Evaluating Detectability of Information in Authorization Policies

Номер: US20130031596A1
Автор: Moritz Becker

Techniques for evaluating detectablity of confidential information stored in authorization policies are described. In an example, an authorization policy has a confidential property. The confidential property is defined by whether application of a test probe to the authorization policy results in the grant of access to a resource. A processor automatically determines whether at least one witness policy can be generated that is observationally equivalent to the authorization policy from the perspective of a potential attacker, but the application of the test probe to the witness policy generates an access denial result. In the case that such a witness policy can be generated, an indication that the confidential property cannot be detected using the test probe is output. In the case that such a witness policy cannot be generated, an indication that the confidential property can be detected using the test probe is output.
