[0045] It should be noted that various aspects of the embodiments described below are within the scope of the appended claims. It should be apparent that the aspects described herein can be embodied in a wide variety of forms and that any specific structure and / or function described herein is merely illustrative. Based on the teachings herein one skilled in the art should appreciate that an aspect described herein can be implemented independently of any other aspects and that an aspect can be implemented both as any number of software and / or hardware structures. For example, an aspect can be implemented as a single structure or any number of separate structures or instances, operating together or independently of one another.

[0046] Reference will now be made to Figure 1 As shown in the figure, according to an aspect of the present application, a device behavior simulation method is provided, which is applied to a hardware chip used for simulating the working behavior of a target device.

[0047] The method comprises the following steps:

[0048] In step S100, an environment parameter and a running file corresponding to the target device are acquired.

[0049] In step S200, a running environment is established in the hardware chip according to the environment parameter.

[0050] In step S300, the running file is executed in the running environment, so that the hardware chip simulates the working behavior of the target device.

[0051] In the hardware chip, a firewall is arranged, and the firewall is provided with a target vulnerability.

[0052] In the embodiment, the target device is an industrial internet device, such as a PLC, an embedded controller or a single-chip microcomputer, etc.

[0053] In the traditional behavior simulation mode, if the PLC behavior is simulated, since the PC is used to only perform the communication simulation at the software level, it belongs to the low-interactive behavior simulation, and the probability of being recognized by a malicious user is high. The high-interactive behavior simulation needs to use the same device as the simulated device to perform simulation running, but since the cost of a single device is often high, the cost of this behavior simulation mode is very high.

[0054] In the embodiment, the hardware chip itself is a programmable and logic processing hardware chip, and also has a plurality of data interaction interfaces, and can realize the interface simulation and actual running behavior simulation of the PLC and other industrial internet devices. Therefore, a running environment same as the target device can be actually established in the hardware chip, and the running is stable in the running environment, and the actual running is realized, so that the high-interactive behavior simulation is realized. That is, the running environment and running action (execution of running file) of the hardware chip and the target device are kept the same, and no behavior or data is generated by software simulation, so that the deception to malicious users is strong when implemented.

[0055] Meanwhile, the target vulnerability is set in the firewall in the hardware chip, and the target vulnerability is used to lure malicious users to attack, so that the hardware chip can capture and monitor the attack behavior of the malicious users through the target vulnerability under control.

[0056] The device behavior simulation method provided in the embodiment can establish the same running environment as the target device in the hardware chip through the environment parameters and the running file of the target device, and run the running file of the target device in the running environment, to realize the working behavior simulation of the target device. In the embodiment, the working behavior of the target device is directly simulated by the hardware chip, so that the working behavior of the target device is actually run in the hardware chip, instead of being virtually run by software, so that the concealment of the hardware chip is improved, and it is not easy to be recognized by malicious users, and the security is improved. And the cost of a single hardware chip is lower than that of the target device, so that the low-cost high-interactive behavior simulation is realized.

[0057] In an example embodiment of the present application, the running environment is established in the hardware chip according to the environment parameters, comprising:

[0058] determining at least one original data exchange interface of the target device according to the environment parameters;

[0059] determining the target data exchange interface corresponding to each original data exchange interface, the target data exchange interface being a physical interface of the hardware chip;

[0060] configuring the target data exchange interface, so that the target data exchange interface can perform the same function as the corresponding original data exchange interface.

[0061] Both the original data exchange interface and the target data exchange interface can be I / O interfaces. Specifically, configuring the target data exchange interface involves configuring it according to the interface name, corresponding functions, and connection relationships of the original data exchange interface, so that the target data exchange interface has the same configuration as the original data exchange interface and performs the same functions.

[0062] In this embodiment, when establishing the operating environment, unlike the software behavior simulation method which uses a simulated data interface (without an actual interface, only a virtual address), the physical interface of the hardware chip is used to perform the same work as the target device's response data exchange interface. This realizes the actual operation of the interface function, so it is difficult for malicious users to identify that the interface is not the actual data exchange interface in the industrial Internet device through the behavior and related data of the target data exchange interface, further improving the concealment of the device behavior simulation method.

[0063] In one exemplary embodiment of this application, the target device has an upstream device and a downstream device communicatively connected to it;

[0064] The hardware chip is connected to the upstream device and the downstream device;

[0065] The hardware chip can receive input information sent by the upstream device and process the input information according to the running file to obtain output information;

[0066] The output information is used to send to the downstream device, and the output information is configured not to be responded to by the downstream device.

[0067] In this embodiment, the hardware chip is actually connected to the upstream and downstream devices corresponding to the target device, and also receives input information from the upstream device and sends output information to the downstream device. Thus, from the perspective of a malicious user, the hardware chip appears to be actually connected to the industrial internet network and performing inter-device communication.

[0068] Meanwhile, the hardware chip uses the same runtime file as the target device to process the input information, and it also performs actual processing on the input information. Unlike software simulations that directly determine the output information through simple mapping tables, the hardware chip's simulation behavior appears identical to that of the target device from the perspective of a malicious user. This further enhances the hardware chip's stealth and makes it difficult for malicious users to detect.

