PROBLEM TO BE SOLVED: To provide an electronic equipment device capable of speedily dealing with a network attack, by reducing the burden of a manager, and eliminating the need for the manager to manually delete objects to prohibit communication on a communication inhibition list. SOLUTION: The electronic equipment device comprises an attack detection unit for detecting a communication attack over a network; a communication management unit which manages communication with the network and defines a communication target which performs communication attack, as an object to inhibit communication, when the attack detection unit detects the communication attack; and a security management unit which manages communication inhibition information that is information about the object to inhibit communication, and is mainly characterized in that the security management unit records the communication inhibition information, while adding validity thereto, and the communication management unit inhibits communication with that object to inhibit communication, based on the communication inhibition information and recovers communication with the object to inhibit communication, after the validity has expired.
