CST 311 Week 8

 WAN-dering Off After The Final Ping

As we conclude the final week of CST 311 Computer Networks, it's a great time to look back on all the material we've covered. Over the past weeks, we've explored how networks operate, focusing on both foundational concepts and practical implementations of current protocols. We've learned about network layers, IP addressing, TCP/UDP, routing algorithms, congestion control, and many other topics, which has helped us understand the complexities of modern computer networking.

In this last week, we focused on network security. We covered firewalls, intrusion detection systems (IDS), and various encryption methods that keep communication secure. One of the key takeaways was understanding how firewalls act as crucial gatekeepers, managing what enters and leaves the network. We also looked into how IDS can detect malicious activity, providing a proactive defense against potential threats.

Beyond the technical details, CST 311 has emphasized the importance of seeing computer networks as dynamic systems made up of many interconnected parts, each playing a vital role in ensuring smooth communication. Concepts like routing algorithms and TCP congestion control were challenging at times, but using packet analysis to see them in action made the effort worthwhile. It was also insightful to study the roles of different networking devices, such as routers, firewalls, and switches, and how they work together to create secure, efficient, and reliable communication.

This course has been incredibly insightful, showing how these concepts directly apply to real-world situations. As I get ready to work on my capstone project, I feel more confident in my ability to bring my ideas to life. CST 311 has been a crucial part of my academic and professional growth, giving me the skills I need for success in my capstone and in my future career. I'm excited to use to use the things I have learned here.
