Finding VPN

beste internet securityWhen there is a VPN connection , the data is usually transferred between two or more computers on the Internet via a secure tunnel. The computers can access each other – as if they were in a local network.

Previously , virtual private systems were primarily utilized by companies, for example, to safely network departments or even to provide field staff with access to the corporate network. Today, VPN can be a significant service in the buyer sector, which is usually primarily used to protect against attacks in public WLAN networks .

And since the VPN connection will surely not become less important in times of increasing cyber threats , we’ve summarized the most important factual statements about the Virtual Private Network .

Virtual Private Networks: Benefits for Personal privacy & IT Security

Unsecured WLANs pose a security risk for users . Why? As the attackers who are on the same network use a number of ways to ” hijack traffic ” or “hijack accounts” that do not use the https process. Some WiFi suppliers also intentionally send ads to traffic, which can lead to unwanted tracking .

Not forgetting the governments that have begun to systematically monitor users in a few parts of the world, block visits to specific websites, or expose tries at “high treason.” Procedures that threaten freedom of expression and therefore human rights .

After establishing a VPN connection, internet bescherming is certainly routed through a secure server – all over the world. This protects your personal computer from local tracking attempts in addition to from hacking attacks, as well as making sure that your actual IP address is not noticeable to the websites and solutions you visit.

VPN connections: Not absolutely all will be the same

There are different VPN technologies with different encryption types . For example, Point-to-Point Tunneling Protocol (PPTP) is quite fast, however, not as protected as IPSec, OpenVPN, and other SSL / TLS-based protocols. For TLS-based Virtual Private Networks, the nature of the encryption algorithm and the key duration also play a crucial role.

While OpenVPN facilitates many digit combinations, crucial exchange protocols, and hashing algorithms , the most typical implementation for VPN companies with regards to OpenVPN is normally AES encryption with RSA Essential Exchange and SHA signatures. We are able to recommend the following settings:

AES-256 encryption;

RSA essential, with a amount of at least 2048 bits;

SHA-2 cryptographic hash function (rather than SHA-1).

Worth knowing this is actually the fact: The more powerful the encryption , the stronger the effect on the connection velocity. Which VPN technology – or encryption strength – may be the best, varies from case to case and essentially depends upon what data is usually to be exchanged over the connection.

The security requirements of companies are, of course, completely different from those of personal customers. The latter, in the end, usually have to “only” fend off sniffer episodes, unless they fear mass surveillance by cleverness agencies . Then the strongest possible encryption would be recommended.

Geoblocking and firewalls manage VPN

In the buyer sector, VPN tunnels are also regularly set up to circumvent geo-blocking steps . They are designed to limit online usage of certain content to defined regions. VPN providers typically operate server farms all over the world, permitting users to toggle between their “required” IP addresses. For instance, those who usually do not feel like waiting around in Germany for the latest US productions from Netflix could gain gain access to with the help of a virtual private network and a US server.

Nevertheless, there are various other instances where circumvention of geo-blocking or firewalls is well justified. In countries like China or Turkey , governments are blocking access to specific websites and solutions for political reasons. Again, VPN tunnels are used to circumvent the limitations.
