Detection of IMSI traps in cellular communication networks using an algorithmic approach

Khramtsov Ilya Alexandrovich

Due to the low level of protection of mobile networks from man-in-the-middle attacks, where they are used from false base stations of the mobile network, protecting user privacy raises an urgent issue in providing protection against this type of threat. The material of this article discusses a method that uses the identification and detection of IMSL traps based on the infrastructure of the GSM network. The main advantage of using this method is that it will protect all users from the general coverage of the operator's network while saving users money and resources by not having to purchase additional equipment.
