It’s one of the most asked questions when it comes to transporting data, especially through the internet. It’s not really that expensive to construct a LAN, but connecting to another LAN, in a safe and private manner is time consuming and expensive. So, how can a individual, business, or corporation, create these connections to another LAN without leasing (public) internet lines?
Bridges are built to connect LAN’s to each other. It is like using a “leased” line, but with much more security and is certainly more dependable and reliable. Now, if two businesses need to connect over a large distance, the cost could be too great to generate this length of secured line.
But let’s discuss the value of using a VPN with-in a smaller geographical network connection. This VPN is a secure, dependable, fast, and able to expand as your business grows. Each remote office or location is able to send or receive data back and forth and know that it’s a safe path. The name for the growth is ”Scalability”. If a VPN is properly configured, some of the technology and terms recognized would be: Encryption, Firewall, AAA Server, and IP Sec. Let’s talk about each one for a brief moment.
“Encryption”is where all of the data sent from one computer to another or vice versa, is encoded into a manner that is only readable by the other computer.
“Firewall” is your safeguard barrier or a wall between your private network and the Internet. They can be configured to restrict ports, what types of data are allowed to pass through the Firewall.
“AAA Server”stands for Authentication, Authorization, and Accounting. Basically, the AAA Server checks who you are, what you’re allowed to do, and what you actually can do. This is perfect for auditing the use of the PC on the network and provides a greater secure entry into the VPN.
The IP Sec is the Internet Protocol Security gives an enhanced level of security to provide a better encrypted algorithm and more detailed authentication.
VPN’s are a smart, safe, and more secure way of connecting people, PC’s, and businesses together.
