Abstract

The embodiment of the invention provides a Java malicious command execution protection method and device. A Java virtual machine executes a command sent by a target program and triggers a monitoring point to monitor the target program; the monitoring point obtains an execution thread of the command sent by the target program, and detects a stack of the execution thread to obtain a category of an execution code of the command; and if the category of the execution code is not stored on the preset white list, the monitoring point gives an alarm through a dynamic alarm module. A small number of monitoring points are set on the Java virtual machine to monitor the target program, so that the performance loss of the Java virtual machine is reduced; by judging that the category of the execution code is not in the preset white list, unknown vulnerabilities can be protected.

Description

technical field [0001] The invention relates to the technical field of network security, in particular to a method and device for protecting Java malicious command execution. Background technique [0002] Java script attacks can execute arbitrary commands on the operating system, causing great harm. [0003] At present, the protection method of Java malicious command execution mainly sets monitoring points for common vulnerabilities, obtains the code that executes the command, performs black rule matching on the code that executes the command, and sends an alarm to the code that hits the black rule. [0004] Matching based on black rules can only protect against known vulnerabilities, and a large number of monitoring points will affect performance. Contents of the invention [0005] Aiming at the problems in the prior art, the embodiment of the present invention provides a method and device for protecting Java malicious command execution. [0006] Specifically, the embod...
