Abstract
Techniques are described to detect and/or prevent malicious wireless attacks and/or suspicious wireless activity related to a wireless network in a commercial passenger vehicle. For example, an access point located in the commercial passenger vehicle receives a set of wireless beacon frames from a first wireless device, makes a first determination of a first beacon frame rate of the set of wireless beacon frames, receives a second beacon frame after a first beacon frame, makes a second determination of a second beacon frame rate of the second beacon frame relative to the first beacon frame, makes a third determination that a second wireless device is impersonating the first wireless device upon comparing the first beacon frame rate to the second beacon frame rate, and sends, upon making the third determination, a security alert message to an external input/output (I/O) device in the commercial passenger vehicle.
