Structure and varieties of VPN technology 翻墙 in China
by Bolda Boldana BoldaStructure and varieties of VPN technology 翻墙 in China
The whole technology works in two layers. The first is the internal network, the second is the external network. When you connect to the technology, the system identifies your network, and then sends a request for authentication. This technology is very similar to authorization in some social network, only here everything is carried out through secure protocols and without the participation of the provider.
Virtual networks themselves are also divided into several categories. The main classification is based on the degree of protection, that is, the user can use both paid and free VPNs.
The difference between them is a secure connection. For example, systems with a subscription will give you secure protocols such as PPTP, IPSec, and others. While free VPNs often provide only "trusted" channels. That is, your network itself should be highly protected, and a VPN will only increase the level of protection.
To be honest, the biggest disadvantage of free VPN services is not even security, but stability and connection speed. Using a free VPN, the Internet is likely to work very slowly, and not always stable.
Subscription to paid VPNs does not exceed $ 10 per month, but not every user needs it. For normal tasks, it makes no sense to purchase Premium accounts, and standard features are enough.

Cheerful manIt should be understood that a point-to-point connection allows each connection to work in such a way that it is practically impossible to obtain all contacts to third parties. We should not forget that the VPN server allows you to create high-quality encryption of all traffic and all data. The keys are used for encryption, which after some time change, this increases the security of user data, preventing outsiders from using them for their own purposes. Feb 5th 2020 05:17 |

The best of the bestThere is one more advantage to this type of compound. It is expressed in the ability for one or more users to use the "secure Internet", and also in that entire offices and companies have the opportunity to visit the global network under VPN protection. Consider this option when a separate company has a DSL address. In this case, of course, it is preferable to use a VPN rather than establish an Internet connection through a connection such as Feb 5th 2020 05:19 |

Cheerful manAs for the disadvantages of VPNs, they also exist, and also in limited numbers. The main disadvantage of such a network is the complicated configuration of its network, and the difficulties in supporting and implementing such a network. For the most part, the use of this type of connection implies the use of very serious systems for data encryption Feb 5th 2020 05:20 |

In short, choosing the best VPN is not possible. Some succeed in security, others offer a large selection of servers from a large number of countries, while others have unique features that competitors do not have. When searching for a VPN, be sure to think about what you want to use it for, and choose the one that suits your requirements. In addition, read the reviews of the VPN you are interested in; this will facilitate the choice.
