Publication number: 20240121244Abstract: A risk-aware access control system and related methods are provided. In accordance with one aspect of the present disclosure, there is a provided a method of risk-aware access control, comprising: detecting a request to perform an action with respect to two factors, the factors being of a factor type selecting people, devices, documents, and location, wherein the factors are of a different factor type; determining a coupling associated with the requested action based on the factors of the requested action; determining a risk level associated with the coupling; denying the requested action in response to a determination that the risk level does not match a security policy; and allowing the requested action in response to a determination that the risk level matches the security policy.Type: ApplicationFiled: December 6, 2023Publication date: April 11, 2024Inventors: Andrew James Malton, Andrew Eric WALENSTEIN, Jinxin Liu, Burak KANTARCI, Melike EROL KANTARCI, Murat Simsek

Patent number: 11886563Abstract: A continuous authentication system and related methods are provided. The system detects requests to perform user actions. A security value is associated with each user action. The system determines a subsequent session security level in response to an adjustment to a session security level by a security value of a requested user action. The requested user action is permitted and the session security level is adjusted based on the security value of the requested user action in response to a determination by the system that the subsequent session security level is greater than or equal to a threshold session security level. A user authentication challenge is caused (e.g., prompted) in response to a determination by the system that the subsequent session security level is less than the threshold session security level.Type: GrantFiled: February 14, 2023Date of Patent: January 30, 2024Assignee: BlackBerry LimitedInventors: Andrew James Malton, Andrew Eric Walenstein
