VPN – As Secured As a Baby in a Womb
The world is fast changing and Business corporations all over the world are taking various steps to take their organization to a completely different level. They are not hesitating to employ various methods like widening the range of their target audiences by reaching out to them even if they are in different countries, outsourcing their work which definitely provides low operational costs not to mention plenty of time for corporations to focus on their core business. For those companies which are expanding there base and making their presence felt in different parts of the globe many a problems seems to arise. They might have a tough time retaining their target consumers or keeping track of their employees.
The foremost reason behind a firm not succeeding in their priorities is a communication gap between them and their clients. As communication is the main bridge between a client and a firm and the firm and success, companies can not rest assuming that everything will be alright as time heals everything. They need to maintain a fast, reliable and secure communications with there offices and clients irrespective of where they might be. These kind of specific hassles are completely eliminated by the use of dedicated VPN or Virtual Private Networks.
A VPN is a private computer network that is based in an overlay on top of an existing network and uses a public network such as the internet to create a private, secure communication scope or to connect remote sites or users together. It serves many purpose such as providing secure extension of a private network into internet (which is usually insecure and prone to attack), using a virtual connection instead of a real connection such as a leased line. It can be a remote access or a site to site network. But in either case we need specific software and hardware to build a VPN. For instance, we need software for each remote user, a dedicated hardware (concentrator), a VPN server to be used by the service provider, secure PIX firewall etc. and hardware like SEP modules. VPN optimized routers etc.
Coming on to the advantages of a VPN or the ways in which it can benefit a business to succeed, VPN are a cost effective medium (which saves the company a large sum), they are mobile and provide security to its users (which increases client’s trust in the company), it provides a vast geographical connectivity which enables the employees to log in at places comfortable to them (thereby increasing connectivity), they also offer broadband networking, telecommuter support etc.
For compatibility reasons most Cisco networks use Cisco VPN software, but never the less irrespective of whichever VPN client used, an SSL (Secure Sockets Layer) should be set up for maximum efficiency and should contain proper security measures to avoid hacking of personal data of the client. Priority should be given to striking the right balance between proper functionality and smooth usage (for yourself and the end users who will be accessing the network). Thus VPNs are here to stay and have immense growth opportunities so why not make them to work for you.
