Design a network, network security, and WAN connectivity.
This document presents the layout of an organization with 100 computers in three different places in the organization. This design’s goal is to make communication efficient, make data sharing flow with no hitches, and also have effective security for every user in the organization. The companies, equipment, and software that are being used are described, information about the network diagrams is included, security measures are discussed, and the WAN connection is described.
The Equipment and Software used are described Below
To establish a dependable and secure network, the following equipment and software will be implemented:
1. Routers: Cisco ISR 4000 Series routers are going to handle access to external connections and internal networks.
2. Switches: Cisco Catalyst 2960-X Series switches will interconnect the computers within each of these buildings for efficient high-speed data transmission and management. (SDWAN et al. 2018).
3. Computers: Dell Optiplex 7080 desktop computers will be made available for each of the users to meet the day-to-day tasks and activities.
4. Servers: The related server functionalities will be handled by Dell PowerEdge R740 servers, such as common file, application, and control servers.
5. Firewalls: they will offer defense against these threats and unauthorized access, the company will deploy Fortinet FortiGate 60E firewalls.
6. Antivirus Software: the organization will utilize the Symantec Endpoint Protection. It will act as the antivirus and tackle the matter of malware and viruses on computers and servers.
7. Network Management Tools: Due to its great features and effectiveness, SolarWinds Network Performance Monitor shall be employed to monitor performance and detect problems with the network’s function.
8. Operating Systems: The company will install Windows 10 on all the computers, while all servers will be run on Windows Server 2019 to ensure stability and security of the environment.
The components featured above were selected based on reliability, performance, and compatibility, which makes them suitable for the creation of a harmonized network.
Location-Specific Details
Location One
Location One here comprises two buildings, each with 25 computers.
• One Cisco Integrated Services Routers Generation 4000 Series router.
• Exactly one Cisco Catalyst 2960-X Series switch per building.
• 25 PCs per building, model Dell OptiPlex 7080, desktop.
• One computer – Dell PowerEdge R740.
• One Fortinet FortiGate 60E Firewall.
Location Two
Location Two consists of one building with 15 computers.
• One Cisco Integrated Services Routers Generation 4000 Series.
• retired one Cisco Catalyst 2960-X Series switch.
• 15 Dell OptiPlex 7080 ‘s Desktop.
• One Hardware Dell PowerEdge R740 server.
• One Fortinet FortiGate 60E firewall with 12 Ports.

Location Three
Location Three comprises one building, whereby there are 35 computers in that building.
• One Cisco Integrated Services Routers Generation 4000 Series router.
• Two Cisco Catalyst 2960-X Series supporting switches.
• 35 Dell OptiPlex 7080 desktop computers. (Wang et al., 2020).
• One is the Dell PowerEdge R740 server.
• The hardware used in the experiment was One Fortinet FortiGate 60E firewall.

Explanation of Security Procedures
To ensure the security of the network, the following measures will be applied:
1. Firewalls: The Fortinet FortiGate 60E firewalls will be installed at all those places to protect against the outside world and intruders.
2. Antivirus Software: The program to prevent the spread of malware or viral attacks on the devices will be installed in Symantec Endpoint Protection.
3. Encryption: To avoid a breach of the sensitive data stored in the system, physical data will be secured by encrypting it during transit as well as when it is to be stored.
4. Access Control: Security measures that check the level of user rights with what is needed in their areas of operation will be implemented.
5. Regular Updates: Every software and hardware must be kept up to date on the current version for security purposes against well-known exploits and risks.
6. Monitoring: SolarWinds Network Performance Monitor will be used for real-time monitoring to detect any possible threats so that they can be solved as soon as possible.
Explanation of WAN Connection
The WAN connection will simply be made through the dedicated leased lines between the two locations. The setup will feature:
1. Technology: MPLS is an efficient connectivity method that ensures high speed and reliability.
2. Topology: A design in which Location One is the main node, while the two other Locations are branches.
3. Bandwidth: Proper use of bandwidth that is timely and capable of satisfying the requirements of users as well as applications while transferring data. (Radosavovic et al. 2020).
4. Backup Connection: VPN over broadband is a redundancy technology rather than a primary solution, as the installation of a failover link guarantees continuous communication in cases when the primary link becomes unavailable.
5. Quality of Service (QoS): Proper ranking and prioritization of vital applications, including VoIP and video conferencing, should always work fine.
In this setup, there is continual sharing of information and knowledge, which will help the organization operate effectively in all its affiliate stations.
