Methods to protect and encrypt data on the Internet

The popularity of digital technologies led to a situation when a great portion of business processes and even personal life moved to the virtual world. In this situation the means to provide for security and protection of data on personal computers and mobile devices became highly important and include: VPN, antiviruses, firewalls, PGP-encryption. The Internet became a trusted intermediary in work and companionship, but it can also be a source of trouble if you do not pay enough attention to security.

Traffic encryption is the easiest and most reliable way to ensure security of your data. There is no sense to intercept it as decoding such data requires the key. And this is where the difficulties of the hacker start: this task requires the facilities only available at the military or government level.

Advantages of working over HTTPS protocol

HTTPS protocol uses a secure connection - all sent and received traffic is encoded; the most commonly used method is asymmetric encryption. This means that the hacker will face the problem of breaching two keys, one of which is held by the sender and the other is transmitted by encapsulation method along with the network packets. When using the symmetric method for data encryption, there are ways to get the key rather quickly bruteforcing the combinations.

Keys are exchanged via the same channel transmitting the protected traffic in their open form. It is believed that there is no need to encrypt it, since the security is provided by SSL-certificate viewed and accepted by the user. And this is exactly the biggest and most serious vulnerability of HTTPS.

Any intermediate server in the traffic’s path is a direct threat to its security, as the users often react automatically when notified about the need to accept SSL-certificate. As a result computer or mobile device of the hacker will receive all outgoing traffic, decrypt it, save and forward it to its destination. Accordingly, HTTPS cannot be considered to be completely safe, because the human factor plays a major role when using it.

Using SSH tunneling

When using SSH, the server and the client exchange keys at the beginning of the session. The connection is protected in a way that when the hacker attempts to intercept the traffic, he will be denied the connection due to their mismatch. However, there are software solutions able to intercept all traffic passing through a proxy server, and data encryption will not help in this case.

SSH tunneling is one of the most reliable ways to provide for data protection, but its use requires a trusted server to run a properly configured SSH daemon.

Advantages of OpenVPN

VPN is a one hundred percent confidential and secure way to encrypt and transmit data within both the local network and the Internet. VPN technology combines everything necessary to ensure maximum protection when working with open channels.

Virtual Private Network (VPN) is a set of measures focused on encryption and secure transmission of any data on the Internet. It is based on the use of the most up-to-date and attack-resistant cryptographic algorithms. And the level of trust to the network transmitting the data makes no difference. The use of VPN connection often does not even require installing additional programs - mobile devices (Android and iOS) already have the necessary settings.

OpenVPN is a tunnel that lets you run safely on your computer or mobile devices email clients, messengers and other Internet applications without the need for additional configuration. Reliable technology of traffic encryption ensures complete confidentiality and anonymity, and, if necessary, one can engage an additional level of protection to encrypt the address sending the packages.

SecureVPN company offers different packages to provide for different levels of data security in accordance with the client’s needs. OpenVPN connection will provide the protection for any type of connection – within the local network, when using your laptop or mobile device in open public Wi-Fi networks, and so on. And you may rest assured that even if the data gets intercepted, no one will be able to decrypt it. OpenVPN on your computer or mobile device will neither affect the performance, nor interfere with proper operation of other programs. It is so easy to use it that you will be able to independently make all necessary changes to the configuration without the help of professionals.

An additional advantage of this technology is the ability to hide your IP-address and work not only with the highest level of protection, but also anonymously and easily access many resources blocked by your ISP or system administrator.
