Characteristics Of VPN

When there is a VPN connection , the info is normally transferred between two or more computers on the Internet via a secure tunnel. The computer systems can access each other – as though these were in a local network.

beste internet securityIn past times , virtual private systems were primarily used by companies, for instance, to safely network departments or to provide field staff with usage of the corporate network. Today, VPN is also an important service in the buyer sector, which is usually primarily used to protect against attacks in public areas WLAN networks .

And because the VPN connection will surely not become less important in moments of increasing cyber threats , we have summarized the most important facts about the Virtual Private Network .

Virtual Private Networks: Benefits for Privacy & IT Security

Unsecured WLANs pose a risk of security for users . Why? As the attackers who are on a single network use a variety of techniques to ” hijack visitors ” or “hijack accounts” that usually do not utilize the https process. Some WiFi suppliers also intentionally send out ads to traffic, which in turn can result in unwanted tracking .

Not forgetting the governments that have begun to systematically monitor users in a few parts of the globe, block appointments to certain websites, or expose efforts at “high treason.” Methods that threaten freedom of expression and therefore human rights .

After establishing a VPN connection, beste internet beveiligingssoftware is usually routed through a secure server – all over the world. This protects your computer from local monitoring attempts as well as from hacking episodes, and also ensuring 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 technology with different encryption types . For instance, Point-to-Point Tunneling Process (PPTP) is very fast, however, not as secure as IPSec, OpenVPN, and other SSL / TLS-structured protocols. For TLS-based Digital Private Networks, the type of the encryption algorithm and the key length also play an essential role.

While OpenVPN supports many digit combinations, crucial exchange protocols, and hashing algorithms , the most common implementation for VPN suppliers with regards to OpenVPN is normally AES encryption with RSA Essential Exchange and SHA signatures. We can recommend the next 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 speed. Which VPN technology – or encryption strength – is the best, varies from case to case and essentially depends on what data is usually to be exchanged over the bond.

The security needs of companies are, of course, completely different from those of private consumers. The latter, after all, will often have to “only” fight sniffer episodes, unless they dread mass surveillance by intelligence agencies . Then the strongest possible encryption would be recommended.

Geoblocking and firewalls deal with VPN

In the consumer sector, VPN tunnels are also regularly setup to circumvent geo-blocking actions . They are meant to limit online usage of certain articles to defined regions. VPN service providers typically run server farms all over the world, allowing users to toggle between their “required” IP addresses. For example, those who usually do not feel like waiting in Germany for the latest US productions from Netflix could gain gain access to by using a virtual private network and a US server.

However, there are various other instances where circumvention of geo-blocking or firewalls can be well justified. In countries like China or Turkey , governments are blocking access to specific websites and providers for political factors. Once again, VPN tunnels are accustomed to circumvent the limitations.
