Therefore, detecting the vulnerability of the intelligent terminal equipment is an important method for knowing the security of the intelligent terminal equipment and an important means for finding problems and timely repairing and defending vulnerability attacks.
The existing vulnerability detection method of the intelligent terminal device is used for detecting the vulnerability by installing and operating a detection program APP. A typical representative example is an Android VTS (Android Test Suite), which is an APP application of an Android system platform, and a user can install and run the APP to detect whether there are vulnerabilities on their intelligent terminal device, and can detect dozens of vulnerabilities on the intelligent terminal device. In addition, some existing vulnerability detection methods for intelligent terminal equipment of the Android operating system are installed in an apk (Android package) application mode.
The existing vulnerability detection method of the intelligent terminal equipment has the following defects:
1. the existing vulnerability detection method of the intelligent terminal equipment detects the version number and the update date of the current intelligent terminal system and components, and judges which vulnerabilities exist according to the version number and the update date, namely the patch date. The method has the defects that whether the loopholes exist or not is not actually detected, and the situation that whether a developer only modifies the version number and the updating date or not and the loopholes are not repaired cannot be dealt with; meanwhile, the situation that the developer only repairs the bugs and does not update the version numbers and the update dates cannot be dealt with.
2. When the application program installed by the APK is operated to carry out vulnerability detection on the intelligent terminal equipment, because the interfaces and the permission which can be accessed in the Android system are limited, the comprehensive vulnerability detection can not be carried out on the operating system and the components of the intelligent terminal equipment, and only the interfaces of the system files which can be contacted by the common application can be detected. The detection range of the existing vulnerability detection method is limited, and a single APP application cannot detect the vulnerability which can be triggered only when the terminal equipment is in communication interaction with other equipment through a Bluetooth module and a wifi module.
3. The intelligent terminal supporting detection in the prior art has singleness, the intelligent terminal to be detected in the prior art can only be an intelligent terminal, or can only be an intelligent watch, or can only be an intelligent navigation terminal, and no method can simultaneously and compatibly support detection of various intelligent terminal devices.

The information of the detection item includes: type information and version information. The vulnerability influence scope information comprises: vulnerability impact type range information and vulnerability impact version range information.
In one embodiment, the step S102 of writing a test case set for triggering the vulnerability according to the behavior characteristics of the vulnerability and the vulnerability influence range information includes:
and correspondingly compiling a test case set for triggering the vulnerability according to the known behavior characteristics and vulnerability influence range information of each vulnerability when the vulnerability occurs. Each vulnerability can have one or more behavior characteristics, at least one test case capable of triggering the corresponding vulnerability is compiled according to the behavior characteristics, a corresponding test case set is formed by the at least one test case, and the test case set is used for triggering the corresponding vulnerability.
During specific implementation, a test case set applying for an overflowing target buffer area A and an adjacent detection variable B is compiled according to behavior characteristic buffer area overflow, vulnerability influence type range information and vulnerability influence version range information. And after the test case set is executed, directly outputting the variable B or checking the content of the variable B in a debugger and other modes, if the content is changed, indicating that the detected intelligent terminal has a corresponding bug, otherwise, indicating that the detected intelligent terminal does not have the bug.
And writing a test case set with the illegally tampered data position in a controllable range according to the illegal tampering of the behavior characteristic data, the vulnerability influence type range information and the vulnerability influence version range information.

And after the test case set is executed, judging whether sensitive data can be output, if so, indicating that the detected intelligent terminal has a corresponding bug, otherwise, not judging that the detected intelligent terminal has the bug.
According to the behavioral characteristic program execution flow abnormity, the vulnerability influence type range information and the vulnerability influence version range information, a test case set which causes the program execution flow to be abnormal according to the vulnerability is compiled, and an observation point is set in the abnormal execution flow. And after the test case set is executed, judging whether the observation program running at the observation point accords with the vulnerability characteristics, if so, indicating that the detected intelligent terminal has a corresponding vulnerability, otherwise, not.

