Two-Factor Authentication Solution for Microsoft OWA
(Outlook Web Access)
Solution
ArrayShield innovative two factor authentication system – IDAS provides a simple secure
Outlook Web Access to company. By using its innovative pattern based authentication it
provides One-Time-Secret-Code for every login transaction without using any further smart
hardware.
In IDAS every user is shown with a matrix on the 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 Outlook. 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 email, 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. These characters form the One-
Time-Secret-Code for the user for that transaction. The ArrayShield IDAS server verifies the user
Problem in exposing email web access using Microsoft OWA
For a successful business, organizations must provide their employees secure access to
their company email accounts. Employees want to check their business email from any
location that business sends them and a successful business offers them that capability.
The value and volume of the information on internet is staggering. This is an appealing
target and your email communications may be at risk. Providing strong security against
everyone on the internet who can visit your OWA login page is the problem.
The usage of a strong, two-factor authentication to protect remote access is a must for
accessing of the company email account from internet.
