Abstract

The invention discloses a device for preventing a web page from being distorted, wherein in the device for preventing the web page from being distorted, a network data pack processing device intercepts a network data pack returned from a network server, a page restoring device receives the network data pack intercepted by the network data pack processing device and restores the network data pack into the web page content, a page content comparing unit compares the web page content restored by the page restoring device with a pre-backup web page content corresponding to the restored web page content to determine whether the restored web page content is distorted and notifies a network server takeover device about the information on the distortion of the web page when the restored web page content is determined to be distorted, and when receiving the information on the distortion of the web page, the network server takeover device returns the pre-backup web page content corresponding to the restored web page content to external network users. The invention also provides a method used in the device for preventing the web page from being distorted, and a system using the device for preventing the web page from being distorted.

Description

technical field [0001] The invention relates to the field of network server security, in particular to a device, method and system for preventing webpages on the network server from being tampered with.
