摘要： A wireless access point and a method may be provided for detecting a malicious device in a network. The wireless access point may include a controller, a search unit, a message generation unit, and a determination unit. The controller may be configured to initiate a malicious device detection mode regularly at predefined intervals. The search unit may be configured to detect candidate devices broadcasting a signal with the first SSID from neighbor devices in an associated network. The message generation unit may be configured to generate a test message in the malicious device detection mode and transmit the test message to the candidate devices. The determination unit may be configured to determine a corresponding device in the candidate device as a malicious device when a test response message is not received from the corresponding device in response to the test message.
