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.

Helgrind: Detecting Synchronisation Issues in Multithreaded Programs
Let's explore how Helgrind can be used to detect and debug multithreading issues with the help of a multithreaded C program.
The Perfect Process of Booting a PC
Booting a PC seems as simple as eating a cake. But are you aware of all that goes on behind-the-scenes to bake a delicious cake or seamlessly boot a PC?
Exploring eBPF and its Integration with Kubernetes
eBPF, a game-changing technology that extends the capabilities of the Linux kernel, offers significant advantages for Kubernetes networking. It also greatly improves Kubernetes observability by capturing detailed telemetry data directly from the kernel. Read on to find out how its integration with Kubernetes has immense benefits.
Deploying Generative AI LLMs on Docker
Built on massive datasets, large language models or LLMS are closely associated with generative Al. Integrating these models with Docker has quite a few advantages.
Containerisation: The Cornerstone of Multi-Cloud and Hybrid Cloud Success
Open source containerisation software provides the flexibility, cost-effectiveness, and community support needed to build and manage complex multi-cloud and hybrid cloud environments. By leveraging this software, businesses can unlock the full potential of multicloud and hybrid cloud architectures while minimising vendor lock-in risks.
From Virtual Machines to Docker Containers: The Evolution of Software Development
Containerisation and Kubernetes have eased software development, making it faster and better. Let's see where these are headed, looking at trends that are making life easier for developers.
India's Leap in Supercomputing: Innovating for Tomorrow
As India strides towards self-sufficiency in supercomputing, embracing this evolution isn't just an option-it is pivotal for global competitiveness and technological leadership.
SageMath: A Quick Introduction to Cybersecurity
In the previous articles in this SageMath series, we delved into graph theory and explored its applications using SageMath. In this seventh article in the series, it is time to shift our focus to another crucial subfield of computer science: cybersecurity and cryptography.
Efficient Prompt Engineering: Getting the Right Answers
OpenAl's GPT-3 and GPT-4 are powerful tools that can generate human-like text, answer questions, and provide insights. However, the quality of these outputs depends heavily on how you frame the input, or prompt. Efficient prompt engineering ensures you get the right answers by designing inputs that guide the AI towards relevant, clear, and useful responses. Let's find out how to craft effective prompts with examples.
Analysing Linus Torvald's Critique of Docker
This article looks at Docker's security flaws, particularly its shared-kernel model, and contrasts it with traditional VMs for better isolation. It discusses Linus Torvalds' concerns, explores mitigation techniques, and proposes a roadmap for building a more secure containerisation platform using hardware-assisted virtualisation, true isolation, and a robust orchestration layer.
