The Ultimate Guide To VPN

The Ultimate Guide To VPN

beste internet securityIf there is a VPN connection , the info can be transferred between several computers on the Internet via a secure tunnel. The computer systems can access one another – as if these were in a local network.

In past times , virtual private networks were primarily utilized by companies, for instance, to safely network departments or even to provide field personnel with access to the corporate network. Today, VPN is also an essential service in the consumer sector, which is primarily used to protect against attacks in public WLAN networks .

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

Virtual Private Systems: 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 variety of techniques to ” hijack traffic ” or “hijack accounts” that usually do not utilize the https process. Some WiFi suppliers also intentionally send advertisements to traffic, which in turn can result in unwanted tracking .

Not forgetting the governments that have started to systematically monitor users in a few parts of the world, block visits to certain websites, or expose attempts at “high treason.” Procedures 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 along with from hacking attacks, along with making sure that your actual IP address is not visible to web sites and solutions you visit.

VPN connections: Not all will be the same

There will vary VPN technologies with different encryption types . For example, Point-to-Point Tunneling Protocol (PPTP) is very fast, but 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 size also play an essential role.

While OpenVPN supports many digit combinations, key exchange protocols, and hashing algorithms , the most common execution for VPN companies with regards to OpenVPN is usually AES encryption with RSA Essential Exchange and SHA signatures. We are able to recommend the next settings:

AES-256 encryption;

RSA key, with a length of at least 2048 bits;

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

Worth knowing here is the fact: The more powerful the encryption , the stronger the impact on the connection quickness. Which VPN technology – or encryption strength – is the greatest, varies from case to case and essentially depends upon what data is to be exchanged over the connection.

The security needs of businesses are, of course, completely different from those of personal consumers. The latter, in the end, will often have to “only” fend off sniffer attacks, unless they fear mass surveillance by cleverness agencies . Then your strongest possible encryption would be recommended.

Geoblocking and firewalls manage VPN

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

However, there are additional situations where circumvention of geo-blocking or firewalls is certainly well justified. In countries like China or Turkey , governments are blocking access to certain websites and services for political reasons. Once again, VPN tunnels are used to circumvent the restrictions.
