These weaknesses emphasize the importance of **integrating security from the beginning** rather than treating it as an afterthought.  \n\nStudying these protocols helps in understanding:  \n- The **challenges of network security**  \n- The necessity of **various security measures**  \n\nThis lab provides hands-on experience with several **TCP/IP** protocols to illustrate real-world network infrastructure.  \n\n---\n\n## 🏆 Lab Objectives  \nIn this lab, students will conduct **multiple attacks on TCP**, covering the following topics:  \n\n✔️ **The TCP Protocol** – Understanding its structure and functionality  \n✔️ **TCP SYN Flood** – Exploring denial-of-service (DoS) techniques and **SYN cookies** as a defense mechanism  \n✔️ **TCP Reset** – Disrupting established connections by injecting forged TCP reset packets  \n✔️ **TCP Session** – Exploiting sequence number prediction to take over an active session  \n✔️ **Reverse Shell** – Gaining remote control over a target system using TCP-based exploits  \n\n\n---\n\n🚀 **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.**  \n\n\n![image](https://github.com/user-attachments/assets/fb4d3fd1-1a54-4cab-92ad-9c3808f54541)\n\n\n\n## 🛠️ Languages and Utilities Used  \n- **Python**  \n- **Ubuntu 20.04 VM**  \n\n---\n\n## 💻 Environments Used  \n- **Windows 10 (21H2)**  \n\n---\n\n## 🔍 Program Walk-through  \n\n## 🚀 Task 1: SYN Flooding \n🔹 **Task 1.1:** Launching the the network connection using **Python**  \n🔹 **Task 1.2:** Launching the connection using **C**  \n🔹 **Task 1.3:** Enabling the **SYN Cookie** countermeasure  \n\n## 🚀 Task 2: TCP RST connections on Telnet Connections  \n🔹 **Manual Execution**  \n🔹 **Network Automation(Terraform)**  \n\n## 🚀 Task 3: TCP Session \n🔹 **Manual Execution**  \n🔹 **Network Automation(Terraform)**  \n\n## 🚀 Task 4: Creating a Reverse Shell Using TCP Session \n\n---\n\n✅ **This lab provides hands-on experience in executing and mitigating critical TCP/IP, strengthening your understanding of network security measures.**  \n\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fpriyabug%2Ftcp-ip-protocol-analysis-implementation","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fpriyabug%2Ftcp-ip-protocol-analysis-implementation","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fpriyabug%2Ftcp-ip-protocol-analysis-implementation/lists"}
