VPN Services- VPlus Networks |
| Managed VPNs (Virtual
Private Networks) are a relatively new technology that allow
two or more private networks (or computers) to securely connect
over the Internet. In business terms, one reason a company may
look to install a VPN is to allow managers or sales reps in the
field to safely connect to the office network / server and transfer
files, send and receive their email, etc. In essence, a managed
VPN allows an organisation to extend the corporate network to
include all remote locations, as well as any home offices, using
the Internet. |

| VPN technology
is based on the concept of tunnelling. In essence, a VPN tunnel
is a link between two authenticated devices over the public Internet.
In simple terms, if an organisation has users in Glasgow , users
in London and an office in New York , a VPN could be created
to virtually connect each user to the central site. A Virtual
Private Network uses encryption and other security mechanisms
to ensure that only authorised users can access the network,
and that the data cannot be intercepted by unauthorised external
sources. With a managed Virtual Private Network, it is possible
to combine VPN tunnelling and encryption to create a secure corporate
extranet, whilst reducing the burden on in-house network security
teams. |
| Another
key feature of a managed VPN is the scalability of the solution.
Whether the company is upsizing, or downsizing, a managed VPN
allows you to add or removing services or users quickly amd
simply. The VPlus Managed VPN solution uses provisioning tools
that enable VPNs to be created or modified easily with minimal
impact to individual services or users. As part of the VPlus
Managed VPN solution, a team of dedicated, qualified technical
engineers will proactively monitor each VPN service, reducing
the burden on the end user organisation’s technical department.
A significant benefit of the VPlus offering is we take over
the responsibility for keeping pace with the emergence of new
vulnerabilities and ever more sophisticated threats, and to
proactively respond to these. |

Secure Socket Layer Technology Technical Overview |
Use of Secure
Socket Layer technology is becoming an increasingly popular
way to provide Virtual Private Networks.
Secure Socket Layers (SSL) technology is the industry standard protocol for secure,
remote-access communications and transactions. SSL creates
a secure remote access channel between the VPN access device
and the end user – be they a teleworker, mobile worker etc.
|
| SSL
provides Network Security in the following ways: |
Message Privacy
- SSL provides message privacy by encrypting all information exchanged between the
SSL VPN access device and the end user. To securely transmit
the session key to the consumer, the SSL Virtual Private Network
access device encrypts it with the client's public key. Each session key is used only once, during a single session with a single end
user. These layers of privacy protection ensure that information
cannot be viewed if it is intercepted by unauthorised parties.
Message Integrity - SSL also provides message integrity. When information is sent, the sending and receiving
computers each generate a code based on the message
content. If even a single character in the message
content is altered en route, the receiving computer
will generate a different code, and then alert the
recipient that the message is not legitimate. With
message integrity, both parties involved in the transaction
know that what they're seeing is exactly what the other
party sent.
VPlus
Networks’ managed VPN service provides additional features to enhance the security, availability and visibility of the solution. |
