Every protocol is explained through its real behavior on the wire, and every chapter ends with a hands-on lab using the tools professionals actually use: Wireshark, nmap, tcpdump, curl, dig, iptables, and nftables.You'll master the TCP/IP model, IP addressing, NAT, routing and ARP, TCP/UDP internals, DNS and mail authentication, HTTP/HTTPS and TLS 1.3, remote access (SSH, RDP, VPNs), and the silent protocols keeping every LAN alive: DHCP, NTP, SNMP. The final chapters build a complete diagnostic toolkit and a real firewall, closing with a hands-on virtual lab - client, router, and DMZ server - where every tool in the book comes together.For students, sysadmins, and aspiring security professionals ready to understand what really happens on the wire.", "item_img_path" : "https://covers2.booksamillion.com/covers/bam/9/79/819/279/9798192793893_b.jpg", "price_data" : { "retail_price" : "19.90", "online_price" : "19.90", "our_price" : "19.90", "club_price" : "19.90", "savings_pct" : "0", "savings_amt" : "0.00", "club_savings_pct" : "0", "club_savings_amt" : "0.00", "discount_pct" : "10", "store_price" : "" } }
