This article uses a vivid courtyard analogy to explain core networking concepts such as gateways, DNS, DHCP, routing, static and dynamic routes, ARP spoofing, DDoS attacks, IP/MAC addressing, and security measures, making complex topics easy to grasp.
The article explains how increasing network attacks such as ARP spoofing, DoS, and DNS hijacking exploit vulnerabilities in the four TCP/IP layers, describes their mechanisms, impacts, and defensive measures, and highlights the importance of packet analysis for security.
This guide demonstrates how to use Python's Scapy library to extract IP addresses from PCAP files, sniff usernames and passwords from mail traffic, discover live hosts via SYN packets, launch MAC address table flooding attacks, and conduct ARP spoofing for man‑in‑the‑middle attacks, providing complete code examples.
This article introduces the Netwox network tool suite, explains its installation and extensive command modules, demonstrates how to perform ARP cache poisoning and TCP SYN flood attacks with concrete code examples, and highlights the importance of responsible usage in network security testing.
The article uses a courtyard and gatekeeper metaphor to explain the roles of gateways, DNS, DHCP, routing tables, static and dynamic routing, route selection, IP/MAC addressing, ARP spoofing, DDoS/DoS attacks, and related security concepts in computer networking.
This article explains the MAC learning and aging processes, demonstrates MAC flooding and ARP spoofing attacks with practical test setups, and provides step‑by‑step configurations such as port security, access management, and DHCP snooping to protect network switches from these threats.
The article provides a comprehensive overview of traffic hijacking methods—from legacy hub sniffing and MAC spoofing to DNS poisoning, router CSRF, PPPoE phishing, and Wi‑Fi hotspot attacks—explaining how each works, real‑world examples, and practical mitigation steps for network administrators.
