Mobile devices have become an extension of ourselves, holding a wealth of sensitive information. As technology advances, securing these devices, especially in enterprise settings becomes increasingly vital. Mobile devices have unique characteristics compared to desktops, making their security a bit more challenging. In this article, we will explore various communication methods as well as the security concerns associated with enterprise mobile security.
Mobile devices use electromagnetic waves (zero and one) for communication with each other, but they lack the capability to transfer data over long distances independently. They rely on different methods such as a cellular network (5G is the fifth generation of cellular wireless standards providing capabilities beyond 4G), Bluetooth, Wi-Fi, near-field communications, and so on. Let’s look into these methods in-depth and the security concerns they present.
Cellular networks
Cellular networks, also known as mobile networks, are the primary mode of communication connecting end nodes through service provider networks. Each phone communicates with the service provider by radio waves through a local antenna at a cellular base station or cell site. These cellular networks consist of several components.
Cellular layout: Mobile networks are divided into different geographical areas known as cells. These cells are further divided into hexagonal cells — an antenna covers a cell with certain frequencies. Each cell has a transceiver, a mobile tower that wirelessly connects to mobile devices.
