Computer Networks 12: Analysis of Network Security Concepts and Models

This assignment solution for Computer Networks 12 explores various aspects of network security. It begins with an analysis of the OSI model, its advantages, and disadvantages, along with the use of domain controllers. The assignment then delves into bandwidth considerations when switching from access points to switches, estimating effective bandwidths in both scenarios. It further examines network collisions, comparing hubs and switches, and their impact on collision rates. The solution also addresses the suitability of UTP cables for network backbones, highlighting their limitations. Furthermore, it discusses the benefits of transitioning to IPv6 and the technologies enabling coexistence with IPv4. The assignment includes an analysis of switching tables and malware, specifically Trojan horses, and provides defensive measures against them. Finally, it explores cloud computing services, recommending Software as a Service, and solutions for centralized data storage, including Storage Area Networks (SANs) and Network Attached Storage (NAS).
