Abstract: A wireless electronic device (110) that executes the steps of: (a) receiving, from a plurality of electronic devices, a unique identifier associated with each electronic device; (b) identifying, from the plurality of electronic devices, at least one listening agent device (120); and (c) sending scan data to the listening agent device (120). The scan data includes the unique identifiers received from one or more of the plurality of electronic devices other than the listening agent device (120), and a unique tracking identifier associated with the wireless electronic device (110). The steps (a) to (c) are performed using a wireless communications protocol, such as Wi-Fi or Bluetooth. For Wi-Fi, the unique identifier is received in a first 802.11 management frame of a probe response; and the scan data is sent in a vendor-specific information element (VSIE) of a second 802.11 management frame of a probe request.

Abstract: Techniques for self-isolation of a network device that has been identified as potentially harmful. The network device may be isolated from the network except for an out-of-band communication channel that can be used for management purposes to restore or repair the device prior to the network connection being re-established.
