VPN and Communication Security
The VPN is a very vital tool in the communication interactions of both companies and individuals. The VPN is designed to establish a network that is secure even which is made possible by creating a virtual tunnel which is encrypted on the public network which in most cases is the internet. Before that advent of the VPN businesses would rent private lines which they would use to connect branches of their offices including those based abroad but this would come at a cost owing to the costly nature of connectivity within a broad range. The VPN connection therefore has made it easy for most companies to operate on a secure platform while cutting on costs. In fact, the services that are provided by the VPN service provider are an equivalent of services that are offered by leased lines.
Other than the business as well as corporate use, the VPN connection could as well be used by individuals who would like to access some of the services that are not accessible through their regular ISP like VoIP or even a blocked firewall or even bypassing restrictions that have been put on certain websites that touch on the censorship policies and issues. In this case therefore a connection is established between the VPN service provider and the user where the VPN Company is mandated to provide private and secure browsing via an encrypted connection, access to applications and websites that have restrictions also hide the IP addresses of the user when they visits a site.
The VPN service targets individuals who spend too much time worrying about how secure they are when they are on the internet by providing them this assurance. In return users of the VPN connection worry less about sending their data over the internet as is the case with VoIP as it is secured. With the VPN connection in place not even the professional hackers can gain access to your system as they would for a system that is unprotected. Thus, the VPN service is especially recommended for companies that deal with information that is very sensitive. In fact, having a VPN connection clears fears of possible eavesdropping by outsiders especially when using the VoIP services. A VPN connection has the capability of establishing communication that is secure through either of the numerous protocols available. The VPN also uses authentication besides these secure tunnels. In order to be able to connect to the established VPN connection users must have usernames as well as passwords. Digital certificates may also be used while in some instances there may be need for repeated authentication. Users could also be asked for alternative passwords or Personal Identification Numbers (PIN) which are stored in the hardware. These PIN number changes on a very regular basis and without it, no user can access the secured VPN service connection. It is therefore important that users also be careful with these information because without it then they will not be able to access the secured service.
