The vulnerabilities in the TCP/IP protocols represent a unique class of protocol design and implementation flaws. These weaknesses emphasize the importance of integrating security from the beginning rather than treating it as an afterthought.
Studying these vulnerabilities helps in understanding:
- The challenges of network security
- The necessity of various security measures
This lab provides hands-on experience with several TCP-based attacks to illustrate real-world network security risks.
In this lab, students will conduct multiple attacks on TCP, covering the following topics:
✔️ The TCP Protocol – Understanding its structure and functionality
✔️ TCP SYN Flood Attack – Exploring denial-of-service (DoS) techniques and SYN cookies as a defense mechanism
✔️ TCP Reset Attack – Disrupting established connections by injecting forged TCP reset packets
✔️ TCP Session Hijacking Attack – Exploiting sequence number prediction to take over an active session
✔️ Reverse Shell – Gaining remote control over a target system using TCP-based exploits
🔹 Bonus: A special type of TCP attack, the Mitnick attack, is covered in a separate lab.
🚀 By completing this lab, students will gain critical insights into TCP/IP security flaws and the importance of implementing robust security measures in network protocols.
