Description

Dynamic test method and system of software using image cloning {METHOD AND SYSTEM FOR DYNAMIC TEST OF SORTWARE USING IMAGE DUPLICATION}

The disclosed technique relates to a dynamic test method and system of software using image replication.

 In the testing phase of software, it is often impossible to test only by static analysis that reads and interprets the code. In this case, a dynamic analysis of the software is performed, where the developer or security professional observes or compares the behavior while executing the software. In order to run a dynamic analysis, there must be a continuous input to derive the behavior to be analyzed. In addition, when reaching the point where the movement to be analyzed occurs, it is necessary to observe the various movements by supplying various inputs. In order to reach an operation to be observed, the user must enter a state in which an operation to be observed can occur by providing inputs of various levels based on information about the software.

When the software enters a state where an action to be observed can occur, the action must be observed in various ways by injecting various inputs. In order to observe various operations by injecting various inputs into the software, an important problem arises that once an operation on one input is executed, the next input cannot be injected. In other words, the image that can be observed by the execution of the software is changed so that the execution no longer exists in memory that can cause the desired operation. Therefore, in order to continue injecting various inputs for various observations of the software operation, it is necessary to return to the state where the operation to be observed can occur, and while the software is executed from the beginning, a continuous input for inducing a desired operation is required. It must be injected again. However, if the process of repeating the process of reaching again to the state where the operation to be observed can occur for a sufficient observation, it may cause a lot of time.

The technical problem of the disclosed technology is to perform a dynamic test of software through three main memories to reduce time consumption and increase efficiency.

According to a second aspect of the disclosed technology to achieve the above technical problem, a dynamic test method of software, the method comprising: (a) copying an image capable of observing the operation of the software from the first memory to the second memory; (b) operation observation is performed based on the image stored in the second memory, and the image stored in the first memory is duplicated into the third memory; And (c) operation observation is performed based on the image stored in the third memory, and the image stored in the first memory is copied to the second memory.

The disclosed technique may have the following effects. It is to be understood, however, that the scope of the disclosed technology is not to be construed as limited thereby, as it is not meant to imply that a particular embodiment should include all of the following effects or only the following effects.

The first to third memories 110, 120, and 130 are provided to replace the main memory in order to quickly restore the software to an image that can observe the operation of the software. For example, the first memory 110 may be viewed as an original memory, the second memory 120 may be a memory for which dynamic testing has been performed, and the third memory 130 may be regarded as a memory for which dynamic testing is to be performed.

Replicate to 120. Here, the motion observable image 400 is a memory image of a state in which a motion to be observed by the software may occur in a dynamic test of the software, and may be displayed by providing inputs of various levels based on information about the software. have. While the operation observation of the software is performed in the first memory 110, the second memory 120 duplicates the image 400 capable of observing the operation stored in the second memory 120 to the third memory 130. While the operation observation of the software is performed in the second memory 120, the third memory 130 copies the image 400 capable of observing the operation stored in the third memory 130 to the first memory 110. When the operation observation is terminated in the first memory 110, the operation observation may be performed in the second memory 120. While the operation observation of the software is performed in the third memory 120, the first memory 110 copies the image 400 capable of observing the operation stored in the first memory 110 to the second memory 120. When the operation observation is finished in the second memory 120, the operation observation may be performed in the third memory 130. The first memory 110 to the third memory 130 may repeat the above steps, and a developer or a security expert may observe the operation in each memory. By rapidly replacing the main memory and being able to quickly receive an image 400 capable of observing motion, dynamic testing of the software may be performed without executing the software again from the beginning.

3 is a flowchart illustrating a dynamic test method of software according to an embodiment of the disclosed technology. Referring to FIG. 3, software is executed in the first memory 110 to reach the image 400 in which the first memory 110 can observe the operation (S510). Here, software refers to software for performing dynamic tests to verify integrity. The motion observable image 400 is a memory image of a state in which motion to be observed in a dynamic test of software may occur, and may be displayed by providing inputs of various levels based on information about the software.

An image 400 capable of observing the operation of the software is copied from the first memory 110 to the second memory 120 (S520). The process of copying the image 400 capable of dynamically observing from the first memory 110 to the second memory 120 may be performed by the second processor 220. The process of duplicating the dynamic viewable image 400 is to prevent the main memory from being consumed a lot of time by speeding up the restoration of the main memory to the dynamic viewable image 400.

Operation observation is performed based on the image 400 capable of observing motion stored in the first memory 110, and the image 400 capable of observing motion stored in the second memory 120 is copied to the third memory 130. (S530).

The devices 300 may include a keyboard, a monitor, a network card, and the like. Replicating the image 400 in which the second memory 120 can observe the motion to the third memory 130 during the dynamic test of the software in the first memory 110 is to restore the image 400 in which the motion can be observed. To speed it up.

Operation observation is performed based on the image 400 capable of observing motion stored in the second memory 120, and the image 400 capable of observing motion stored in the third memory 130 is copied to the first memory (S540). ). More specifically, the operation observation in the second memory 120 is performed by the first processor 210, and the image 400 capable of observing the operation from the third memory 130 to the first memory 110 is provided. The copying may be performed by the second processor 220. When the operation is observed in the second memory 120, the devices 300 may be connected to the second memory 120.

As an example, the operation observation of the third memory 130 may be performed after the operation observation in the second memory 120 ends.

After the steps S510 to S550 are performed, the steps S530 to S550 may be repeated sequentially, and a developer or a security expert may observe an operation in each memory. The first to third memories 110, 120, and 130 may correspond to a main memory having the same specification. This is because three tests of the dynamic test, which were previously performed in one main memory, are performed in turn, and the dynamic test should be performed under the same conditions. In addition, the first to third memories 110, 120, and 130 may be provided to replace the main memory in order to quickly restore the software to an image that can observe the operation of the software. Therefore, the main memory can be quickly replaced and the image 400 capable of observing motion can be quickly supplied, thereby enabling dynamic testing of the software without executing the software from the beginning. The devices 300 connected to the first to third memories 110, 120, and 130 while the operation is being observed may be the same.