[0069] Specifically, in the embodiment, the hardware chip can be seen as parallel to the target device to some extent, and the input information obtained and the output information generated by the two are the same in information path and information content. However, the output information of the hardware chip will not be responded by the downstream device connected thereto, so as to avoid the case that the output information is changed by a malicious user after the target vulnerability is intruded, thereby affecting the normal work of the downstream device.

[0070] The implementation method of configuring the output information not to be responded by the downstream device can be that a setting identifier or character is embedded at a setting byte of the output information of the hardware chip, so that the downstream device directly discards the information after receiving the information with the setting identifier or character. Or the I / O port connecting the downstream device and the target chip is directly set as a null port.

[0071] In an exemplary embodiment of the present application, the running environment includes an operating system.

[0072] The method further includes:

[0073] determining a memory address set corresponding to the operating system;

[0074] directly accessing the physical memory relied on by the operating system according to the memory address set, to obtain running information of the operating system.

[0075] In some high-end industrial internet devices, there is an operating system inside to run some software programs and the like. However, since the operating system of the industrial internet device is mostly a closed system, the internal behavior data cannot be obtained through a proxy mode when the actual industrial internet device is used to simulate high-interaction behaviors, so the collected data is limited.

[0076] The hardware information provided in the embodiment also establishes a corresponding operating system when establishing a running environment, directly accesses the physical memory (hardware memory) relied on by the operating system during the running of the operating system according to a memory address set corresponding to the operating system in the working environment (DMA, Direct Memory Access), to directly read the related data in the running process of the operating system, and to determine the attack behavior of a malicious user by analyzing the read system memory data (running information). For example, by reading the network card traffic data, all communication data in the network card are recorded. The collected data can include host keyboard input, network communication port, system log, host file change, network communication data packet, device running state and remote operation log, so as to covertly record the keyboard input, communication port, log, file change, network communication and the like of the attacker.

[0077] Compared with reading through a Hook system API, the embodiment realizes traceless behavior data collection, increases the concealment of device behavior simulation, and improves the comprehensiveness of collected data.

[0078] In an example embodiment of the present application, the method further comprises:

[0079] determining abnormal data in the running information;

[0080] According to the data source corresponding to the abnormal data, the data sent by the data source is continuously monitored.

[0081] Specifically, the receiving information and the output information of the intelligent device in the industrial internet are relatively single, and the information structure and content are relatively unified, so that the method for determining abnormal data in the running information can be that each input information and output information in the running information is compared with a normal information template, so that the information with greater difference is determined as abnormal data. The abnormal data can also be determined by comparing the function and security function corresponding to each running information.

[0082] After the abnormal data is determined, the corresponding data source (malicious user) can be determined according to the data source information corresponding to the abnormal data. Thus, the data source is directly monitored to realize targeted attack behavior data acquisition and monitoring.

[0083] In an example embodiment of the present application, a firewall is arranged in the hardware chip, the firewall is provided with a target vulnerability, and the target vulnerability has a corresponding calling interface;

[0084] The method further comprises:

[0085] The data packet received by the calling interface is captured.

[0086] Since the target vulnerability is set purposefully, the probability of attack by the malicious user through the calling interface corresponding to the target vulnerability is relatively large, so the calling interface can be directly monitored and the data packet can be captured purposefully. The capture method can be that the calling interface is set to send each data packet to an analysis module in the hardware chip in addition to normal processing such as sending and forwarding, so that the analysis module can analyze the content of the data packet and discover the attack of the malicious user in time.

[0087] In an example embodiment of the present application, the method further comprises:

[0088] A reset instruction is received to reset the running environment.

[0089] The resetting of the running environment refers to restoring the running environment to an initial establishment time of the running environment, that is, the running environment established according to the environment parameter just after the establishment.

[0090] In the conventional method, the target device is simulated by the same actual device, and after the actual device is attacked, if the actual device is reset, the resetting can only be performed by restoring the factory settings, but the resetting in this way also causes the running environment and the executable file set according to the target device in the device to be restored and deleted, and thus a large amount of operations are required to set the related parameters and the like after the resetting.

[0091] The device behavior simulation method provided in this embodiment can periodically acquire attack source identification data and attack process record data of a behavior simulation chip (hardware chip), and determine whether the cyberspace deception system is attacked. When it is found that the hardware chip is attacked, an alarm is given and a record is made. Moreover, the hardware chip that is attacked can be quickly reset to the state before the attack, and the hacker attack is induced again to capture the attack weapon and analyze the attack process, attack means, attack technology and the like. Compared with the behavior simulation using the actual device, the resetting speed is fast and no additional operation cost is required.

[0092] Please refer to Figure 2 According to an aspect of the present application, a device behavior simulation apparatus is provided, which is applied to a hardware chip and used for simulating working behavior of a target device.

[0093] The apparatus comprises:

[0094] An acquisition module is configured to acquire environment parameters and running files corresponding to the target device.

[0095] An establishment module is configured to establish a running environment in the hardware chip according to the environment parameters.

[0096] A running module is configured to execute the running files in the running environment, so that the hardware chip simulates the working behavior of the target device.

[0097] The hardware chip is provided with a firewall, and the firewall is provided with a target vulnerability.
