Abstract:
A security apparatus is provided that is connected to a bus. The security apparatus includes a receiver that receives a first frame from the bus, a memory that stores an examination parameter defining a content of an examination on the first frame, and processing circuitry that performs operations. The performed operations include first determining whether a predetermined condition is satisfied for the first frame. The performed operations also include, in a case where the first determining determined that the predetermined condition is satisfied, updating the examination parameter stored in the memory. The performed operations further include second determining whether the first frame is an attack frame based on the updated examination parameter stored in the memory.

Claim (Index 2):
The security apparatus according to  claim 1 , wherein\n the first frame is a data frame including an ID field storing an ID, Data Length Code (DLC), and a data field, the examination parameter stored in the memory includes a threshold value indicating an upper limit of an allowable range of a frequency of transmission of one or more frames whose ID values are identical within a predetermined unit time, the first determining determines that the predetermined condition is satisfied for the first frame received by the receiver, in a case where a transmission interval is out of a predetermined allowable range, the transmission interval being defined by a reception interval between the first frame and a second frame whose ID value is identical to the ID value of the first frame, the updating updates the threshold value, in a case where the first determining determined that the predetermined condition is satisfied, and the second determining determines that the first frame received by the receiver is an attack frame, in a case where the frequency of transmission of the first frame received by the receiver is higher than the updated threshold value.
