close the gaps you do not need. A complete Quick-Start builds you a safe lab with a practice target, so you can do every scan yourself - safely and lawfully, only ever on what is yours - even if this is your very first book. Every step comes with a hands-on Guided Practice.
