Tiivistelmä
The main objective of this thesis is to study the infrastructural alteration of a company network. The case company is a Finnish company Tapojärvi Oy. This thesis analyses the original network infrastructure, the requirements for the new one, the alteration, and finally it analyses the network infrastructure after the alteration. One objective is to study the information security of the network. Therefore, the thesis discusses the concept of information security and analyses the information security of Tapojärvi Oy’s network.
Among several reasons, the growing number of employees in the case company resulted in a need for a change as the firewall encountered a massive load and ran out of capacity. The growth required a solution that enables a proper management for both users and network resources for flexible yet secure network. For an effective end solution, this thesis research uses empirical data generated on the field. The empirical data is supported by theoretical data from literature reviews.
The alteration included virtualizing the firewall and adding most of the sites logically in the same network although they physically remain in different networks. The VPN solution was changed from PPTP and IPSEC to SSL and some hardware was replaced.
The alteration of the network infrastructure resulted in a more secure, flexible, and liable network infrastructure. Furthermore, it led to a more user-friendly solution for remote users. This in conclusion influenced the business in a positive way, as a secure and functioning network is a business critical component for the case company.
