Network Security & Attack Techniques
Overview
Welcome to the Network Security & Attack Techniques module of the AppSec Atlas. This comprehensive guide covers the foundational principles of securing network infrastructure, understanding how attackers exploit protocol vulnerabilities, and implementing robust defenses at the network layer.
[!NOTE] This module is designed for both security analysts looking to understand attack vectors and network engineers aiming to harden their infrastructure.
Prerequisites
- Basic understanding of the OSI Model and TCP/IP stack.
- Familiarity with Linux command line.
- Basic Python knowledge for Scapy scripts.
Learning Objectives
- Understand the inherent vulnerabilities in foundational network protocols.
- Learn packet analysis and reconnaissance techniques using Wireshark and Scapy.
- Analyze Man-in-the-Middle (MitM) and DNS-based attacks.
- Deploy and configure network defense mechanisms like firewalls, IDS/IPS (Suricata), and VPNs (WireGuard).
- Grasp the concepts of network segmentation and Zero Trust architectures.
