What is An Agreement Hosting Level Service VPN All About?

First, let us tackle the acronym VPN: What does that stand for? VPN is used to refer to virtual private networks. A virtual private network is defined as a communications network which is channeled via another network. The communications network is by itself used for a specific network. A good example of a virtual private network would be communications with security features that use the public-access system of the Internet. However, a virtual private network does not necessarily have obvious security features.

So, you may be asking yourself, just what is an agreement hosting level service VPN then? Well, it may mean that a service level agreement was formed between the virtual private network service provider (the host that does the indicated hosting) and the virtual private network itself. A VPN is important because it offers a kind of functionality that a user community needs and avails of through that network.

When does a VPN become important to enterprises? Since a VPN relies on another network for its own network to function, the sharing of infrastructure may result in lower capital expenditures (or basically lower costs) compared to the use of dedicated facilities to house traditional routed networks. Users who stand to benefit from a VPN would be minor home-based workers, telecommuters who use facilities where the opportunity arises, and enterprise offices in different locations. One advantage of the VPN is that service quality and security can be programmed or designed specifically for the specific applications that the VPN is to be used for. Since infrastructure is shared with a host network, the VPN can be customized for needs that should be immediately met. In addition, if facilities and support systems are outsourced, then operational expenditure goes down significantly.

A disadvantage inherent to VPN is that if VPN is distributed to facilities that lack the security controls of traditional facilities (such as small home offices, telecommuters, and residences which form the new wave of occupational facilities), sensitive data may not be adequately protected from threats. Security protocols for a VPN should be considered carefully before use of a VPN is advocated, as a result. One reason security protocols are lacking in non-traditional occupational facilities such as your home office is that there is no professional systems administrator who has the adequate training for the security function. This is why some organizations that allow their employees to be telecommuters or home-based workers, such as health care organizations, ask their employees to have two different lines installed: one line will be devoted purely to sensitive information, while the other is for less-secure data.

There are two ways in which security can be guaranteed when a host network hosts a VPN: first, the host network should possess the necessary security features so that end users of a VPN can trust it. Second, the VPN should have security controls integrated into its network system rather than rely on the host network security protocols. In the final analysis, it is the end user who will suffer if security controls on either the host network or the VPN are not assured.
