The invention discloses a Web asset identification method and device based on
multiple modes, and relates to the technical field of network asset security. The method comprises the following steps: acquiring multi-
modal Web asset information, namely scanning web assets to extract
server information, acquiring Web behavior characteristics and extracting Web
home page information; based on the multi-
modal Web asset information, establishing a multi-
modal model of assets, including a
machine classification discrimination model for identifying interface
layout, a
machine classification discrimination model for identifying interface pictures, and an interaction behavior model for identifying interaction behaviors; and identifying different types of asset information by using a multi-modal model. By using the technical scheme of the invention, richer and more complete asset information can be obtained, technical sources behind assets can be identified, and a
solid foundation is laid for subsequent work of
vulnerability analysis, risk early warning and the like.
