PROBLEM TO BE SOLVED: To provide a technique for properly defending a communication apparatus against an attack. SOLUTION: A communication control apparatus 10 includes: a database storing reference data for determining communication data used to attack the communication apparatus; a searching circuit for acquiring the communication data and searching whether the reference data stored in the database are included in the communication data; and a processing execution circuit for filtering the communication data when the communication data including the reference data is transmitted to a specific communication apparatus at the predetermined times or more. A PHY processing section 5a omits processing for confirming whether the address of a destination is the address of its own apparatus, and supplies the acquired communication data to the searching circuit.
