Two-Factor Authentication Solution for Squid Web
Proxy
Problem with exposing Emailing system on the Cloud
A web proxy server is a useful service to have on your network, or between your network
and the Internet, as it provides an extra security layer that insulates your users from the
Internet. Squid is a high-performance and relatively secure web proxy server that
includes good caching facilities. It is one of the most commonly used proxy servers on the
Internet. But the weakest link in the otherwise secure web proxy is using
Username/Password credentials to authenticate the user. It does not protect the proxy
server from sophisticated security threats.
Solution
ArrayShield innovative two factor authentication system - IDAS provides a simple secure access
to the Web proxy server. By using its innovative pattern based authentication it provides One-
Time-Secret-Code for every transaction.
In IDAS every user is shown with a matrix which is populated with random characters for every
transaction. User has to choose a pattern which is sequence of cells in the matrix and should
register the same with the system prior accessing. 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 web the user is shown with the randomly populated matrix as a
challenge in IDAS client application. 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 IDAS 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.
