Embodiment approach

[0072] A) The hook program is used to capture the interface function of the terminal operating system to send or receive network data, and when the interface function is captured, the data packet to be sent or to be received pointed to by the interface function is intercepted.

[0073] The Hook mechanism allows applications to intercept operating system messages or specific events. It is a message processing mechanism in the operating system. Applications can set subroutines on it to monitor certain messages of specific interface functions provided by the operating system. , such as the interface function for sending and receiving network data, the implementation of the hook mechanism can be achieved by: obtaining a hook plug-in corresponding to a specific event behavior from a background sandbox HOOK framework, and using the hook plug-in to monitor the specific event behavior of the target application. Achieved. The background sandbox HOOK framework can be centrally managed o...

Abstract

The embodiment of the invention relates to a data detection method and a data detection device. The data detection method comprises the following steps: intercepting a data packet flowing through a network data transmission interface by monitoring a network data transmission interface of a terminal operating system; according to preset safety rules, scanning the data packet; if the data packet contains non-safe data content, processing the non-safe data content; and returning the processed data packet to the network data transmission interface for carrying out data transmission, so that the problems that a terminal is invaded by malicious data and a system or user data is threaten are solved, early inspection of the data packet which enters or is output from the terminal is realized, and the malicious data is timely found, so that security and reliability of data interaction in the terminal are guaranteed.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of network security, and in particular, to a data detection method and device. Background technique [0002] With the popularity of smart mobile terminals, the types and quantities of smart mobile terminal applications are becoming more and more abundant. [0003] The ensuing problem is that hackers and virus makers attach web crawlers or malicious plug-ins to various user-interactive network data such as web pages, applications, and text messages, resulting in leakage of user information, reception of spam or fraudulent text messages, virus planting, etc. Instabilities or crashes of the system caused by entering the operating system, additional costs caused by users accidentally clicking on phishing websites or malicious links, etc. All of the above problems make users more worried about their mobile devices while enjoying the convenience and entertainment brought by smart mobile t...
