Short Tutorial on Mission Critical Services in LTE and 5G

Over the years we have looked at the standards development, infrastructure development and even country specific mission critical solutions development in various blog posts. In this post we are sharing this short new tutorial by Mpirical on mission critical services in LTE and 5G. The video is embedded below:

Attack Surfaces for Different Generations of Mobile Technologies

At DEF CON 31 last year, Tracy Mosley, Vulnerability Researcher at Trenchant presented a talk titled "Nothin’ but a G Thang - The Evolution of Cellular Networks" (background of title). The abstract of the talk says:

In this talk we will walk through each step of cellular evolution, starting at 2G and ending at 5G. The never-ending attack and defend paradigm will be clearly laid out. In order to understand the attack surface, I’ll cover network topology and protocol. For each cellular generation, I will explain known vulnerabilities and some interesting attacks. In response to those vulnerabilities, mitigations for the subsequent cellular generation are put in place. But as we all know, new mitigations mean new opportunities for attackers to get creative. While I will explain most cellular-specific terminology, a familiarity with security concepts will help to better understand this talk. Basic foundations of communications systems, information theory or RF definitely make this talk more enjoyable, but are absolutely not necessary. It’s a dense topic that is highly applicable to those working on anything that touches the cellular network!
