A distributed asset identification and change awareness system for implementing vulnerability management includes a plurality of network asset information collection subsystems distributed in different regions and a distributed task scheduling and data processing subsystem, wherein tasks are decomposed based on a distributed architecture and allocated to appropriate resources through the task scheduling, task distribution and processing are realized for a plurality of nodes, and asset information detection and sensing are distributedly performed; the network asset information collection subsystems collect asset information of the networked active host; the data processing part of the distributed task scheduling and data processing subsystem obtains the asset information of the networked active host from the network asset information collection subsystems, and compares the asset information with the confirmed asset attribute information stored in the asset library to realize the automatic update of the asset information for the networked surviving host in the asset library. Vulnerability information is collected though vulnerability scanning, which may quickly treat and fix securityvulnerabilities in networked information systems.
