And the company that usually holds that map of your habits? Your mobile carrier. AT&T, T‑Mobile, Verizon — the big three — collect and share more data than most people realize. Here’s what they gather, why it matters, and what you can do about it. What they collect (spoiler: it’s a lot) Carriers log the usual identification details: your name, home address, email, date of birth — the information you provide when you sign up.

Whether checking emails, shopping online or backing up your files, servers make all this happen behind the scenes, ensuring a productive online experience. There are many different types of servers, each with a specific role. Let’s break it down in a simple way! Now, let’s start with the Web Server. Think of this as the front desk clerk of the internet, always ensuring your safety. When you visit a website, a web server delivers the web pages to your browser. It handles HTTP requests, the standard for browsers to communicate with web servers. It also supports various programming languages, like PHP or Node.js, to ensure websites work seamlessly. And security? That’s covered, too—most web servers use SSL certificates to ensure the data exchanged between your browser and the website is encrypted and secure. Next, we have the Email Server....

Photographer: Frederik Lipfert | Source: Unsplash A recent CISA pdf discusses the potential threats to 5G network slicing! This information was created by the National Security Agency and The Cybersecurity and Infrastructure Security Agency to provide guidance and recommended practices for industry stakeholders. Here are three questions and answers from the pdf to help inform you about 5G network slicing. What is network slicing, and why is it important for 5G networks? Network slicing is "an end-to-end logical network that provides specific network capabilities and characteristics to fit a user's needs." It allows for creating multiple virtual networks that run on a single physical network, with each network slice tailored to meet the specific needs of different users or applications. This is important for 5G networks because it enables the network to support a wide range of use cases with varying requirements for bandwidth, latency, and other network characteristics. B...
