Two-Factor Authentication Solution forLinux Remote LoginA r r a y S h i e l d | i n f o @ a r r a y s h i e l d . c o m Page 1Two-Factor Authentication Solution for Linux RemoteLoginSolutionArrayShield innovative two factor authentication system – IDAS provides a simple secureremote access to remote Linux login. By using its innovative pattern based authentication itprovides One-Time-Secret-Code for every login transaction.In IDAS every user is shown with a matrix which is populated with random characters for everytransaction. User has to choose a pattern which is sequence of cells in the matrix and shouldregister the same with the system prior accessing. A translucent card is provided to each userwhich has a similar structured matrix with transparent and opaque cells and some randomcharacters imprinted on the opaque cells. Each card is unique in terms of the position of theopaque cells and the characters imprinted on them.At the time of accessing the remote Linux server through SSH the user is shown with therandomly populated matrix as a challenge in ArrayShield IDAS client application. The useroverlaps the translucent card on the shown matrix and will key in the characters present in thechosen 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 bycomparing user’s registered pattern and the pattern values entered by the user. Access is givento the user if the user credentials are valid.Problem with existing Remote login authenticationToday’s organizations use various applications for wide range of business needs. Most ofthese applications run on Unix or Linux servers. Protecting the remote logins of theseservers is the most important way to secure the infrastructure of organizations. As theapplications run on these servers possess most sensitive data of the organization, using aweak authentication mechanism of Username/Password does not protect fromsophisticated security threats.
