Abstract: Provided is a method for defending a DoS attack using a firewall of a vehicle network according to an embodiment of the present invention. The method includes: defining a rule according to an attack pattern checked in an application layer and generating a DoS attack rule based on the rule; checking that a packet is received and determining whether the DoS attack rule is activated; checking whether the packet matches the DoS attack rule when the DoS attack rule is activated; and transmitting the packet to a user space when the packet does not match the DoS attack rule. According to the present invention, at least one of an autonomous vehicle, a user terminal, and a server may be linked with an artificial intelligence module, a drone (unmanned aerial vehicle (UAV)), a robot, an augmented reality (AR) device, a virtual reality (VR) device, devices related to 5G services and the like.
