Virtualized security is a modern way to protect digital spaces mostly found online instead of on physical machines. This type of security is made for systems in data centers and cloud setups, where things like applications, servers, and networks exist virtually. It uses special security tools that work well in these virtual environments. These tools…
Clickjacking is a malicious trick where someone is fooled into clicking on something that isn’t what it seems. This could let hackers see private information or even take over their computers. Usually, this trick involves placing an invisible layer over a webpage that looks secure. The person thinks they’re clicking on the real webpage, but…
Differential privacy is a modern way to keep data secure that lets organizations learn very important things from datasets without giving away personal details. It works by adding a bit of random noise to the data. This means the results of any data analysis are pretty much the same, whether or not someone’s personal information…
In today’s world, our home internet connections are more important than ever because they keep us connected to everything online. However, as we depend more on these networks, the risks to them also increase. One major risk is the “zombie attack.” In this attack, hackers take control of devices and use them for harmful purposes,…
Cryptojacking is a hidden type of cyber attack where hackers use your computer’s power to mine cryptocurrency without your permission. This can slow down your devices and might also lead to losing money or having your private information stolen. As more people become interested in cryptocurrencies, these attacks are becoming more common. However, you can…
Homomorphic encryption is the highest level of cybersecurity, which will make it possible to perform some computations on encrypted data, bringing out an outcome in encrypted form. This, when decrypted, is equal to operations made over the plaintext. That is, the data can be securely processed without ever needing to be exposed in its readable…
Side-channel attacks are security exploits that subtly leak sensitive information from a system under various types of indirect data analysis. This might be in the way of power consumption, electromagnetic leaks, or even how long it takes for certain cryptographic operations to execute, as opposed to a direct breach into the software or code. They…
In today’s world, keeping our personal information private is very important for you. With more threats online and information being valuable, protecting things like our medical records or financial details is crucial. Privacy Enhancing Computation (PEC) is a new way to keep information confidential even while it’s being used. This is like having a special…
Air gapping is one of those security measures whereby one ensures that a physical computer or network is separated from unsecured networks, of which some may be examples like the internet and local networks. It is a very extreme but at the same time useful measure of defending against cyber threats. That is to say,…
Data exfiltration in cyber security is when someone illegally takes data from a computer or another device. It happens when sensitive, protected, or private information is copied, moved, or taken from a system without permission, often using harmful methods. This can happen in different ways, such as someone physically accessing a computer, remotely using malware,…
