Master OccupytheWeb. Network Basics for Hackers: How Networks Work and How They Break

InfoSec Press, 2023. — 270 p., il.Following the success of Linux Basics for Hackers, OccupytheWeb does what he did for Linux to Networks. Networks of all types, including TCP/IP, Bluetooth Networks, Car Networks, Wi-Fi networks, Radio Frequency Networks, SCADA/ICS Networks, and more. In his inimitable style, Master OTW makes the seemingly complex, simple. This book is designed for beginner to intermediate cybersecurity professionals. It begins with the basics of networks and networking, examines network analysis with Wireshark and tcpdump, offers one of the most complete and in-depth analyses of Wi-Fi and Bluetooth networks, and then progresses through the various protocols such as DNS, ARP, SMTP, and others. The reader will be led through the building of those applications in Linux, such as an EXIM server for email or a BIND server for DNS. Then OTW leads the reader through the major vulnerabilities of that protocol/application. In the final chapters, OTW leads the reader through some of the networks on the leading edge of cybersecurity, such as Car, Radio, and Industrial networks.Prelude
