While less common today due to better configurations, source routing allows the sender to specify the path a packet takes, potentially bypassing a firewall’s filtering point.
For a beginner, this is daunting. It is one thing to run a script; it is another to manually craft a fragmented packet sequence using tools like hping3 or Scapy . The learning curve is steep and discouraging for those without a strong networking background. ethical hacking: evading ids, firewalls, and honeypots
To evade a firewall, you cannot just rely on a tool; you must understand how TCP/IP works. The study of this topic forces you to learn about packet structure, fragmentation, and protocol headers. While less common today due to better configurations,
Deepens protocol knowledge; essential for Red Teaming; fascinating "hacker logic." Cons: Technical barrier to entry; techniques become outdated quickly; complex tooling. The learning curve is steep and discouraging for
