Abstract

The invention relates to the technical field of computers, and discloses a tracking method for a Linux application layer to monitor process generation and process behaviors in real time. The method comprises the following steps: S1, establishing a relation between the application layer and a kernel layer based on a netlink socker technology of a Linux system; S2, on the basis of netlink socker communication, obtaining events related to the process in the whole Linux system a through cn_proc, wherein process generation time exists, and then a newly-generated process PID can be obtained; and S3, then by using a ptrace technology provided by the Linux system, tracking, monitoring and specifying the newly generated process PID. According to the application layer process monitoring method, the error-tolerant rate is very high, even if the program crashes due to the internal running error of the program, the whole system crashes, the application layer monitoring process uses a connector mechanism provided by a Linux kernel, and the generation of the Linux process can be obtained by driving ten pieces through cn_proc in real time, and then the conditions of delay and inaccuracy caused by acquiring the generation condition of the Linux process by reading a / proc / PID catalog are avoided.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method and a device for tracking process generation and process behavior of a Linux application layer in real time. Background technique [0002] Linux has become the mainstream system under the current hardware server. With the widespread application of the Linux system, hackers exploit the vulnerabilities of the Linux system itself and various software under the system to obtain the highest authority of the server host, thereby occupying the host. [0003] In the Linux environment, regardless of hacking, or the operation of malicious viruses / trojan horses and other software, all behaviors rely on the program as a medium to run the behavioral logic. Then, as long as all programs under Linux are recorded from the perspective of an "observer", the recording sequence and corresponding call parameters of all system calls of the program, and the analysis is added to know the beh...
