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.

Terminal device and method for identifying malicious AP by using same

An electronic apparatus and control method thereof are provided. The electronic apparatus includes a sensor, a communicator, and a processor configured to, based on a wireless communication between a relay device and a terminal device being sensed by the sensor, identifies whether the relay device and the terminal device is an authorized device, and based on at least one of the relay device or the terminal device being identified as an unauthorized device, controls the communicator to transmit a beacon signal including communication channel transfer information to the terminal device.

Electronic apparatus and controlling method thereof

A server is provided. The server includes a communication interface configured to communicate with an electronic apparatus connected to an Internet of things (IoT) device, a storage configured to store a scenario about an attack received by the IoT device from an external apparatus by stages and information relating to a malicious code corresponding to the scenario, and a processor configured to, based on the IoT device being attacked by the external apparatus over at least one step through the electronic apparatus, receive, from the electronic apparatus, an alert for an attack received by stages, and to identify information relating to a malicious code corresponding to at least one alert received from the electronic apparatus based on the pre-stored scenario.

Server and method for defending malicious code using same

The present disclosure relates to a method for blocking the connection of an electronic device inside a wireless intrusion prevention system, the method comprising the steps of: successively monitoring wireless frames in a plurality of channels through a first communication module; generating a first blocking message on the basis of at least one wireless frame received as a result of the monitoring and generating a second blocking message on the basis of a first wireless frame, to which a predetermined wireless network technology has been applied, among the at least one wireless frame; and transmitting at least one of the first and second blocking messages through a second communication module. The present disclosure is not limited to the above embodiment, and other embodiments are also possible.
