VPN Connection For Solid Internet Security
Also called a “Virtual Private Network,” a VPN is a way to add extra security to your Internet connection. It’s useful when you have a great deal of sensitive files that need to be protected, especially when you’re on a public network (such as a hotel or coffee shop). When you’re using these types of networks, your chances of being hacked are greater. So, creating a VPN connection can give you an extra layer of security to keep your information safe.
When you set up a VPN connection, it creates a “secure tunnel” between your computer and a private network.
A VPN server will facilitate the connection, and it will make sure that no unauthorized user can access the network. Many businesses use this setup to allow their employees to remotely access their servers without compromising security.
VPN networks can be structured in two different ways:
- Outgoing connection – This is a common way to structure a VPN, as it sets up a remote connection to a particular network.
- Incoming connection – This type of connection happens at the network level, as the computer will allow another one to establish a secure connection.
Here is a more detailed explanation of these two types of VPN connections.
Outgoing VPN Connection
With an outgoing connection, you will have to establish your own remote connection, and you can do it on Windows 7. Just type “VPN” in the Search Bar, and click on “Set Up a Virtual Private Network (VPN) Connection.” Then, type in the IP address or domain name of the server in the appropriate box, and click “Next.” If you don’t want to connect at this time, simply check “don’t connect now” before you move forward. You want to type in your username and password in the appropriate boxes, or you can leave them blank. However, you will be prompted to enter them the next time you connect.
When you’re ready to connect to the VPN network, click on the Windows network logo, and click “Connect” under the appropriate VPN connection. Type in the domain name, as well as the appropriate login information (i.e. your username and password), and click “Connect.”
There are many different VPN protocols, so you want to make sure you set up the right one before you try to connect. Otherwise, you won’t be able to access the VPN server.
Incoming VPN Connection
This type of connection comes in handy when you want to set up your own VPN network, and you want to allow other users to remotely connect to your own server. It also works well if you want to create a site-to-site connection, and you can use either a VPN server or a VPN router. Another alternative is to install VPN firmware to a standard router, which works well if you’re on a budget. But a VPN router will have a VPN server built-in. So, you won’t have to install any extra software.
To set up an outgoing connection in Windows 7, go to “Network and Sharing,” and click on “Change Adapter Settings” in the menu on the left. Then, click “File” and “New Incoming Connection.” Select the users to which you want to allow access, and click “Next.”
The last step you need to take before you can connect is to select the Internet protocol you want to use. TCP/IPv4 will be set as the default, but you can always change it if you are using something else (chances are you won’t).
Once you have selected the appropriate Internet protocol, click on “Allow Access,” and you are ready to go.
Understanding VPN Protocols
Before you can establish a VPN connection, you need to make sure you’re using the right VPN protocol.
This is what facilitates the encapsulation and encryption of any data that passes through the network. VPN’s use end-to-end encryption, and it is an effective way to add extra security to your connection. They can also be called “tunneling protocols,” as it creates a secure tunnel between two points on a network. Many VPN protocols use the Point-to-Point (PPP) protocol to facilitate the connection between the client and the server, and it is where both the encapsulation and encryption processes take place.
There are many different VPN protocols, but here are a few that are commonly used.
Point-to-Point Tunneling Protocol (PPTP)
This protocol uses an “IP header” to encapsulate and encrypt any data that moves through the network, and can be used for both remote-access and site-to-site VPN connections. This works whenever a person wants to access a private network from a public area on the web.
PPTP uses “IP datagrams” for the encapsulation process, and it does it through a PPP connection. It uses the Transfer Control Protocol (TCP) to manage the tunnel between the two points on the network, which is where the encryption process takes place.
Layer 2 Tunneling Protocol (P2TP)
Developed by Cisco Systems, this protocol combines elements of both PPTP and Layer 2 Forwarding (L2F). It takes the best parts of both of these technologies, and it uses Internet Protocol Security (IPSec) at the Transport Level to facilitate the encryption process. This combination is often referred to as L2TP/IPSec.
For this protocol to work, it must be supported by both the client and the server, but it is native to most Windows systems.
Secure Socket Tunneling Protocol (SSTP)
This is a fairly new technology, and it uses the HTTPS protocol to facilitate the connection between both ends of the VPN connection. The advantage of this protocol is that it can get through firewalls and web proxies that tend to block PPTP and L2TP traffic.
It uses the Secure Socket Layer (SSL) channel of the HTTPS protocol to manage the encapsulation process, which can allow the use of stronger authentication methods and security measures. Some of them include:
- Better key negotiation
- Stronger encryption
- Improved integrity checking
SSTP uses Port 443 of the TCP protocol to manage the tunnel by which information is passed across the network, and that is where the encapsulation and encryption processes take place.
Using a VPN Provider
If you have files that you want to protect, or if you’re concerned about your privacy on the web, a good VPN provider can keep you safe from hacking or online theft. Whenever you do business on an open network (such as at hotel or coffee shop), you increase your chances of having your security compromised. So, it’s always a good practice to use a VPN to keep your files free from harm.
Tuxler is one the leading VPN providers out there, and we have a variety of plans available – all of which offer the best type of security that money can buy. So, you can be sure to find a VPN service that will fit within your budget.
