Two Factor Authentication for VPN

Two-Factor Authentication Solution for VPN


Problem with existing VPN authentication
For a successful business, organizations must provide their employees with secure
remote access. The preferred way for companies to allow secure remote access is via a
Virtual Private Network (VPN) over existing Internet connections.

Although, VPN technology ensure the privacy of data transmission over public domain by
creating an encrypted “tunnel” through the public network, but do not strongly protect
unauthorized access to the organization’s assets. This happens because simple username
and password is used to protect the access to most VPNs. So, information that is secure
while in transit may just be ending up in the wrong hands at its final destination.

Solution
ArrayShield innovative two factor authentication system - IDAS provides a simple and secure
remote access to Organization’s network infrastructure using VPN technology. By using its
innovative pattern based authentication it provides One-Time-Secret-Code for every login
transaction.

In IDAS every user is shown with a matrix on the VPN login screen which is populated with
random characters for every transaction. User has to choose a pattern which is a sequence of
cells in the matrix and should register the same with the system prior accessing the VPN. A
translucent card is provided to each user which has a similar structured matrix with transparent
and opaque cells and some random characters imprinted on the opaque cells. Each card is
unique in terms of the position of the opaque cells and the characters imprinted on them.

At the time of accessing the resource through VPN the user is shown with the randomly
populated matrix as a challenge. The user overlaps the translucent card on the shown matrix
and will key in the characters present in the chosen pattern in the same order as a response.
These characters form the One-Time-Secret-Code for the user for that transaction. The
ArrayShield server verifies the user credentials by comparing user’s registered pattern and the
pattern values entered by the user. Access is given to the user if the user credentials are valid.
