摘要

Disclosed herein are an apparatus and method for transmitting fuzzing data. The apparatus may include one or more processors and executable memory for storing at least one program executed by the one or more processors. The at least one program may collect context information pertaining to a one-way fuzzing target device that uses a one-way protocol, may determine the execution state of the one-way fuzzing target device by analyzing the context information, and may transmit fuzzing data to the one-way fuzzing target device based on the result of determination of the execution state.

說明書

That is, at step S220, the transmission rate of fuzzing data may be set.

Here, at step S220, the transmission rate of the fuzzing data may be set based on the CPU usage of the one-way-fuzzing-target-processing unit 11 and the CPU usage of the network task.

Referring to FIG. 4, at step S220, first, the CPU usage may be collected at step S221.

That is, at step S221, the CPU usage of the one-way fuzzing target and the CPU usage of the network task of the one-way fuzzing target may be collected.

Also, at step S220, the CPU usage of the network task may be compared at step S222.

That is, at step S222, the current CPU usage of the network task of the one-way fuzzing target may be compared with the previous CPU usage thereof.

Also, at step S220, whether the current CPU usage is equal to the previous CPU usage may be checked at step S223.

That is, when it is determined at step S223 that the current CPU usage of the network task of the one-way fuzzing target is equal to the previous CPU usage thereof, the transmission rate of fuzzing data may be decreased at step S226. When the current CPU usage of the network task of the one-way fuzzing target is not equal to the previous CPU usage thereof, the CPU usage of the one-way fuzzing target may be compared at step S224.

That is, at step S224, the current CPU usage of the one-way fuzzing target may be compared with the previous CPU usage thereof.

Also, at step S220, whether the current CPU usage is equal to the previous CPU usage may be determined at step S225.
