Abstract: A method of identifying a malicious AP by a terminal apparatus includes obtaining first performance information related to hardware of a first AP based on a first beacon signal received from the first AP, comparing the first performance information with previously stored second performance information of a second AP, and determining whether the first AP is a malicious AP, based on a result of the comparing.

Abstract: An electronic device is provided. The electronic device includes a display, a communication circuit, a sensor, and a processor, wherein the processor is configured to identify, through the communication circuit, data packet information associated with an external electronic device, identify a first external electronic device from among the external electronic device based on the data packet information, obtain a predicted frame (P-frame) pattern during a first time period and a P-frame or received signal strength indication (RSSI) pattern during a second time period based on information associated with the packet size of the first external electronic device in the data packet information, identify a motion vector during the second time period through the based sensor, and provide position information about the first external electronic device based on the P-frame or RSSI pattern during the second time period and the motion vector during the second time period.

Abstract: A method of identifying a malicious access point (AP) by a terminal apparatus includes obtaining first performance information related to hardware of a first AP based on a first beacon signal received from the first AP, comparing the first performance information with previously stored second performance information of a second AP, and determining whether the first AP is a malicious AP, based on a result of the comparing.
