Embodiment Construction

[0102] The method, device and system for identifying webpage tampering provided by the present invention will be described in more detail below with reference to the accompanying drawings and embodiments.

[0103] Specifically, the method for identifying webpage tampering provided by the embodiment of the present invention is realized through interaction between the website side and the scanner, and the scanner can be installed in the test client. The scanner will periodically obtain the same monitored page from the website, and identify page tampering according to the monitored page that the website responds to the scanner in different periods. In this way, after the website sends out the page, the client can judge whether the received page has been tampered with after receiving the page sent by the website side, so that the recognition of webpage tampering is more accurate.

[0104] Specifically, an embodiment of the present invention provides a method for identifying webpag...

Abstract

The invention provides a method, scanner, device and system for identifying webpage distortion. The method comprises the steps of receiving an expected page element set, sent by a website side through a first page response, of a monitored page, receiving a real page element set and a refreshed page element set sent by the website side through a second page response, calculating a reference page element set according to the expected page element set, the real page element set and the refreshed page element set, and judging whether the monitored page is distorted or not according to the reference page element set, the real page element set and the expected page element set. According to the method, the aim of judging whether the monitored page is distorted or not on the side of the canner is achieved, that is, in the view of a client side, webpage distortion is identified, and the situation that in the prior art, a method for identifying the webpage distortion cannot accurately judge whether the webpage is distorted or not is avoided.

Description

technical field [0001] The invention relates to the technical field of network security, in particular to a web page tampering identification method, scanner, device and system.
