Faraday Cage: Practical examples

The Faraday cage, named after the English physicist Michael Faraday, was introduced in of the previous articles. It is a device designed to protect people or equipment from electric fields. It uses an enclosed metal structure that blocks the electric field and prevents it from affecting objects inside the cage. The Faraday cage is used in many areas of science, technology and everyday life. Some examples of applications will be given in the following paragraphs. Protection of electronics against electromagnetic radiation Nowadays, when data transmissions and sensitive electronics are increasingly vulnerable to electromagnetic fields, the Faraday cage is commonly used to protect electronic devices. For example, special rooms equipped with Faraday cages are used in laboratories and research facilities to protect electronics from interfering signals. These cages are often made of copper or aluminium mesh and are designed to prevent electromagnetic interference, which is particularly imp...

NFC and RFID Skimming: how to protect yourself from data theft at close range

NFC (Near Field Communication) and RFID (Radio-Frequency Identification) technologies have become an integral part of our daily lives. These technologies allow us to make contactless payments, access services or transfer data conveniently and quickly. However, with their growing popularity come new threats such as NFC and RFID skimming, methods that attackers use to steal data in your vicinity. What is NFC and RFID skimming? NFC skimming is a form of data theft in which an attacker uses NFC technology to steal information from your devices, such as credit cards or smartphones. NFC works over a very short distance, usually within a few centimetres, which allows attackers to stealthily approach close to you and capture data without your knowledge. How does NFC and RFID skimming work? Unlike other types of skimming, NFC/RFID skimming does not require extensive technical knowledge and the attacker can even make do with his mobile phone if it has an NFC/RFID reader. The reader can also ...

What is penetration testing and why is it important

Cybersecurity is a key issue for companies and individuals today. With the growing threats in the digital world, it is important to always stay one step ahead of potential attackers. One way to achieve this is by regularly conducting penetration testing. But what exactly is penetration testing and why is it so important? What is penetration testing? Penetration testing, often abbreviated as pentest, is a simulated cyber attack on a system, application or network to identify vulnerabilities that could be exploited by real attackers. The testing is conducted by cybersecurity experts who attempt to penetrate the system using the same methods that hackers might use. That's why these experts are also called ethical hackers. Their goal is not to cause harm, but to expose vulnerabilities before someone with malicious intent discovers them. Penetration testing can include different types of attacks such as: Network attacks: Testing for weaknesses in network infrastructure such as fi...

4 reasons to use a Faraday bag

Among the most common questions we answer is definitely the most basic question - what is the Faraday bag suitable for and what situations should it be used in? Not only on our e-shop, you will find a lot of information about Faraday bags being suitable for law enforcement officers who primarily need to ensure that essential data is not deleted when transporting devices of interest. However, this is not the only use, and the Faraday bag is also suitable for the average user who likes to protect their privacy. We have therefore decided to describe some situations in this article. We certainly don't need to remind you that nowadays electronic devices are an indispensable part of our every day and due to frequent interactions, we store very sensitive personal and professional information on them. This is, of course, very convenient, but only until our sensitive data is illegally obtained or altered. And that you have nothing to hide? You don't want anyone to be able to look through famil...

Faraday Cage

In today's technologically advanced world, we face many challenges regarding electromagnetic interference and the protection of sensitive electronic equipment. One of the most important and effective tools to protect against these problems is the Faraday cage. This article will focus on the principles, history and modern applications of the Faraday cage. What is a Faraday cage? A Faraday cage is a device designed to block the electromagnetic field. It is named after the British scientist Michael Faraday, who was introduced in our previous article. The cage is made up of a conductive material that surrounds a certain space and protects it from external electromagnetic fields. Its principle is based on the fact that electric charges redistribute across the surface of the conductor, creating an opposing field that cancels out external electromagnetic effects inside the cage. The history of the Faraday cage  Michael Faraday, the eminent 19th century physicist and chemist, discover...

Who was Michael Faraday?

Michael Faraday is one of the outstanding scientists of the 19th century, whose work fundamentally influenced the development of modern physics and chemistry. Although he had no formal education in the field, his enthusiasm, curiosity and determination led him to make discoveries that laid the foundation for many of the technologies we encounter every day. Early life and the path to science Faraday was born on 22 September 1791 in Newington Butts, an area that is nowadays a part of London. His family was poor and Faraday could not devote himself to education, as he had to work from the age of thirteen. He was apprenticed to a bookbinder with his employer and through his work he had access to many books which he read and studied with great interest. He was particularly fascinated by science, which led him to attend the lectures of the famous chemist Humphry Davy, with whom he later worked as an laboratory assistant. He also accompanied him on scientific trips around Europe, where he c...
