Network auditing method, device and system based on Linux process function

Abstract

The invention discloses a network auditing method and device based on a Linux process function, a terminal and a storage medium thereof. The network auditing method comprises the following steps: running an agent process; rewriting a corresponding process function in the dynamic library, so the process function can read and write network communication information of the running process; setting an environment variable LD_PRELOAD, and generating a sub-process through the agent process; mapping the sub-process as an auditing process by calling a function; calling the process function to obtain network communication data of the sub-process; and sending the network communication data to the proxy process. According to the network auditing method based on the Linux process function, network behaviors can be counted in real time, and therefore accurate monitoring and auditing of computing resources of terminal equipment such as a convergence optical modem are achieved.

Description

technical field [0001] The invention relates to the technical field of network data processing, in particular to a network audit method, device, system and storage medium based on Linux process functions. Background technique [0002] With the continuous development of the Internet, the computing scale and computing cost of various applications are constantly increasing. For example, machine learning, 3D rendering, and scientific computing are sensitive to data and computing performance. Resources such as VR, AR, 4K, and 8K are critical to bandwidth and Storage requirements are increasing day by day. This poses a challenge to the actual software and hardware solutions for security audits. Therefore, how to implement accurate and real-time network audits for enterprise applications without sacrificing performance or paying less performance costs has become a technical focus. [0003] The network audit technology in the related art usually uses network card counters, network ...
