Adaptive Risk Authentication and the IRM Pillar Dynamic Intelligence

The requirements and demands on Identity and Access Management solutions have shifted. With a fresh pair of eyes, the industry calls this Identity Relationship Management (IRM). One of the pillars defining IRM is Dynamic Intelligence rather than Static Intelligence. Static Intelligence covers what we already know about a user, whereas dynamic intelligence includes things that might be spontaneous, such as geographical login location.


In the past, access patterns have been predictable. Employees have logged in from their usual desktop PCs, and have accessed the applications required to perform their job tasks. As the modern world has changed user behavior, predictability is no longer the case. Enterprise users access applications and services from a wide variety of locations and devices, including laptops, smartphones and their traditional desktop PCs. Looking beyond the enterprise at consumers, these users can leverage any device, from their home TV to their car.


A modern IRM solution must be able to cater for these dynamic access patterns and must understand the myriad of circumstances in which a user accesses a particular service, in order to grant access. Ultimately, authorization must also be dynamic and must provide the appropriate content or entitlements “on the fly”. A concrete example is that of a user trying to access services when logged in from a different country. An adaptable IRM system will adjust to the particular circumstances and will potentially ask for additional authentication beyond simple credentials.

This use-case is something that can be addressed with the latest release of
ForgeRock OpenAM (introduced in OpenAM 10), which provides an adaptive risk authentication module. Adaptive Risk Authentication is not an authentication mechanism but rather identifies potential risks (such as logging in from a different country in the sample above), assigns a risk score and then determines whether logging in should require additional means of authentication. The additional authentication requirement can be anything from requiring a one time password to using some type of hardware mechanism.


An authentication mechanism that adapts to specific circumstances is a perfect example of the IRM pillar of “Dynamic Intelligence” and adds additional assurance that a user really is who she claims to be.


Some of the risks that can be defined and dealt with dynamically include IP Ranges, IP History, known cookies (and values), time since last login, profile attributes and their values or geographical location.


Pioneering risk-based, adaptive authentication has always been the domain of the financial sector. However, as this technology has become mainstream, more and more organizations are deploying adaptive authentication to deal intelligently with the growing number of mobile users, to mitigate the risks of users who fraudulently claim to be someone else in order to potentially commit malicious actions.
