With the continuous development of the network and the rapid growth of users' demand for network use , The scale of the network continues to expand 、 Cyberspace tends to be complex . Asset detection through cyberspace , Potential safety risks can be found in time , Avoid being attacked by outlaws . When the country raises the concept of Cyberspace Security to an important level , It is more important . In the network attack and defense confrontation , First of all, we have to understand the network , To understand cyberspace , We need to detect assets in cyberspace .

As an important basic technology of network security, cyberspace asset detection technology , It is through active or passive detection , To draw the network node and network connection diagram of devices in cyberspace , Portrait network devices .

In recent years , Network asset detection technology has become a research hotspot in the field of network security , All countries have conducted in-depth research on this . Such as the advanced research projects agency of the United States Department of defense （Defense Advanced Resear
