    CIS 337 Unit 7 Assignment Final Project Part IV Presentation to Stakeholders Coburne S. Leslie Dr. Mohamed Ben Haj Frej, Ph.D. : MCSE, CCNA CIS337: Networking in Business Post University Final Project Part IV Presentation to Stakeholders This proposal is developed for a medium-sized organization that has plans on both national and international expansion, through the implementation of a Wide Area Network (WAN). I am requesting revenue to supplement the development of the parameters within this proposal. Once the proposal has been approved by the organization's executive board members, which consists of the Chief Executive Officer (CEO). Chief Finance Officer (CFO) and Chief Information Officer (CIO), development will commence. This network will facilitate a better ease-of-access for clients, employees, and managers, thus alleviating issues surrounding file sharing, communication constraints, and security concerns, which will in turn promote organizational growth and productivity. Part I: Planning the Network Areas of focus will c onsist of. internal and external networking components, quantity of users at each location, security protocols (in transit and at rest), WAN architecture, data access and file sharing, remote access, and connectivity for local and international 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 best choice 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. This centra] location hosts critical network resources, including servers, data centers, and

    services. It usually has a high-speed, reliable connection to the internet and extensive network infrastructure. Branch Office or International Locations (Spokes): The branch offices or "Remote Locations." are the spokes in this network. They are connected to the centra] office via wide area network (WAN) links, such as leased lines or W N connections. Projected Data Pathways once Network is Operational: Data originates from end-user devices such as laptops, desktops, mobile devices, or loT sensors. After which, computers within a LAN will communicate with each other directly prior to sending the data out of the 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 network lines. The data will then pass through the firewalls which will restrict or permit traffic based on the implemented protocols. Its primary function is to protect the network from unauthorized access, threats, and vulnerabilities. Data destined for the cloud or external servers must traverse the WAN to reach its destination. Connections will be established via dedicated ISP Telecom lines and VPNs. Once data reaches the WAN, it is sent over the public internet or dedicated connections 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 data to another site location within the infrastructure. Interna] and External Components: Cisco SD-WAN Meraki Licensed MX95-SEC 5 Year Plan. It provides strong security, flexibility, and scalability, making it suitable for both national 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 the right 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 traffic management features, making it suitable for both national and international networks supporting up to 5DD users for future sustainability for employees and customers. Network Monitoring Tool: Cisco Prime Infrastructure 1.1 Migration is a comprehensive network management system that provides end-to-end visibility* and control over your network It is suitable for both local and international networks and supports up to 500 users. Edge Router: Arista Networks 7000 Series: Arista's 7000 Series edge routers are designed for cloud and data center environments. They offer high performance and support for advanced networking protocols, making them suitable for large-scale cloud deployments. VPN: Cisco Meraki AnyC onnect Essentials supports site-to-site VPN connections, which can be used to securely connect multiple branch offices or remote locations to a central network. "The traffic is encrypted using an AES cipher.'" (Ajit. 2021) Additionally, it supports up to 250 concurrent users. Firewalls: The Zscaler Advanced provides cloud-delivered security*, making it suitable for organizations with a global presence. Quickly identify and intercept evasive and encrypted cyberthreats biding in traffic on nonstandard ports." (Firewall Zscaler. 2023) In Transit andxAT-Rest Network Security: Transport Layer Security (TLS)to encrypt data 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
