How to Choose The Best Expat VPN
Once you move out of a country to somewhere else, you lose access to all the location-locked content. For some countries that may not be a big issue, but if you move out of the US, for example, the content offered by every streaming service and many other platforms will change greatly. A virtual private network (VPN) can help you circumvent the issue entirely. As long as the virtual private network has servers in that particular country, you can access any location-based content. That’s part of the reason as to why VPNs became so popular – they allow you to access web services and content that otherwise would not be available to you.

5 Tips to Prevent Screen Hacking
Screen hacking is a new type of attack that injects fake touchpoints on a touchscreen by using electromagnetic interference EMI. A hacked screen can be used to perform any action on the device, including opening browsers, sending messages, or installing software. Hackers use dedicated devices to send signals to your touchscreen that mimic the same signal sent when the screen is being touched. Luckily, it’s currently impossible to do that from a long distance, so the person has to be within a few meters of you, making it easier to understand what’s going on.

Password Entropy: Definition and How to Calculate It
Password entropy is a key concept for creating a strong password. Expressed in bits of entropy, it gives us an objective measurement of how difficult it is to crack, guess, or brute-force attack passwords. We all know that strong passwords must be complex and include lots of special characters, numbers, lowercase, and uppercase letters. Understanding what password entropy is and how to calculate it helps create strong passwords you can remember but criminals struggle to crack.

NFC Security: Risks and How to Protect Yourself
NFC (Near-Field Communication) is a short-range wireless technology that allows devices to transmit information over short distances (usually, a few to a dozen centimeters). NFC signals are widely used for small, quick operations such as contactless payments and access control. It’s built upon the RFID technology and is intended to be more secure. However, NFC security isn’t foolproof either – there’s plenty of ways for various people to abuse the system. Since NFC signals are used for important operations (e.g., contactless payments), knowing how to avoid such situations is vital.

MAC Flooding: Effective Strategies to Combat Network Attacks
MAC flooding is a network attack that intends to overwhelm a switch (a device that directs data packets to specific MAC addresses), causing it to enter a fail-safe mode. A network switch, when overwhelmed, enters an “open” mode where all information is sent to every port to avoid taking down the network. Since all data is transmitted to every MAC address, the security of a network is compromised. Normally, a switch would only send data to specific ports and addresses. In the fail-safe mode, port security is compromised as all information is transmitted to every port.

IP Fragmentation Attack: Understanding the Threat and How to Prevent It
We’re all familiar with the pain of sudden internet connection problems, instability, and the constant website crashes. And while this could just be an innocent connection loss, it could also be a sign of an IP fragmentation attack. Although a lesser-known threat, it’s a type of cyber attack that exploits the way internet protocols handle data transmission to evade firewalls, disrupt services, and infiltrate networks undetected. If successful, a slowed internet would be the least of your worries – there would also be a risk of major application crashes, and worst still, malicious and unauthorized data breaches. That’s why it’s important to be informed and know how to protect your device properly.

How to Encrypt Internet Connection: A Comprehensive Guide
No one's forcing us to lock our front doors, but everyone does it anyway. Encryption plays a similar role in safeguarding your internet connection, except that many people still don't do it. The concept of encrypting internet traffic isn't so well-known. Simply put, encryption makes information unreadable by unauthorized third parties. Just as someone without a key can't access your locked house, no one without an encryption key can access your encrypted data. We're going to cover all the basics to start locking the cyber doors to your internet connection. With the right tools, sensitive data can be protected without much hassle.
