Secure Network Design

An IT network is a group of computers, servers, and other devices that are connected together to share resources and communicate with each other. IT or Information Technology deals with the systems mainly computers and telecommunication for performing various operations like for giving input, for storing, recovering, transmitting, manipulating and protecting data or information so that data can be exchanged among different organizations. A computer network comprises two or more computers that are connected—either by cables (wired) or WiFi (wireless)—with the purpose of transmitting, exchanging, or sharing data and resources.

The number of devices that a small business should have on their network depends on the size of the business and the number of employees. If the total number of devices connected to your network is 20 or more, you should invest in commercial or business-grade Wi-Fi equipment because consumer-grade or home routers can handle only a limited number of devices.

When building a small business network, you will need one or more routers. In addition to connecting multiple networks together, the router also allows networked devices and multiple users to access the Internet. When building a small office network, the two most essential pieces of equipment you will need are switches and routers. These networks may be in a single location or across multiple locations.

Network Design Best Practices:

• Consider business-grade switches and routers: Consumer or home-networking products will not deliver the reliable communications your small business needs or keep pace as your business grows.
• Invest in a network designed to grow over time: Your small business may start with just a few employees, but it's important to plan for growth. Invest in a network that can grow with your business.
• Use network segmentation: Network segmentation is the process of dividing a network into smaller, more manageable sections. This can help to improve security and performance.
• Use firewalls: Firewalls are an essential part of any network security strategy. They help to protect your network from unauthorized access and can help to prevent data breaches.
• Use VPNs: VPNs are a great way to provide secure remote access to your network. They can help to protect your data from unauthorized access by encrypting your data.
• Use cloud-based services: Cloud-based services can help to reduce the cost of IT infrastructure and can provide greater flexibility and scalability.

Steps for Designing a Computer Network:

1. Gather Requirements: Determine the needs of your business and the number of devices that will be connected to the network.
2. Size Your Network: Determine the size of your network and the number of devices that will be connected to it.
3. Study Your Office Floor Plan: Study your office floor plan to determine the best location for your network equipment.
4. Choose An Internet Service Provider (ISP): Choose an ISP that can provide the bandwidth and speed that your business needs.
5. Create A Network Design Document: Create a network design document that outlines the design of your network.
6. The Network Design: Design your network based on your requirements and the size of your business.
7. Follow Network Design Best Practices: Follow network design best practices to ensure that your network is secure and reliable.
