How Do You Make a Private VPN?

in Miscellaneous on November 21, 2019

We all know about VPN. In simple terms, it's a Virtual Private Network and useful for establishing a secure remote access connection across network or networks.

in this blog post I'll discuss 4 ways to make the VPN private so that it won't be available for public use and it can be protected better.

1. Ownership

The first possible solution is to own the whole VPN. Means you will own all of the network infrastructure components, including routers, switches, and cables.

That will be called a trusted VPN in which you'll own all the hardware that supports the VPN. This option is expensive and it's obvious why. If you want to own everything, then your pockets need to be deeper. Right?

2. Lease

The second option is if you don't have deep pockets or if you are tight on networking budget, then lease telco connections. You're going to have dedicated sets of channels which will be used across those leases connections.

This option provided isolation physically, even on those third-party equipments. So, because of the isolation the privacy is maintained. It is more practical option as it's going to a bit less expensive but it's not that much cheaper at all.

This method can be called a trusted VPN as well as you are going to trust the provider of the hosting infrastructure that they are going to protect you against threats like eavesdropping.

3. Encryption on public network

In this option, we are encrypting the public network to protect the privacy. It protects the privacy even on the VPN over the internet. This option is more reliable than the other two options we just discussed. In both of those two options, there are still chances of threats like eavesdropping. 

Furthermore, it's not practical to encrypt the data on the private network to provide privacy but it is the least expensive method. This method is a secured VPN.

4. hybrid VPN

As per the name we know that it's some kind of combination. And yes, you are right. This method of VPN creates a secure VPN over our trusted VPN network. This method of VPN allows you to know the pathway of their connection transmissions as well as gives you the control on those connections as well

As we saw that there is a problem in trusted VPN, the first option. It does not protect against eavesdropping or packets alteration. 

Also we saw the problem in second option as well, in secure VPN. It does not give you the control on the connections nor it does ensure the transmission path of those packets. There is an advantage that it protects the data confidentiality and data integrity.

A hybrid solution is a combination of those two. You must have heard that saying that when two weak persons get together, they creates stronger person as they overcome each other's weaknesses. 

Similarly, when we combine a trusted and a secured VPN techniques we get this potentially more secure solution.
