This project report details a comprehensive network security plan for First National University (FNU). It begins with an introduction to the project's scope, focusing on network redesign, security planning, and technology implementation. The report analyzes network traffic, proposes a new network design, and includes a trade-off model and IP addressing schema. A detailed network security plan is presented, outlining objectives, assumptions, and a thorough risk analysis. Security policies covering communication, network access, workstation use, antivirus measures, DMZ, and extranet access are defined. The project further addresses disaster recovery, business continuity, and access control strategies. Technology implementations are discussed, including DMZ configuration, test plans and results, Radius server setup, and IDS deployment. The report also covers switching and routing protocols, including IEEE 802.11 for RSTP, OSPF, and VLAN configuration. Finally, the project concludes with a summary of the FNU network, business and technical objectives, and a bibliography of cited sources.
