The world has seen quite a lot of change in the past decades especially in the field of technology and it continues to grow its course and has become more and more high tech up to this day. As usual, information sharing has been a vital activity in almost all systems and sectors operating everywhere and the role of internet has never been so important.
Especially in the business sector, where many business firms deal or operate not only in the local and regional arena but as well as in the global scene and logistics, the role of info sharing via the internet is essential to maintain a way to do fast, secure and reliable communications between their offices all around the globe wherever they are located. And with this, almost all companies use the internet for the expansion of their services.
Today, many companies now have their own Virtual Private Networks to accommodate the need of a fast, secure and reliable information sharing between remote offices. The VPN is a technology that uses usually the internet which is a public network to connect remote sites or users together. It creates an encrypted connection that ensures appropriate level of security to connected systems rather than the less secure network. It uses virtual connections via the internet from the company’s private network to the distant sites or employees. This private connection keeps the information of the company circulate only between those who have access to it.
The confidentiality of the data is a top priority of any system and can be protected by encrypting the data. Since the data is being transferred via a public network, protecting the data via encryption or encoding it into a specific form that only authorized computers will be able to decode is vital. This prevents any important and confidential information to be leaked out of the system.
A well-designed VPN uses different methods in order to secure the connection as well as the data itself while being transferred over a public network. Other than encryption, VPNs make sure that the data and the source of data is authentic and authorized so it verifies it and makes sure that the data is not done any alterations during transit. It can also encapsulate an entire data packet within another packet (tunneling) to secure it to be sent over a network.
