Problems solved by technology

But the regular check scheme must be a trade-off between performance and security
If the check interval is set too long, it may cause some attacks that could have been successfully detected to be missed, or detected after the attack is successful, which may lead to irreparable losses, such as leakage of confidential data; if the check interval If the setting is too short, it may greatly increase the additional load of the system, thus affecting the normal execution and resulting in a decrease in the availability of the system

Abstract

The present invention discloses a method, an apparatus, and a system for triggering virtual machine introspection, so as to provide a timely and effective security check triggering mechanism. In the present invention, data that needs to be protected is determined; the data that needs to be protected is monitored; and when it is determineed that the data that needs to be protected is modified, virtual machine introspection is triggered. The present invention avoids a performance loss and a security problem that are brought about by regularly starting a virtual machine introspection system to perform a security check, and therefore, the present invention is more applicable.

Description

technical field [0001] The present invention relates to the technical field of virtual machines, in particular to a method, device and system for triggering virtual machine introspection. Background technique [0002] In recent years, with the popularization of personal computers, mobile computing devices, and cloud computing, computer security has become a hot spot that people pay more and more attention to. People save a lot of critical data on various devices, including emails, private photos, bank account numbers and passwords, social network accounts, etc., which makes the device itself a target for hackers. How to improve computer security has become a key problem to be solved urgently. [0003] VMI (Virtual Machine Introspection, virtual machine introspection) is a method applied in a virtualization environment, using a VMM (Virtual Machine Monitor, virtual machine monitor) to enhance the security of a virtual machine from outside the virtual machine. This technolog...
