Virtual Private Networks (VPNs) are a product of internet technology
and allow an organization to run a private and secure network
restricted only to its authorized locations and personnel while
using the versatile and low cost internet technology framework.
VPNs involve both hardware and software components and emphasise
strongly on security and intrusion prevention.
With a VPN an enterprise can have its entire global operation
integrated into a single network, working effectively as a local
area network but connected across locations through internet
protocols.
The VPN can be configured to allow only restricted and selective
access to external internet and web areas to employees of the
enterprise who are using the VPN.
The VPN also restricts and blocks outside users from accessing
the secure contents of the enterprise's systems and databases.
The VPN through its framework provides a very secure solution
and a combination of hardware and software is used to enable
this result.
With a VPN an enterprise can run email, business applications,
intranets, data transfers and document management systems across
locations. Servers and databases can be accessed and individual
computers can be linked for shared use and access through the
VPN providing complete flexibility and ease of use within the
users of the network.
At the same time, the VPN will ensure that any location or computer
that is not authorized for access to the VPN is blocked at the
outermost layer of access to provide high security and intrusion
prevention.
Intrusion detection hardware and software, firewalls, packet
monitoring, filters, anti-virus measures, spam protection devices
and others form components of a comprehensive VPN system.
