Understanding how its system works
The Virtual Private Network or VPN is widely used today especially for businesses and corporations with huge networks and storage. It exists on a tightly walled and invisible area but is very much accessible. It services the company exclusively with its own network, internet access and data storage, but can be used outside work as well, preferably on a broadband online connection.
VPN uses the concept of a separate independent network and storage area for retrieving highly confidential and important information and files. Although it is hidden from public connections, this enclosed hub is directly accessible through it as well. It essentially acts as a secure cloud that can be accessed anywhere, anytime.
Why go VPN?
Widely used but not a popular choice, the VPN or Virtual Private Network is suitable for any organisation running a huge network and database, but cannot be stored anywhere, but in the company’s own system only. It has been used for handling company files, sites with secure online payments, VoIP or voice over the internet phone, online broadband networks and for huge databases and archiving.
Despite the exclusive static location of this network, it remains an all open full access area that is available anytime with the right portal access only. The VPN can be accessed through any preferred high speed or broadband access or connection, even on NBN, and provides a reliable networking and data hub.
The VPN is a separate network like the cloud, and performs the same way, with higher security involved. The network has a connection to the public access network online and uses this as a bridge for authorised users from the company to open their files, programs and apps from the invisible network, from say, their laptops or home computers or even smartphones and mobiles (with limited options).
The bridge is the actual connection, but no other individuals or organisations have access to it since there is only one portal with deep encryption. It is also closed and invisible to public use as well. The structure is similar to a cloud service except that no third party is involved here. There is also local encryption involved from the company or organisation who owns and maintains it.
The Issue of VPN Security
VPN is not only used by companies and such, online businesses also use it for high security SSL or Secure Sockets Layer systems for online payments. Anything that uses credit cards, Paypal and other electronic payments use this system for added security and encryption of customer data. Other companies involved with a high speed and broadband connection also use it for networking with VoIP or voice over the internet phone, among others. It is a more reliable network in some cases for these functions.
With this, the issue of security is taken care of by protecting the data through encryption and other tight security software. In the event that someone is able to break through and hack, the information is in packets and is still encrypted, ensuring no information can be taken from it for double security. This works for both stationary devices (personal computers or macs) and all compatible portables (smartphones and mobile that have been configured). Other companies use their VPN with added security options, such as combination of VPN tunneling with Security Gateways, which prevent high level intrusion and hacking.
