Abstract

The embodiment of the present application discloses a method and a device for improving the security of a Java sandbox. The method for improving the security of the Java sandbox includes: performing a permission check on the code to be checked; judging whether there is a method for bypassing the permission check in the call stack of the code; if there is a method for bypassing the permission check method, it is judged whether there is a signature in the method in the call stack; if there is no signature, it is judged that the code to be checked has a security problem. The security of the Java sandbox can be improved by using the embodiment of the present application.

Description

technical field [0001] The present application relates to the technical field of computer security, in particular to a method and device for improving the security of a Java sandbox. Background technique [0002] In a cloud computing scenario, a user provides code written in Java language, and the cloud computing platform executes the code. Since the code often has many security problems (such as hacker's attack code), it is generally executed in a Java sandbox (JavaSandbox). [0003] The Java sandbox provides an execution environment that restricts code permissions according to policy files. During the code running process of the Java sandbox, when the method checkPermission is called, the security manager (Security Manager) of the Java sandbox will perform permission check on the code. The authority check is used to judge whether the method of each layer in the call stack has the authority in the policy file during the code running process, and the authority may include ...
