With the rapid development of the Internet of things, the Internet of things is becoming more and more networked, integrated, and intelligent. At present, most of the smart networking devices on the market have security vulnerabilities. They are in an unprotected state and extremely vulnerable to be attacked. When the terminal is attacked or invaded by the network, the user cannot perceive and control it, which brings serious harm to the information life, even endangers the key infrastructure of the network and national security. In view of the current security situation of the Internet of things, based on AI big data analysis and facing the ubiquitous connection scenario, DAS provides a security management platform integrating asset identification, security detection, security auditing, and security operation, which can realize realtime perception of asset information threats from the five dimensions of asset risk sorting, border security monitoring, cyberspace surveying and mapping, threat intrusion monitoring and security situation awareness, and display the current asset security status in a multidimensional visual form.Key words irregularities; weak password; system vulnerability; cyberspace surveying and mapping; signaling security; border security
