A system, method and computer program product that utilizes measurements for the authentication of users to enterprise resources. The system includes an authentication server that stores the engine and collections of data required by the system to authenticate users. The collections of data include templates, policies, groups, device IDs, user IDs, computer IDs and application IDs. In the present invention, it is the policies that determine the way or method in which a user is to be authenticated by the system. The pre-defined polices include an OR policy, an AND policy, a CONTINGENT policy, a RANDOM policy and a THRESHOLD policy, a multi-user policy, a multi-location policy, a multi-template policy, a user dependent policy, a location restriction policy, and a computer/device specific policy.
