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.

VPN, or virtual private network services act as a secure connection over an insecure connection called the internet. VPN is a secure layer of software which has the capability of absorbing some insecure contents. VPN services are of two types:

The remote access VPN and site to site VPN. Both of these services can be used in banking services in order to provide secure and safe transaction facilities to their customers. It’s site to site VPN gives you a secure connection between two or more locations across the open internet. By using site to site VPNs services banks can be more secure and safe. Transferring amounts can cost a lot to banks by site to site but, the virtual private network services can reduce this amount. Now, one can use cheaper means for example, domestic network or broadband which is the hiring expensive plan or sites for transferring your money with security.

The next type is remote access VPN service. It is also known as dial up or VPDN and used by the bankers and staff members of banks who are located at remote places. They can get in touch with the bank and can perform their transactions with the same level of satisfaction and safety. By using a VPN service you can connect to an office network via any means such as dial up connection or any ISDN lines from anywhere in the world and no one can track your activities. These are highly secured and reliable services and most banks are using them in order to make their process more authenticated and transparent.

In VPN services, especially in banking, advanced encryption and security techniques are being used to ensure security to a great extent. It facilitates work and permits the computers and other hardware to establish a secure and reliable connection over an insecure connection. The internet is very insecure and banks cannot afford to lose private information due to any fault in their system because of insecure internet connection. Virtual private network, VPN, will overcome this limitation and provide more secure and stable connection at low prices.