And after the test case set is executed, judging whether the output result of the test case set is matched with the program running result with the bug, if so, indicating that the detected intelligent terminal has the corresponding bug, otherwise, not.
In one embodiment, as shown in fig. 3, the step S104 of determining whether the information of each detection item matches the vulnerability influence range information of the test case set to be executed includes:
s301: and judging whether the type information of each detection item is matched with the vulnerability influence type range information of the test case set to be executed.
In specific implementation, after the type information of each detection item is read, whether the type information of each detection item is matched with the vulnerability influence type range information of the currently executed test case set is respectively judged. If the type information of the detection item does not belong to the range of the vulnerability influence type range information of the currently executed test case set, the type information is considered not to be matched; otherwise, a match is considered. Wherein the matching case comprises: the type information of the detection item belongs to vulnerability influence type range information of the currently executed test case set, and the detection item has no type information, and the like, which is not limited by the invention. The case of mismatch is: and detecting the type information of the item, wherein the type information of the item is not in the vulnerability influence type range information of the currently executed test case set. For example, the vulnerability influence type range information of the currently executed test case set is of an Android or IOS type, and when the type information of the detection item is Symbian, the vulnerability influence type range is not of the Android or IOS type and belongs to a mismatch condition; when the type information of the detection item is Android, the detection item belongs to a vulnerability influence type range of Android or IOS type and belongs to a matching condition, and when the type information of the detection item is empty, the detection item is defined as belonging to the vulnerability influence type range of Android or IOS type and also belongs to the matching condition, and the detection item is not limited by the scope of the invention.
S302: and judging whether the version information of each detection item is matched with the vulnerability influence version range information of the test case set to be executed.
In specific implementation, after the version information of each detection item is read, whether the version information of each detection item is matched with the vulnerability influence version range information of the currently executed test case set is respectively judged. If the version information of the detection item does not belong to the range of the vulnerability influence version range information of the currently executed test case set, the version information is considered not to be matched; otherwise, a match is considered. Wherein the matching case comprises: the version information of the detection item belongs to vulnerability influence version range information of the currently executed test case set, and the detection item has no version information, and the like, which is not limited by the invention. The case of mismatch is: and detecting whether the version information of the item is not in the vulnerability influence version range information of the currently executed test case set. For example, the vulnerability influence version range information of the currently executed test case set is 1.0-3.0 version, and when the version information of the detection item is 5.0, the vulnerability influence version range is not in the 1.0-3.0 version, and the vulnerability influence version range is not matched; when the version information of the detection item is 2.0, the vulnerability influence version range belongs to the vulnerability influence version range of 1.0-3.0 version, and belongs to the matching condition, and when the version information of the detection item is empty, the vulnerability influence version range belongs to the vulnerability influence version range of 1.0-3.0 version, and also belongs to the matching condition, and the invention is not limited by the scope.
The above steps S301 and S302 do not have a sequence, and it is determined which step is performed first, and the process of determining each detection item is not in the sequence. In step S105, the current test case set is executed on each of the matched detection items, and after the current test case set is executed on all the matched detection items, the last test result of the current test case set is obtained.
In an embodiment, the vulnerability detection method for an intelligent terminal device provided by the present invention further includes:
performing communication interaction with the Bluetooth module; or
And carrying out communication interaction with the wifi module.
During specific implementation, a test case set is executed on the bluetooth module 204 of the intelligent terminal device to be detected, and when vulnerability detection is performed, testing needs to be performed in a state of communication interaction with the bluetooth module 204 (that is, the bluetooth function state of the intelligent terminal device to be detected is started). When the test case set is executed on the wifi module 205 of the intelligent terminal device to perform vulnerability detection, the testing needs to be performed in a state of communication interaction with the wifi module 205 (i.e. the wifi function state of the intelligent terminal device to be detected is started).
In one embodiment, the step S106 of determining whether the intelligent terminal device to be detected has a bug according to the test result includes:
judging whether the behavior characteristics corresponding to the test case set occur in the intelligent terminal equipment to be detected or not according to the test result; if so, the vulnerability corresponding to the test case set exists in the intelligent terminal equipment to be detected; otherwise, the intelligent terminal device to be detected does not have the bug corresponding to the test case set.
In specific implementation, whether the current detected intelligent terminal device has the bug corresponding to the test case set is judged according to the test result obtained in step S105. By checking whether the behavior characteristics of the vulnerability corresponding to the test case set occur in the test result, if the behavior characteristics corresponding to the vulnerability occur, the vulnerability corresponding to the test case set exists in the currently detected intelligent terminal device, otherwise, the vulnerability corresponding to the test case set does not exist.
In an embodiment, as shown in fig. 3, the vulnerability detection method of the intelligent terminal device provided by the present invention further includes:
s107: and for each vulnerability, after the test result of the test case set corresponding to the vulnerability is judged, restoring the intelligent terminal device to be detected to be in an initial state, and executing the test case set corresponding to the next vulnerability.
In specific implementation, for each bug in S101, after the test result of executing the test case set in each matched detection item is determined in S106, each detection item of the detected intelligent terminal device is restored to the initial state (the initial state is the state of the detected intelligent terminal device before the test case set is executed), and then the next test case set corresponding to the next bug is executed. By restoring the detection items of the detected intelligent terminal equipment to be in the initial state, the testing environment before the test case set corresponding to each bug is executed is ensured to be consistent, and the mutual influence among the bugs is avoided.
According to the analysis, the behavior characteristics and vulnerability influence range information of each vulnerability of the intelligent terminal equipment are obtained, and the test case set triggering the vulnerability is compiled according to the behavior characteristics and vulnerability influence range information. During detection, firstly, information of detection items of the intelligent terminal device to be detected is read, whether the information of each detection item is matched with vulnerability influence range information of a test case set to be executed or not is judged, the corresponding test case set is executed on the matched detection items, a test result is obtained, then whether the corresponding vulnerability exists in the intelligent terminal device to be detected or not is judged according to the test result, the detected intelligent terminal device is recovered to be in an initial state after the judgment is finished, and then the test case set corresponding to the next vulnerability is executed. The vulnerability detection method of the intelligent terminal equipment provided by the invention solves the defects in the prior art, realizes the adaptation to various intelligent terminal equipment, and has the beneficial effects of quickly and effectively automatically detecting various vulnerabilities of different detection items for the intelligent terminal equipment.
