VPN Basic Concepts and Classification

The term VPN (Eng. “Virtual Private Network”) refers to a group of technologies that provide a network connection, or the so-called logical network, functioning on top of some other network, usually the Internet.

Although data is transferred to a VPN over networks with a low level of trust, thanks to the use of cryptography, the level of trust in a VPN can be arbitrarily high. Among the cryptography tools used are encryption, means to protect against changes in transmitted messages, public key infrastructure and authentication. Depending on the final destination, the VPN implements three types of connections: network-to-network, node-to-network and node-to-node.

Overview of modern antiviruses

Of all the threats to the security of user information, viruses stand apart. These small malicious programs, if not handled carefully, can steal or destroy any data. But it turns out to be easiest to defend against them. The Internet is teeming with dozens of different antivirus programs that offer us a quick and easy solution to the problem.

File encryption

Encryption is the most common and essentially the simplest way to protect any information. After all, it seems that it could be simpler to take the text, take some algorithm known to you and your friends and use the algorithm to make gibberish from the text that no one else can parse from you and your friends. Simple and pretty angry. To date, the solution remains the most reasonable.

However, many may argue, “then what is the effectiveness and complexity of encryption?” But it is in the selection of the algorithm. At the moment, there are a huge number of encryption systems and ciphers. And each of them is unusually effective and complex to a certain extent. However, they are all classified into two main categories: symmetric and asymmetric ciphers. Further we will focus on them. And already examining an example, we will show what data encryption is.
