Tuxler | Virtual Private Internet
A VPN allows a user to create a more secure Internet connection on an unsecure network. It can be useful for anyone who is concerned about hacking or online theft on an open Wi-Fi connection, but someone may also want to keep his or her online activity private. This person may also be traveling abroad and is looking for a way to bypass certain geographical restrictions. Whatever the case may be, a VPN can help you create a virtual private Internet connection.
A Virtual Private Internet Connection with VPN Technology
Also called a “Virtual Private Network,” a VPN uses end-to-end encryption to secure any data that gets transmitted from one point to another. It’s useful if someone is trying to access a private server from a public network, because it creates a secure tunnel of communication through which data can be transmitted.
With end-to-end encryption, you can restrict access to people who have the proper decryption key. Without it, it would be close to impossible to decipher the encrypted data, which is why it’s such a powerful method of creating a virtual private Internet connection.
It’s a useful technology for anyone who is concerned about privacy or security on the web, and many companies use it to allow their employees to access their servers while they are at home or on the go. Anyone can use VPN technology to create a more secure Internet connection, especially if they do business on an open network.
VPN’s can also bypass any geographical restrictions that may be in place by the government of another country. This is called “geo-blocking,” and it can be useful for someone who travels abroad.
Understanding VPN Protocols
A VPN protocol can facilitate the encapsulation and encryption of data being transmitted across a network, and its purpose is to create a secure tunnel through which it can travel. They are sometimes called “tunneling protocols,” and many of them use the Point-to-Point Protocol (PPP) to establish the connection between different points on the network.
There are many different VPN protocols, but there 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 it can be used for both remote-access and site-to-site VPN connections. A person can use this protocol to connect to a private server from a publicly-accessed portion of the web.
PPTP uses “IP datagrams” to encapsulate the data, which is done with a PPP connection. The tunnel is managed via a TCP connection, which is where the encryption process takes place.
Layer 2 Tunneling Protocol (L2TP)
Developed by Cisco Systems, this protocol uses a combination of PPTP and Layer 2 Forwarding (L2F) to add an extra layer of security at the Transport Level. L2TP takes the best elements of both technologies and puts it into one protocol, and it uses Internet Protocol Security (IPSec) to encrypt the data. that’s why it’s sometimes referred to as L2TP/IPSec.
The advantage of this protocol is that it has a more robust architecture than PPTP, but it must be supported by both the client and the server. Fortunately, it is native to most Windows systems.
Secure Socket Tunneling Protocol (SSTP)
This is a newer technology that uses the HTTPS protocol to facilitate the encapsulation and encryption process. The advantage of SSTP is that it can get through firewalls and web proxies that have been known to pass through PPTP and L2TP traffic.
It uses the Secure Socket Layer (SSL) channel of the HTTPS protocol for the encapsulation process, which allows the VPN server to use stronger authentication methods. This results in better key negotiation, encryption, and integrity checking.
This is a free program that uses open-source VPN technology to create secure point-to-point and site-to-site connections for its users. It has its own custom security protocol that uses SSL/TLS for key exchange. It has the ability to bypass many Network Address Translators (NAT’s) and firewalls, and it has a lot of security and control features.
With OpenVPN, users authenticate each other with a “pre-shared secret key,” and every authorized person will receive an “authentication certificate.” It uses OpenSSL to encrypt the data, which has many robust security features.
Using a VPN Provider for a Virtual Private Internet Connection
The purpose of a VPN provider is to offer end-to-end encryption to people, so they don’t have to go through the hassle of setting it up themselves. It helps people create a virtual private Internet connection that they can use no matter where they are.
Using a VPN service is a good practice for anyone who does business on an open network (like a Wi-Fi hotspot at a coffee shop), because your chance of being hacked increases when you’re using them. It’s good for someone who is concerned about his or her privacy on the web. You may be traveling, and you want to find a way to bypass any geographical restrictions. A VPN provider can divert your location to make it look like you’re somewhere else.
