Abstract: With the rapid development of network technology, the security problem has become more and more serious as the number and types of assets in cyberspace have become more and more complex, which poses a new challenge to the management department of cyber security. DCLingCloud NetSensor Network Traffic Analysis Solution is an endtoend network monitoring solution that adopts the selfdeveloped and patentedbased protocol analysis on multicore processors technology. The solution is proved to have the best packet capture performance in the industry. It has a unique architecture that integrates network volume and network security analysis into one platform among all competitors. Native cloud is also fully supported. Fullsize data packets analysis is creatively integrated into the detection of network security issues and backtracking audit. Thus, this solution has the ability of network application traffic analysis and cyber security analysis and can provide the entire raw data for users for network security guarantee.Key words cyber security; network traffic analysis; network forensic; network packets; attack detection
