VPN stands for virtual private network, and it is a form of technology that builds a secure network connection over a public network, such as the World Wide Web, or even inside a service provider’s private network. Various institutions such as government agencies, schools, and large corporations use the services of a VPN, so that their customers will have the ability to connect securely to their personal networks. The Same as with wide area network WAN, VPN technology have the capacity To connect several sites together, even those divided over a huge distance. With the case of educational institutions, to connect campuses with each other, even those located in a different country, VPN is used for this purpose.
To use a virtual private network, users are required to provide a username and password for authentication. Some vpn reddit connections also have to be provided a PIN personal identification number, usually composed of special verification code, which are available in the kind of a token. The stated PIN changes every couple of minutes, and is paired with the account’s username and password. Even if the token is stolen, it will be useless without the aforementioned details
Since it uses 128 bit keys to encrypt traffic, PPTP or Point-to-Point Tunnelling Protocol is regarded as a less secure protocol than others. But for many users, this may already do, especially when they connect with a VPN just for private use.
A more secure choice is Layer 2 Tunnelling Protocol or L2TP, as it works with IPSec protocol which uses better protected encryption algorithms than what’s used with PPTP. The combination of the 3DES encryption algorithm and a 168 bit keys are what make L2TP encryption stronger.
Secure Socket Tunnelling Protocol or SSTP is considered the most secure of all protocols, as it is a SSL VPN protocol, and uses 2048 bit encryption keys, in addition to authentication certificates. The Reason it is the most powerful out of VPN protocols is that it Has the capacity to function even on network environments that blocks VPN protocols. Some countries such as Belize do not enable the use of VPN connections, and there are particular companies that do this too. VPN using SSTP protocol is helpful for these kinds of situations.
With the above information, you are able to match up the kind of VPN protocols that could work best for you. If you only need the service as you wish to feel secure and safe when surfing the internet in your home or hotspot connections, PPTP will work well with you. If you want more protection than that which a PPTP can supply, you simply need to go to another one to reply you needs.
