Virtual Private Ntwork Feature and Benifits

1
Virtual Private Network (VPN) Feature and Benefits
2
Virtual Private Network (VPN)

• A virtual security appliance is a computer
  appliance that runs inside virtual environments.
  It is called an appliance because it is
  pre-packaged with a hardened operating system and
  a security application and runs on a virtualized
  hardware.
• Virtual security appliances are playing a
  significant role in meeting your expectation
  today and will continue doing the same in the
  future.

How Does VPN Function

• As soon as you connect to the VPN, the VPN client
  interface is launched on your computer. This in
  turn will require you to fill in your credentials
  with a remote server.
• This helps both the systems in verifying each
  other. Whats more, as the Internet communication
  is encrypted, it ensures that the integrity of
  data is maintained throughout its path.

Why Your Business Needs A VPN

• A VPN service changes the IP address assigned to
  the computer. This enables you in accessing sites
  which may be banned in your country. This can
  prove to be of great help if your business
  requires specific data. For example, you are a
  player operating in the media industry and are
  working on a certain story. It is quite possible
  that during the course of your research, you may
  need some information which has been censored by
  the state. This problem will be taken care of if
  you are using a VPN.
• Using a VPN helps you to provide the much needed
  access to your employees to remote devices such
  as files, printers, applications, etc. via the
  Internet. You also do not need to take any extra
  measures in order to secure the network.
• Using a VPN will also help you in connecting
  multiple networks, hence, making it possible for
  you to connect your branch offices located across
  the globe (if this is the case).

Types Of VPN

• IP security protocol or IPsec is one of the types
  of VPN connections that is available. IPsec uses
  Layer 3 of the OSI model to encrypt the data.
• The second type of VPN connection available is
  Layer-2 Tunnel Protocol or L2TP. A point to point
  tunnel protocol along with Cisco Layer-2 is used
  for this. Secure Socket Layer or SSL is the third
  type of VPN connection that is used. SSL depends
  on certificates to verify the identity of a
  server or a computer.

Who Does VPN Work?

• Most people dont have a clear idea about how VPN
  works. A general perception is that when you
  connect through a VPN, your data is secured and
  cannot be accessed by anyone else. However, if
  you look into the technical side of it, VPN uses
  the technique of tunneling. When data is sent
  through internet, it is divided into packets. The
  data is further divided into bite sized pieces
  to send with ease and convenience. VPN uses
  tunneling protocol and encryption to secure your
  data.
• In order to prevent your data from being accessed
  by someone else, the data will be encrypted.
  Encryption is a process where the encoded data
  can be decrypted only by an authorized computer.
  Anyone who tries to intercept the data on public
  network will not be able to read it. Public-key
  and symmetric-key are the two main types of
  encryptions that are used.

Selecting the Right VPN Service

• Businesses with offices and presence across the
  world feel the need of connecting with their
  employees at different locations through a fast,
  secure and reliable way. This is where a Virtual
  Private Network (VPN) comes into picture. It is a
  group of computers or discrete networks connected
  to each other over a private network which is the
  Internet. While businesses can connect remote
  datacenters through VPN, individuals can use it
  to access network resources without being
  physically present on the same LAN.

Advantages Associated With Using A VPN Service

• The data that you send and receive is encrypted.
  Hence, Using a VPN network ensures that your
  communications are not picked up by any
  unauthorized party. This also helps in
  maintaining the integrity and confidentiality of
  the data.
• You do not need to be an expert in order to set
  up and use a VPN system. These systems are user
  friendly and easy to understand.
•  
• Service providers have come up with various
  flexible plans like a monthly or an annual
  subscription plan. You can choose from among
  these options the plan best suited to meet your
  business needs. This has also helped the
  providers to cater to the varied needs of their
  VPN clients.

10
Disadvantages of VPN

• VPNs require an in-depth understanding of public
  network security issues and proper deployment of
  precautions.
• The availability and performance of an
  organization's wide-area VPN (over the Internet
  in particular) depends on factors largely outside
  of their control.
• VPN technologies from different vendors may not
  work well together due to immature standards.
• VPNs need to accomodate protocols other than IP
  and existing ("legacy") internal network
  technology.
