The thesis deals with the creation of a tool that can detect newly created network connections at the kernel level and in web browsers. It explains the theoretical foundations and methods of the network flow monitoring. It also describes how creating network connections works in the Linux and Microsoft Windows operating systems, with a special focus on sockets, and it offers options for monitoring network connections in web browsers, too. The creation of network connections is detected using BCC technology, where the system calls responsible for creating a new network connection are directly monitored. Monitoring of network traffic generated by web browsers is implemented through the browser extension webRequest. The main task of the tool is annotating this traffic by combining the information from the browser extension with the information about new network connections.
Creation of network drivers for the Windows family of operating systems
Krkoš, Radko ; Hošek, Jiří (referee) ; Růčka, Lukáš (advisor)
This thesis describes the approach in designing and implementing a driver marking network traffic for quality of service provision. In the beginning distinct technologies usable for the driver development are discussed and compared to each other while the most suiting candidate is chosen for driver development. Next the thesis discusses the design of the driver according to specification and depicts a list of more specific requirements affecting the driver design itself. The focus point in design is the least possible impact on network traffic performance and the running system itself. In addition to the driver an application programming interface usable from user mode is designed and so the system as a whole ensures the marking of network traffic entirely. In the end the created driver architecture is described and the application programming interface is described in terms of use.
