IITK Computer Center has installed
a Virtual Private Network (VPN) server to allow access to IITK
computing resources through the public telecommunication
infrastructure and the Internet. VPN employs encryption and other
strong security protocols and allows two computers to create a
private, secure communications tunnel through the Internet. This
ensures that only authorized users can access the IITK network and
that their data cannot be intercepted.
"A VPN is a
private network that uses a public network (usually the
Internet) to connect remote sites or users together. Instead of
using a dedicated, real-world connection such as leased line, a
VPN uses "virtual" connections routed through the Internet in
between two place. from the company's private network to the
remote site or employee.
VPN allows authorized users to
securely connect to the IITK data network from off campus using
various commercial Internet Service Providers (ISPs) (i.e. Satyam,
BSNL, Reliance, MSN, AOL, etc.).
Using VPN, remote users are
connected to the IITK internal network as if they were directly
connected to the campus network. This allows IITK remote users to
access servers and other devices restricted to IITK network users
and isolated from the outside.

is used to provide secure, reliable and proper network
connectivity to mobile off-campus users. They can access all
servers and applications which they can access from within IITK
campus.
