The intelligent vehicle-road cooperation system realizes intelligent cooperation and fusion of people, vehicles and roads based on technical means such as advanced wireless communication and sensing detection, and provides great convenience for people's traveling. The intelligent vehicle-road cooperative system provides convenience for people, and simultaneously faces the challenge of information safety, and in order to ensure the information safety, various information safety tests are required in the research and development process. In the related technology, the intelligent vehicle-road cooperation system mainly comprises a vehicle-mounted terminal and a road side terminal of an intelligent networking automobile, and a client and a server of an intelligent networking application service, and due to the fact that terminal architectures, operating systems and application service types are various, unified information safety tests cannot be conducted, and testing efficiency is low.
In order to solve the above technical problem, the present application provides an information security testing scheme for an integrated intelligent vehicle-road coordination system, which is described in detail below by embodiments.
Examples
Referring to fig. 1, fig. 1 is a flowchart of an information security testing method of an intelligent vehicle-road coordination system according to an embodiment of the present disclosure.
As shown in fig. 1, the present embodiment provides an information security testing method for an intelligent vehicle-road coordination system, where an execution subject of the method may be an upper computer for testing or a functional module based on software and/or hardware therein, and the method at least includes the following steps:
and 11, determining the type of the current tested object according to the first input operation, wherein the type comprises a terminal class and an application service class.
In this step, objects to be subjected to security testing in the intelligent vehicle-road coordination system are classified into two types according to testing characteristics, one type is a terminal type, such as various vehicle-mounted terminals and road side terminals of an intelligent networked automobile, and the other type is an application service type, such as a positioning application service and various streaming media application services.
In a specific application scenario, after the upper computer is started, an operable interface can be provided, a type selection component is provided on the operable interface, and the type of the current measured object is determined according to a first input operation corresponding to the type selection component.
Step 12, according to a second input operation, obtaining a test file required by the current tested object in the current type from a pre-constructed file library; the file library stores test files of various tested objects of each type.
The specific content of the test file stored in the file library can be correspondingly set according to different types of test requirements so as to adapt to the test characteristics of the types.
For the terminal class, the test file of each tested object stored in the file library may include an execution file corresponding to a plurality of test items. The execution file contains logic code that implements the project test. In practical application, all test items to be performed by the tested object of the terminal class of the intelligent vehicle-road cooperative system can be collected in advance, then the logic code corresponding to each test item is compiled, an execution file is generated and stored in a file library, for example, the test items to be performed by a general vehicle-mounted terminal can include port scanning, vulnerability scanning, memory overflow attack and the like, taking port scanning as an example, the logic code capable of realizing port scanning can be compiled in advance, an execution file is generated and stored in a file library, and when a security test is performed, the test item can be scanned by the port as long as the execution file is obtained and operated. Accordingly, the specific implementation manner of this step 12 may be: selecting a test item required by the current tested object from the plurality of test items according to a second input operation; and acquiring the execution file corresponding to the selected test item from the file library. Because the file library has test files of a plurality of test items of a plurality of tested objects, no matter which terminal the tested object is, a user can select a required test item from the plurality of test items according to actual needs, for example, different test items can be selected for operating systems of different terminals, and then an execution file corresponding to the selected test item is obtained from the file library. In practical application, a selection component of the test item can be provided through the operable interface, and the selected test item is determined according to a second input operation corresponding to the selection component of the test item.
For the application service class, the test file of each tested object which can be stored in the file library comprises an application protocol format file; the application protocol format file stores the data protocol format of the application service. Similarly, the data protocol formats of the objects to be tested of the application services of all the intelligent vehicle-road coordination systems, such as the data protocol format for positioning the application service, the data protocol formats of various streaming media application services, and the like, may be collected in advance, and then the data protocol format of each application service is saved in the respective application protocol format file. Because the file library has application protocol format files of various application services, no matter which application service is tested, the corresponding application protocol format file can be obtained from the file library. In practical application, a selection component of the application service can be provided through the operable interface, the selected application service is determined according to a second input operation corresponding to the selection component of the application service, and then an application protocol format file corresponding to the selected application service is obtained from the file library.
And step 13, carrying out information safety test on the current tested object according to the obtained test file required by the current tested object.
If the current type is a terminal type and the test file is an execution file, the specific implementation manner of step 13 is to run the acquired execution file to perform information security test on the current object to be tested. Before the security test of the object to be tested, the object to be tested needs to be started, a security mechanism (such as a firewall) is started, and in the process of the information security test, after the current object to be tested detects the information attack, time, times and the like are recorded to generate a security log.
If the current type is the application service type and the test file is the application protocol format file, the specific implementation manner of step 13 is as follows: acquiring the data protocol format from a test file required by the current tested object; and generating and sending a data packet with aggressivity required by the client and/or the server corresponding to the current object to be tested through a network flow generator according to the acquired data protocol format. The attack type of the data packet can be selected and set according to the needs of the user, for example, the attack type can be information spoofing, information tampering and the like. Similarly, the security mechanisms of the client and the server corresponding to the current tested object respond to generate a security log.
In order to accurately price the information security status of the intelligent vehicle-road cooperative system, after the current tested object is tested according to the obtained test file required by the current tested object, a security log generated in the information security test process of the current tested object is obtained, security abnormal information recorded in the security log is obtained, the security abnormal information recorded in the security log is compared with preset simulated attack information, and a security test report is generated according to the comparison result. Therefore, the test result can be automatically analyzed and the test report can be generated, and the test efficiency is improved. When the safety test report is generated according to the comparison result, specifically, parameters such as response delay, intrusion recognition rate, false alarm rate and the like can be calculated according to the comparison result, and the test report is generated according to the calculation result, so that various analysis results are provided for people.
According to the scheme, the tested object needing information safety testing in the intelligent vehicle-road cooperative system is divided into two types, namely a terminal type and an application service type according to the difference between software and hardware, various testing files of the tested object are stored in a file library in advance for each type, the testing files needed by the current tested object can be obtained from the file library only through simple input operation, and the current tested object is subjected to information safety testing.
