<p>An abnormal message detecting and processing apparatus comprises an example message storing part (30) for storing examples of normal messages, a variable field information storing part (32) for storing information of a location of variable fields in the example messages, and an abnormal message detecting part (34). The abnormal message detecting part (34) compares input messages (36) with the example messages, except for variable fields specified by the information stored in the variable field information storing part (32), determines that an input message is abnormal if none of the example messages coincide with the input message in the comparison, and outputs the message so that the abnormal message is easily distinguishable from normal messages. <IMAGE></p> |
