Virtual Private Network (VPN): It is created by establishing a virtual point-to-point connection through the use of dedicated connections, virtual ‘tunneling protocols’, or traffic encryptions. A virtual private network connection across the Internet is similar to a wide area network (WAN) link between sites.
Significance in business:
VPN is an essential part of IT support and network services. The significance of VPNs is that they provide a connection between two or more places (branches of the same organisation) using an already existing, shared network infrastructure than having to set up a new hardware system for this purpose. The perks of this service is having a private network using public network resources.
In order to avert exposure of confidential business data, VPNs allow only authenticated remote access and uses encryption techniques for data security.
‘Tunneling protocol’ is used to improve VPNs security.
(Note: ‘Tunneling protocol’ is a network protocol that encapsulates packets at a peer level or below. It is used to transport multiple protocols over a common network as well as provide the vehicle for encrypted virtual private networks.)
The essential characteristics of VPN security are:
- Secure encryption of data
- Sender authentication (to eliminate unauthorised access)
- Message integrity to find out illicit manipulation
VPN in mobile technology:
As businesses begin to go mobile, VPN has effective measures to safeguard data in the mobile environment.
Mobile VPNs are used in situations where VPN end points are not fixed to one single IP but travels across many networks. These include Wi-Fi and cellular networks. They have also been widely used in healthcare and by law officials. Hiring experts in medical/legal practice IT support is a sound option for easy and secure access to data
