Abstract

The thesis deals with the possibilities of protecting the computer network of a small enterprise. At the beginning, different types of cyberattacks are described, then how these attacks take place and what damage they can do within two views. The first view deals with data leaks from inside the network, while the second view shows the dangers from the outside. The practical part of this thesis focuses on the design of computer network protection, where firstly the assets of the enterprise were identified with respect to the computer network. Next, a risk analysis was performed using the extended RIPRAN method to determine the magnitude of risk of the most vulnerable points of the computer network In this part, antivirus software, its purchase and comparison between its competitors in the cyber security market were considered. The final part of the thesis proposes a security solution for the computer network according to the given budget, including the calculation of capital costs to eliminate the impact of the identified threats.
