Abstract

The invention discloses a detection method of web shell and a web server, relates to the field of information security, and mainly aims to detect the web shell in the web server rapidly and accurately in order to protect the security of the web server. According to the major technical scheme of the invention, the method comprises the following steps: constructing a web script virtual machine running a web server script; acquiring web script parameters of web scrip running according to different testing aims; running the web script parameters and the detected web server script on the web script virtual machine, and recording a process behavior in the running process of the web server script; matching the process behavior with a predetermined malicious script rule base; if the matching is successful, determining that the web server script is the web shell. The detection method is mainly applied to the detection process of the web shell.

Description

technical field [0001] The invention relates to the field of information security, in particular to a method for detecting a web shell and a web server. Background technique [0002] With the rapid development of Internet technology, Internet information security has become the focus of people's increasing attention. The web shell is a script attack tool for web intrusion. Simply put, a web shell is an Active Server Page (asp) or Hypertext Preprocessing Language (Hypertext Preprocessor, php) Trojan backdoor. After hackers invade a website, they often use these asp or php Trojans The backdoor file is placed in the web directory of the website server and mixed with normal webpage files. Then hackers can use the web to control the website server through the asp or php Trojan horse backdoor, including uploading and downloading files, viewing databases, and executing arbitrary program commands. [0003] At present, we often detect whether there is a web shell through static de...
