Abstract:
1. A method of controlling access message flow comprising: upon receiving a particular access message at an access control server, determining a particular set of one or more features of the particular access message; determining whether the particular access message satisfies a particular condition based on the particular set of one or more features, wherein satisfying the particular condition indicates that the particular access message (a) has a valid format, and (b) comprises content that conflicts with a set of configuration information; and upon determining that the particular access message satisfies the particular condition, performing a responsive action based on the particular condition; wherein the set of configuration information identifies a feature to be detected in the particular set of one or more features, and wherein satisfying the particular condition comprises detection of the feature; wherein the particular set of one or more features is contained in the particular access message at the access control server; receiving a second access message, wherein a particular feature, of the particular set of one or more features of the particular access message, corresponds to a particular feature instantiation of the particular feature; wherein a second particular feature, of a second particular access message of the one or more access messages, is the same feature as the particular feature and the second particular feature corresponds to the particular feature instantiation of the particular feature; and wherein determining whether the particular access message satisfies the particular condition comprises determining if the difference in time between when the particular access message and the second oarticular access message arrived is less than a predefined threshold.
