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.

Owned by Amazon since 2018, Ring is one of the most popular manufacturers of smart home security devices. Ring doorbells, IP surveillance cameras, and home alarm systems connect to one wireless network that can be controlled from your phone.

As convenient as they are, Ring devices can become a home network security vulnerability instead of a security guarantee. Ring has done a lot to improve the security of its products, such as implementing end-to-end encryption. Still, you are the one in charge of your home and your home network security.

Can Ring cameras be hacked even if you take all the necessary precautions? We'll dive into the details and outline the steps you must take to protect your ring devices.

Most of us are already immune to the "traditional" phishing attacks via email. The vast majority of them are caught by the algorithms and go straight into the spam folder. Scammers do not rest and instead have switched their focus to social media users.

Impersonating companies and using your profile against you, scammers try to lure your personal information for their benefit in what's called an angler phishing attack. We'll discuss all you need to know to be safe from them.

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.

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 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.
