Abstract

The present invention is directed to systems and methods for automated detection of one or more wireless network policy violations and/or enforcement of such policies. A wireless network policy violation is detected. Associated with the detected violation are one or more wireless network attributes. A responsive corrective action is triggered which is based at least in part upon the detected violation, the associated wireless network attributes or combinations thereof. The corrective action can in some instances include a notification to a user or further system. In addition to, or instead of, a notification, the corrective action can include an attempt to configure one or more devices in the wireless network to correct, in whole or in part, the detected violation.

5. The system of claim 4, and further comprising c) an interface allowing communication between the system processor and a device associated with the detected violation and wherein the programming or adaptation to trigger a corrective action comprises programming or adaptation to:

(1) establish a communication channel with a device associated with the detected violation via the interface; and

(2) transmit instructions via the communication channel to configure one or more properties of the device, wherein the one or more properties are associated with a subset of one or more attributes in the set of wireless network attributes associated with the violation detected and wherein the instructions are based upon configuration data in the SDS associated with the subset of one or more attributes.

6. The system of claim 1, wherein the programming or adaptation to trigger a corrective action comprises programming or adaptation to transmit a communication to a monitoring system or to a user.

7. The system of claim 6, wherein the programming or adaptation to trigger a corrective action further comprises programming or adaptation to prepare a communication for transmission to a monitoring system.

8. The system of claim 7, wherein the programming or adaptation to prepare a communication comprises programming or adaptation to embed in the communication information associated with the violation detected.

9. The system of claim 8, wherein the information associated with the violation detected comprises an indicator of the violation detected, one or more indicators corresponding to attributes in the set associated with the violation detected, or one or more indicators corresponding to configuration data associated with one or more attributes in the set associated with the violation detected.

10. The system of claim 8, wherein the programming or adaptation to prepare a communication comprises further programming or adaptation to embed in the communication instructions that will cause the monitoring system to configure one or more devices in the wireless network based upon the information associated with the violation detected also embedded in the communication.

11. The system of claim 7, wherein the programming or adaptation to prepare a communication comprises programming or adaptation to embed instruction in the communication that will cause the monitoring system to log the violation detected.

12. The system of claim 6, and further comprising c) an interface allowing communication between the system processor and a device associated with the detected violation and wherein the programming or adaptation to trigger a corrective action comprises further programming or adaptation to establish a communication channel with the device via the interface and to transmit instructions via the communication channel to configure one or more properties of the device, wherein the one or more properties are associated with a subset of one or more attributes in the set of wireless network attributes associated with the violation detected and wherein the instructions are based upon configuration data in the SDS associated with the subset of one or more attributes.

13. The system of claim 6, wherein the programming or adaptation to trigger a corrective action further comprises programming or adaptation to prepare a communication that comprises information associated with the violation detected for transmission to a user.
