Abstract

In recent years, mobile network communication became more secure. The reason is encapsulation with TLS protocol, that encrypts transmitted data. User security was increased, but on the other hand it limits network monitoring possibilities, because the data are encrypted. This thesis researches possibilities of monitoring mobile applications in network traffic using JA3 and JA3S fingerprints. The aim is to implement tools for automated creation of fingerprints database and consecutive detection.
