Abstract

The project focuses on the research of new methods of effective protection against cyber threats that misuse secured communication for compromise attacks such as servers and computers in the environment of high-speed networks. Machine learning methods suitable for determining the characteristics of the encrypted network flows and associated risks only from available metadata will be investigated. The system will be implemented using a hardware-accelerated traffic monitor and a software prototype for high-speed detection of security incidents and their reporting to the SIEM tool. Further, the incident analysis module in the form of a plug-in to the QRadar system will be developed. Additionally, the project outcomes will also include reference data sets of network traffic and a system for their collection and annotation.
