A system and a method for limiting the reception of ethernet traffic for CPU security are provided to prevent the overload of a system and increase the stability of processors by limiting the volume of receiving packets per second and regulating the volume of packets received to processors. An ethernet controller comprises a central processing part, a received packet processing part, and an interrupt processing routine part. The central processing part establishes a reference value for the volume of packets to receive, and generates an Rx interrupt when packets are received. The received packet processing part checks whether packets are supplied in excess of the established volume. If packets are supplied in excess of the established volume, the received packet processing part notifies the interrupt processing routine part of it. The interrupt processing routine part, notified that packets are supplied in excess of the established volume, inactivates the generation of Rx interrupts.
