Two-Factor Authentication Solution for Linux Remote
Login
Problem with existing Remote login authentication
Today’s organizations use various applications for wide range of business needs. Most of
these applications run on Unix or Linux servers. Protecting the remote logins of these
servers is the most important way to secure the infrastructure of organizations. As the
applications run on these servers possess most sensitive data of the organization, using a
weak authentication mechanism of Username/Password does not protect from
sophisticated security threats.
Solution
ArrayShield innovative two factor authentication system – IDAS provides a simple secure
remote access to remote Linux login. 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 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 remote Linux server through SSH the user is shown with the
randomly populated matrix as a challenge in ArrayShield 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 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.
