CIS 337 Unit 7 Assignment Final Project Part IV Presentation to StakeholdersCoburne S. LeslieDr. Mohamed Ben Haj Frej, Ph.D.:MCSE, CCNACIS337: Networking in BusinessPost UniversityFinal Project Part IV Presentation to StakeholdersThis proposal is developed for a medium-sized organization that has plans on bothnational and international expansion, through the implementation of a Wide Area Network(WAN). I am requesting revenue to supplement the development of the parameters withinthis proposal. Once the proposal has been approved by the organization's executive boardmembers, which consists of the Chief Executive Officer (CEO). Chief Finance Officer(CFO) and Chief Information Officer (CIO), development will commence. This networkwill facilitate a better ease-of-access for clients, employees, and managers, thus alleviatingissues surrounding file sharing, communication constraints, and security concerns, whichwill in turn promote organizational growth and productivity.Part I: Planning the NetworkAreas of focus will consist of. internal and external networking components,quantity of users at each location, security protocols (in transit and at rest), WANarchitecture, data access and file sharing, remote access, and connectivity for local andinternational users.Stakeholders:The organization s stakeholders will consist of the Chief Executive Officer.Chief Finance Officer, and Chief Information Officer.Network Topology:In a WAN environment, the Hub and Spoke topology is the bestchoice to be used for connecting critical local and international networking sites together,where high redundancy and minimal latency are essential for optimal operation.Central Office (Hub):The central office or headquarters often serves as the hub. Thiscentra] location hosts critical network resources, including servers, data centers, and

services. It usually has a high-speed, reliable connection to the internet and extensivenetwork infrastructure.Branch Office or International Locations (Spokes): Thebranch offices or "RemoteLocations." are the spokes in this network. They are connected to the centra] office viawide area network (WAN) links, such as leased lines or W N connections.Projected Data Pathways once Network is Operational:Data originates from end-userdevices such as laptops, desktops, mobile devices, or loT sensors. After which, computerswithin a LAN will communicate with each other directly prior to sending the data out ofthe local network. The router will then direct die data packets to their destination,determining the best path based on routing tables and protocols through shielded networklines.The data will then pass through the firewalls which will restrict or permit trafficbased on the implemented protocols. Its primary function is to protect the network fromunauthorized access, threats, and vulnerabilities. Data destined for the cloud or externalservers must traverse the WAN to reach its destination. Connections will be established viadedicated ISP Telecom lines and VPNs.Once data reaches the WAN, it is sent over the public internet or dedicatedconnections to a cloud gateway, which is an entry point to the cloud provider's network.Lastly, data is then directed to the appropriate cloud servers edge routers to relay that datato another site location within the infrastructure.Interna]and ExternalComponents:Cisco SD-WAN Meraki Licensed MX95-SEC 5Year Plan. It provides strong security, flexibility, and scalability, making it suitable for bothnational and international deployments. It has the scalability to support up to 500 users.

Furthermore. "It has multi-layered security which provides the flexibility* to deploy theright security in the right place, either on-premises or cloud-delivered" (Rohyans et al.,2019)Load Balancer:F5 BIG-IP ADC 5200v offers a range of load balancing and trafficmanagement features, making it suitable for both national and international networkssupporting up to 5DD users for future sustainability for employees and customers.Network Monitoring Tool:Cisco Prime Infrastructure 1.1 Migration is a comprehensivenetwork management system that provides end-to-end visibility* and control over yournetwork It is suitable for both local and international networks and supports up to 500users.EdgeRouter: Arista Networks 7000 Series: Arista's 7000 Series edge routers are designedfor cloud and data center environments. They offer high performance and support foradvanced networking protocols, making them suitable for large-scale cloud deployments.VPN:Cisco Meraki AnyConnect Essentials supports site-to-site VPN connections, whichcan be used to securely connect multiple branch offices or remote locations to a centralnetwork. "The traffic is encrypted using an AES cipher.'" (Ajit. 2021) Additionally, itsupports up to 250 concurrent users.Firewalls:The Zscaler Advanced provides cloud-delivered security*, making it suitable fororganizations with a global presence. Quickly identify and intercept evasive and encryptedcyberthreats biding in traffic on nonstandard ports." (Firewall Zscaler. 2023)In Transit andxAT-Rest Network Security:Transport Layer Security (TLS)to encryptdata in transit over the network. This is essential for securing data during communication,such as web browsing, email, and application data transfer. HTTPS for secure data
