analyze the received traffic to detect at least one new active wireless connection between a legitimate wireless user device of the at least one wireless user device and at least one unknown wireless user device, wherein the legitimate wireless user device is at least legitimately authorized to access a protected computing resource of the organization;

determine if the detected at least one new active wireless connection forms a vulnerable wireless network based at least in part on whether the at least one new active wireless connection bridges between an internal network of the organization and an external resource, wherein the external resource is separate from the at least one unknown wireless user device and the legitimate wireless user device; and

initiate at least one mitigation action, upon determining that the detected at least one new active wireless connection forms the vulnerable wireless network.

13. The system of claim 12 , wherein the received traffic includes data extracted from a wireless protocol utilized for transmission by the at least one wireless user device.

14. The system of claim 13 , wherein the received traffic is intercepted by a plurality of sensors deployed in the wireless environment.

15. The system of claim 13 , wherein the received traffic includes at least one of: an indication regarding establishment of a new connection, an indication regarding existence of an active connection, a network address of any source, a destination user device participating in the detected at least one new active wireless connection, or payload data.

16. The system of claim 15 , wherein the at least one type of wireless protocol is any one of: Wi-Fi, nRF, long term evolution (LTE), third generation, Bluetooth, Wi-Gi, Zigbee, and Z-Wave.

17. The system of claim 12 , wherein an unknown wireless user device is a wireless user device not authorized to access the protected computing resource.

18. The system of claim 12 , wherein the system is further configured to:

perform at least one investigation action;

determine a risk factor based on each of the at least one investigation action;

compute a risk score based on the determined risk factor; and

19. The system of claim 18 , wherein the at least one investigation action is at least one of:

detecting at least one anomaly based on a usage pattern of the detected at least one new active wireless connection;

classifying a type of information transmitted over the detected at least one new active wireless connection; or

analyzing a fingerprint of the at least one unknown wireless user device.

20. The system of claim 12 , wherein the system is further configured to:

generate an alert, upon determining that the detected at least one new active wireless connection forms the vulnerable wireless network.
