Problems solved by technology
[0003] While mobile applications bring convenience to users' life and work, they also bring security risks. Some applications directly implant malicious or bad programs through technical means to bypass detection, and some applications do not carry any security information when they are installed. Bad modules are loaded by users after installation, which damages the interests of users; and as various applications spring up online, the cost for users to choose safe and good experience applications is also getting higher and higher

Embodiment Construction
[0031] The present invention will be further described below in conjunction with specific examples and accompanying drawings.
[0032] The present invention provides a dynamic update mechanism determination method, such as figure 2 As shown, the behavior analysis of the application is carried out in the cloud.
[0033] The network connection judgment is used to judge whether the application has a network connection through static detection and / or dynamic detection. The network connection judgment is specifically: parse the AndroidManifest.xml file of the application to see if it is configured: If it is configured, it means that the application has a network connection, and if it is not configured, it means that the application does not have a network connection.
[0034] When the application has a network connection, hot update judgment and local code loading judgment are performed; among them, hot update judgment is used to identify whether the application has a dynamic u...

The invention provides a method for judging a dynamic updating mechanism. The method comprises the following steps: performing behavior analysis on an application at a cloud; judging whether the application has network connection or not through static detection and / or dynamic detection; when the network connection exists in the application, performing hot update judgment and local code loading judgment; wherein the hot updating judgment is used for identifying whether the application has a dynamic updating module or not through static detection and / or dynamic detection; wherein the local codeloading judgment is used for identifying whether the application has a local loading module or not and has no local code library; and if the application has a dynamic updating module or has a local loading module and no local code library, judging that the application has a dynamic updating mechanism. Dynamic updating of the application is identified through network connection and hot updating judgment, whether the application updates a bad module or not is found in time, meanwhile, application behavior analysis and detection are carried out at a cloud end, few system resources are occupied, and the operation speed of an operation system and an application program is not affected.
Description
technical field [0001] The invention belongs to the technical field of terminal equipment security, and in particular relates to a dynamic update mechanism determination method and an application life cycle behavior monitoring method. Background technique [0002] Mobile terminals refer to computer devices that can be used on the move, including mobile phones, tablet computers, Pos machines, and even vehicle-mounted computers. With the popularization of mobile terminals, the application of various application programs is also widely used. [0003] While mobile applications bring convenience to users' life and work, they also bring security risks. Some applications directly implant malicious or bad programs through technical means to bypass detection, and some applications do not carry any security information when they are installed. Bad modules are loaded by users after installation, which damages the interests of users; and as various applications spring up online, the co...
