Abstract: A principal is authenticated for access to a resource and assigned access rights for an authenticated session with the resource. Activity of the principal is monitored during the session, analyzed in real-time, and assigned a security score. Actions of the principal can be denied based on comparison of the score to a threshold; the session can be terminated; a policy can be set to disconnect the principal from future authenticated sessions with the resource once the principal connects with the resource; and/or the action is denied but the principal is permitted to continue with the authenticated session with the resource. No changes are made to the principal's access rights assigned for the authenticated session.
