Abstract

The invention discloses a memory page active merging technology based sandbox concurrence method. The method comprises the steps of building a sandbox template in an initialized sandbox system and calibrating a basic memory page set; receiving a new task by the sandbox system, copying a virtual magnetic disk of the sandbox template to a new position, recording the position, and writing files and configuration of the new task into a new virtual magnetic disk; and generating a new sandbox based on the sandbox template, carrying out specific setting on the new sandbox, enabling the memory page set in the new sandbox to be in consistence with the basic memory page set of the sandbox template before the setting, and changing the memory page which requires change after the setting. The technical scheme can solve the technical problems that a portion with possibly little memory change of the operating system cannot be notified actively, resident sets of each sandbox system are reduced, and the memory utilization of the sandbox system cannot be optimized efficiently.

Description

technical field [0001] The present invention relates to the technical field of computer security, and in particular to a sandbox concurrency method and system based on memory page active merging technology. Background technique [0002] At present, many optimizations for the memory utilization of the sandbox system are transferred from the field of virtualization. For example: linux discovers the same pages through active memory scanning, and performs page consolidation. However, since the sandbox system runs in batches, the single running time is very short, and active memory scanning requires a relatively stable environment and sufficient time; and during the system startup process, the memory will also change drastically, so this technology cannot work effectively. [0003] However, since the sandbox system runs in batches and the operating environment is highly consistent, after the operating system is loaded, the amount of change is small. Failure to proactively infor...
