The present invention provides a method and device for preventing attacks on an operating system based on native codes. The target framework source code related to preset functions is selected from the framework source code corresponding to the application program framework layer of the operating system, and the source code of the target framework is obtained. The system directory called. Construct the attack code that runs under the native code of the operating system according to the target instruction calling the system directory in the instruction source code, and repair the operating system according to the target attack code that successfully attacks the operating system. After finding the target instruction that consumes system resources and device resources, build the attack code based on the native code of the operating system, and run the attack code to find the vulnerable points based on the native code in the operating system. It realizes the detection and repair of the vulnerable points in the operating system based on the native code layer, and eliminates the hidden dangers of the operation process of the operating system.
Description
technical field [0001] The invention relates to the technical field of operating system security, in particular to a method and device for preventing attacks on operating systems based on native codes. Background technique [0002] The operating system is a computer program that manages the hardware and software resources of a machine, and is also the core and cornerstone of the machine system. The operating system needs to handle basic tasks such as managing and configuring memory, determining the priority of system resource supply and demand, controlling input devices and output devices, operating the network, and managing file systems. At the same time, the operating system also provides an operation interface for users to interact with the system. However, the operating system is often attacked because of vulnerabilities. How to detect the vulnerabilities in the operating system and how to repair the vulnerabilities have become two important aspects to ensure the safe op...
