Despite their seemingly endless coverage (your mileage will definitely vary), cellular network security has proven to be surprisingly robust over the years. There have been security issues over the years to be sure, but the lion’s share of problems have come from the way that people use the network rather than the network itself being compromised.
These threats can come from all of the usual sources that you would try to protect from online, but there are some that are also uniquely tied to mobile devices. Today we’re going to be briefly covering some of the security functions that had been implemented over the years for cellular networks and some of the threats we still face on a day to day basis when it comes to mobile security.
There are a number of different communication technologies that most users are at least somewhat familiar with but are tied to particular ‘Generations’ of devices and their associated networks- GSM (Global System for Mobiles) and CDMA (Code Division Multiple Access) were commonplace during the 2G and 3G era, LTE (Long Term Evolution) for 4G, and 5G-NR for 5G networks that are still being rolled out.
