Abstract

The invention discloses a method for realizing a lightweight class JavaScript sandbox. The method comprises the following steps of: S10, defining access control inside the sandbox; S11, automatically generating a sandbox monitoring code according to the defined access control; S12, automatically generating a monitoring code for stopping an access function according to the defined access control; and S13, detecting a malicious code inside the sandbox in real time, and stopping calling a dangerous function. The method for realizing the lightweight class JavaScript sandbox provided by the invention is simple and effective; a programmer can conveniently grasp and operate the method for realizing the lightweight class JavaScript sandbox; the JavaScript program code is safely executed inside the sandbox; and no dangerous program behavior is generated.

Description

technical field [0001] The invention belongs to the technical field of software security, and relates to a method for realizing a lightweight JavaScript sandbox. Background technique [0002] The JavaScript language is a scripting language widely used in Internet applications. The JavaScript language has good expressiveness and flexibility. Using the JavaScript language can improve the flexibility and expressiveness of the software system, and improve the readability and readability of the software system. reusability. [0003] The function (function) is the basic structure of the JavaScript language. The JavaScript program is composed of a group of functions. Only by ensuring the safe and reliable execution of the target JavaScript function can the JavaScript program be executed safely and reliably without generating dangerous and malicious programs. Behavior. The JavaScript language supports runtime evaluation (runtime evaluation) grammatical features. Many software syst...
