A network is simply a group of devices that are connected so they can communicate and share information. Think of it like a group chat for your devices. Your phone, laptop, smart TV, printer, and game console can all be connected to the same network. This allows them to send information back and forth without needing to be physically plugged into each other. A Real-World Example Imagine you're at home. Your phone is connected to your Wi-Fi. Your laptop is connected to the sam

Short answer: Yes, your employer can see a surprising amount of information when you connect to their Wi-Fi network. They can typically identify which device is connected, the device name, its assigned IP address, MAC address (a unique hardware identifier), which websites you're visiting, when you connected, how long you stayed connected, and approximately how much data you transferred. However, that doesn't mean they can see everything you're doing online. Most websites toda

Every device that connects to a network has something called a MAC address (Media Access Control address). Think of it as your device's hardware ID. A MAC address helps devices on the same local network recognize each other. For example, when your laptop connects to your home Wi-Fi, your router uses its MAC address to tell it apart from your phone, smart TV, or game console. Unlike an IP address, which can change depending on the network you're using, a MAC address is usually

If you've ever tried uploading a large video, backing up files to the cloud, or sending photos to someone online, you've probably noticed that it often takes much longer than downloading something of the same size. At first glance, this can seem confusing. If your internet is capable of downloading at hundreds of megabits per second, shouldn't uploading be just as fast? Not necessarily. In most cases, slower upload speeds are completely normal. Home internet connections are o

Firejail, the Linux sandboxing security software, may not be for everyone. Although Firejail is lightweight, powerful, and capable of improving application isolation, many users may find it difficult to learn or frustrating to configure compared to modern security applications with polished graphical interfaces. For experienced Linux users, this may not be a major issue. However, for beginners or users who simply want straightforward controls and clean usability, Firejail can

A NAS, short for Network Attached Storage, is a storage device connected to a network that allows multiple devices to store and access files from one central location. In simple terms, a NAS acts like a shared storage system for your home or business network. Instead of files being stored only on one computer, they can be accessed by other authorized devices connected to the same network. NAS devices are commonly used for: Extra storage File sharing Backups Media servers Busi

A HDD, also called a Hard Disk Drive, is a storage device inside a computer that stores your files, games, programs, photos, videos, and operating system. In simple terms, it is where your computer stores almost everything. Although SSDs have become more common in modern systems, HDDs are still widely used because they offer large amounts of storage at a lower cost. Many desktops, servers, external drives, and backup systems still rely on HDDs today. Unlike SSDs that use flas

An SSD, also called a Solid State Drive, is the storage device inside a computer that holds your files, games, programs, photos, videos, and operating system. In simple terms, it is where your computer stores almost everything. Most modern computers use SSDs because they are much faster than older hard drives (HDDs). A computer with an SSD can boot up quicker, open applications faster, and feel far more responsive during everyday use. Unlike older HDDs that use spinning mecha

Sandboxing is a security method used to isolate applications, files, or code from the rest of a system. It creates a restricted environment where software can run without being given full access to the operating system. The purpose of sandboxing is to reduce damage if an application is malicious, vulnerable, or unstable. For example, if malware runs inside a sandbox, the sandbox may prevent it from accessing personal files, modifying the system, or interacting with other appl

Firejail is a Linux sandboxing application used to isolate programs from the rest of your system. It works by restricting what applications can access using built-in Linux security features such as namespaces and seccomp filters. In simple terms, Firejail creates a controlled environment around an application. If that application crashes, behaves maliciously, or becomes compromised, Firejail helps limit how much of your system it can interact with. Firejail is commonly used a

Firetools is the graphical user interface (GUI) for Firejail. While Firejail itself is commonly used through the Linux terminal, Firetools provides a simpler visual way to manage and launch sandboxed applications. Instead of remembering terminal commands every time you want to sandbox an application, Firetools allows you to interact with Firejail through a desktop interface. This makes sandboxing easier for both beginners and experienced Linux users who want a faster workflow

To install Firetools, you first need to be using a Linux-based operating system. From your desktop, open the Terminal application. Inside the terminal, enter the following command: sudo apt install firejail firetools This installs both: Firejail — the sandboxing engine Firetools — the graphical interface for Firejail Press Enter after typing the command. If prompted, enter your system password. Keep in mind that Linux terminals usually do not display password characters while

The internet is no longer limited to phones, laptops, and gaming PCs running hot enough to cook ramen. Everyday objects are now connected too. Smart TVs, thermostats, refrigerators, doorbells, light bulbs, security cameras, watches, and even coffee makers can all connect to the internet. This massive network of connected devices is known as the Internet of Things, commonly shortened to IoT. At its core, IoT refers to physical devices that collect, send, and sometimes act on d

The internet is not free. You are the product being sold. When you visit websites or use social media, it often costs you nothing upfront. No subscription. No payment. Just access. So how does that make you the product? Your interests, browsing history, and inferred personal data such as age, gender, and behavior can be collected and used to target you with ads. Not just on one website, but across the entire internet. Most people see ads and think, “These are annoying, I just

Ads are everywhere. Simply visiting a website to get information usually results in ads being shoved in your face. My site used to be the same way. People expect ads now and just tolerate the annoyance, but for me, it never sat right. Reason One: Irony I found having ads on my website to be ironic. An entire category of focus of CyberCorks is cybersecurity, teaching users how to stay safe and protect their data. At the same time, running ads from companies like Google, which

I recently received an email claiming my website was about to be suspended. The message claimed to be from Wix, my website host, and used a strong sense of urgency to try and get my attention. Naturally, I took a closer look. And honestly… it was pretty funny. Phishing email claiming to be from WIX We can start from top to bottom of the email. You can see its a "Compliance Notice" Looking at the sender, it comes from wixreportsystem.help@gmail.com Yes really, sent from a

A cyberdeck is a custom-built portable computer, usually designed with a rugged or cyberpunk-inspired look, often running Linux and built from modular or reused components. Instead of buying a finished device, you build it yourself using parts like: Single-board computers (Raspberry Pi, etc.) Small displays or repurposed laptop screens External keyboards Batteries and custom enclosures Spare parts It’s part computer, part DIY project, and part aesthetic statement.
