A VPN is a great way to protect your online data transmission. That’s why it can be an excellent choice for creating a private Internet connection, as it uses end-to-end encryption to create a more secure network. A VPN is a group of computers that are linked together so they can share files and other resources from within a private network, and it can be useful in securing certain files or other pieces of electronically stored information. It’s an important thing for any business to consider, especially if there is a great deal of information being passed between members of an organization.
Creating a private internet connection with a VPN
A VPN is useful if you want to connect to an open network like a hotel, restaurant, or coffee shop because you are more likely to be hacked when you are on an open Wi-Fi connection. It can add an extra layer of security, which can go a long way in keeping your information safe from online theft. These can include, but are not limited to the Files, Applications, and Printers. There may be other company resources that an employee may wish to access, and a VPN can create a private Internet connection so there is no lack of security. This setup can be useful if you have employees who do a great deal of traveling. There are many different VPN protocols, but here are a few that are commonly used.
Point-to-Point Tunneling Protocol (PPTP) is used as an “IP header” to encapsulate and encrypt any data that passes through the network, and can be used for both public-access and site-to-site VPN connections. One end is connected to a public network (such as the Internet), and the other is connected to a private network like a corporate intranet. PPTP uses “IP datagrams” to encapsulate the data, which is done over a PPP connection. The tunnel is managed with the TCP protocol, and the data can be encrypted as it passes from one end to the other.
Layer 2 Tunneling Protocol (L2TP) is developed by Cisco Systems, L2TP uses a combination of PPTP and Layer 2 Forwarding (L2F) to encapsulate and encrypt any data being passed through the network. The advantage of this protocol is that it adds an extra layer of security at the transport level, and it incorporates the best elements of both PPTP and L2F. L2TP also uses Internet Protocol Security (IPSec), which is why it is often referred to as L2TP/IPSec by many IT professionals and network administrators.
Secure Socket Tunneling Protocol (SSTP) is a new technology that uses the HTTPS protocol to pass traffic through firewalls and web proxies that can block PPTP and L2TP traffic. SSTP uses the Secure Socket Layer (SSL) channel of the HTTPS protocol to encapsulate the data, which can allow the use of stronger authentication methods. It can also allow the use of better key negotiation, encryption, and integrity checking. SSTP uses port 443 of the TCP protocol for tunnel management procedures, which is where the data can be encapsulated, encrypted, or both. To know about the privacy using VPN read more here.
