It covers data center and enterprise network architecture, L2/L3 topologies, attack surfaces, and protocol structures for Layers 2–4 including tunneling and encapsulation. The book then explains security protocols such as encryption, PKI, authentication, authorization, IPSec, and SSL/TLS, and maps them to practical defensive components and tool-driven vulnerability testing.","Network Protocols for Security Professionals  \nCopyright ©2022 Packt Publishing  \nAll rights reserved.
