Each data acquisition requirement can be further refined into multi-level specific requirements, such as acquisition of vehicle codes, acquisition of user identification numbers and the like, and each requirement is identified through a corresponding request parameter. In a specific embodiment, the execution tool is configured with a collection requirement setting interface for acquiring the data collection requirement; the execution tool responds to the request parameters input by the user in the setting interface and transmits the request parameters to the controller. The request parameters may be request parameters for identifying four major requirements, i.e., basic information acquisition, application file acquisition, key certificate file reading, and mirror image copying, or may be request parameters for identifying specific requirements of each hierarchy.

Furthermore, each data acquisition requirement corresponds to at least one test case; each test case is logic for identifying a data file with sensitive information, and comprises a file type and sensitive information keywords of data acquisition requirements. Specifically, the file type may be represented as a file suffix, and the sensitive information keyword (e.g., "user name" or "id card") is used to locate the sensitive information.
In one embodiment, the test case library includes: the system comprises a mapping list of data acquisition requirements and file types and a corresponding keyword driving framework. The controller responds to a data acquisition requirement, and injects an information security test case corresponding to the data acquisition requirement into the execution tool, and the method comprises the following steps: the controller analyzes the data acquisition requirement and determines the file type corresponding to the data acquisition requirement through traversing a mapping list; and determining a sensitive information keyword corresponding to the data acquisition requirement according to the keyword driving frame, and injecting a test case comprising the file type and the sensitive information keyword into the execution tool. Furthermore, the controller is internally provided with automatic test case injection software, and the test cases are injected into the execution tool by running the software.
And S120, the execution tool identifies the data file with the sensitive information in the vehicle-mounted information interaction system to be detected according to the file type and the keywords, extracts the sensitive information and identifies the security vulnerability.
Firstly, the execution tool calls an operation environment and an operation script corresponding to the test case, and the operation script is operated in the operation environment to identify and collect a data file with sensitive information in the vehicle-mounted information interaction system to be tested. The running environment is a data acquisition environment, and the running script is used for converting the identification logic in the test case into an executable program language in the running environment. Optionally, the running environments corresponding to the test cases are consistent, the corresponding running scripts are different, and the running scripts are preset according to the test cases. And the execution tool faces different acquisition requirements and respectively starts corresponding running scripts.
In the execution process of the running script, an execution tool searches data information in a traversing mode of a thread pool, and identifies data files with sensitive information based on keywords and file types in a mapping list, wherein the data files comprise certificate key files, password files, system configuration files, log files, sensitive information files and the like; and operating a data acquisition program, and reading the data files through an interface with the test sample piece.

In one embodiment, the execution tool classifies sensitive information of the data file, such as identification number, license plate number, etc., according to the relevant information (such as keywords, etc.) related to the collected file type and file content. Taking the classification as the identification number as an example, the specific identification number of the data file is extracted according to the data rule (such as 18 decimal numbers) of the identification number. If the data recorded in the data file is matched with the data rule of the identity card number, namely 18 decimal numbers can be read, the identity card number is judged to be valid according to the matching of the first 6 decimal numbers with the data list of province-city, if the matching is successful, the test sample piece is indicated to be stored in the clear text, and the security vulnerability of the clear text storage of the identity card number exists. In addition, if the identity card number is not backed up and the access authority is too large, security holes in the aspects of backup and access authority exist at the same time.
After the security vulnerabilities are identified, the execution tool feeds back the security vulnerabilities, the related sensitive information and the data files in which the sensitive information is located to the controller.
And S130, the controller generates an information security test report according to the security vulnerability.
Optionally, the controller performs at least one of the following operations to circumvent the security breach: formulating a data acquisition rule, formulating a data transmission encryption rule, formulating a data encryption storage rule and setting a data access authority; and generating an information security test report according to at least one of the data acquisition rule, the data transmission encryption rule, the data encryption storage rule and the data access authority.
