Training Overview
The "Firewall Bypass Techniques" training provides a comprehensive overview of the various methods used to bypass network security firewalls and the strategies to defend against these methods. The training begins with an introduction to basic firewall concepts and includes advanced evasion techniques such as source packet obfuscation, packet fragmentation, header manipulation, port hopping, tunneling, and non-standard protocols.
What you will learn
- How to use Nmap for source control, packet fragmentation, and header modification to evade detection.
- The concepts of port hopping and port forwarding to bypass firewall rules.
- How to tunnel traffic through allowed ports and protocols.
- The difference between traditional and next-generation firewalls.
Tools you will use
- Nmap
- Netcat
- hping3 (Conceptual)
Prerequisites
- A strong understanding of TCP/IP, networking protocols, and ports.
- Prior experience with Nmap and other network scanning tools.
Who this is for
- Network Security Engineers.
- Advanced Penetration Testers.
- Red Team operators.
