Design network infrastructure for business

Abstract

Nowaday, "Design Network Infrastructure for Business" is the most essential field to the development of an organization. Computer network is a set of computers connected. Computers on a network are called nodes which are linked via Ethernet cable or wirelessly through radio waves. Connected computers can share resources, like accessing to the Internet, printers, file servers and others. Therefore, network infrastructure is the indispensable factor of organization, companies or schools. In conclusion, the project "Design network infrastructure for business" is conducted to contribute to solving the problem of security, internal data safety, to increase the performance of the company. Network system is used for the management of internal data in a company. From that, we can maintain all units (computer’s users, servers, routers, switches, …) of organization. Moreover, it is hard for external malware to infiltrate agency's network system because of high security and privacy (Firewall, GPO, Antivirus software, …). For some reasons, only members (including administrators and users) in company can gain access to certain database. Basically, a network infrastructure includes 3 main parts: Network devices (routers, switches, …), Servers and Domain Controllers. About software, IT engineers can create these facilities from Window services without any cost. Howerver, there still are some services that we need to pay such as web hosting, SSL certificate, … In terms of hardware, it may cost a lot for Firewall Fortigate (can be used as Router), Switches (Layer 2 and Layer 3), Cable or Workstation Computers. In our project, we design a network infrastructure with fundamental components of network system. And we concentrate on servers and security of our system because it is the core of whole network. For more details, we totally focus on making a web application for our web server; designing mail server, DNS, domain controller and security for our system. To accomplish this project, our team needs to understand the structure of connection between hosts and function of each part in system. Beside, we need to investigate the security methods to protect our system from DoS/DDoS attack. Moreover, we have to do research on PHP language and Laravel framework to create a web app with backend and frontend.
