Network Security - Implement L3 Routing Table & ACL in C/C++

🌟 Network Security - Implement L3 Routing Table & ACL in C/C++ 🌟

Course Headline: FireWall, Access Control Lists in C/C++, Bit Level Programming, Network Development/Distributed System/Embedded Systems etc.

Course Description:

As of 22 Sept 2022, this course is under active development, and we're excited to guide you through the complex world of networking with a focus on implementing essential data structures for network security. Our journey will delve into the intricacies of IPV4 Routing Tables and Access Control Lists (ACLs), which are critical components in any modern networking system, from embedded devices to large-scale distributed systems and cloud computing environments.

🚀 Key Takeaways:

• Understanding of Data Structures: We will construct a library called mtrie, a variant of Trie, which serves as the foundation for our implementation. Trie data structures are powerful tools in solving industry-specific problems.

• Real-world Application: By mimicking Cisco's ACL functionality, we aim to replicate the security and access control mechanisms that are fundamental in protecting network resources.

🔧 Hands-on Learning with Code Examples:

Our course will be heavily data structure and algorithm-centric, demonstrated through practical examples written in C/C++. While the focus is on these languages, you're encouraged to apply the concepts you learn in any language that suits your project needs.

Pre-requisite:

• Basic Networking Knowledge: A solid understanding of subnet masks and a basic networking background are essential for grasping the course material.
• Intermediate Developer Level: This course is tailored for intermediate to advanced developers. If you're new to programming, we recommend starting with more foundational topics before diving into this course.
• Bit-Level Programming Skills: Due to the complexity level of this course, a strong proficiency in bit-level operations is required.

End Product:

Upon completion, you'll have fully functional Routing Table and ACL libraries ready for integration into your projects or to showcase on your resume as significant technical milestones.
