Abstract
This paper introduces the related concepts,development trajectories,basic components,challenges and opportunities of artificial intelligence and intelligent security.The paper first reviews the three development waves of artificial intelligence,as well as some mechanisms of human brain work,such as prediction and feedback,brain connections,memory,attention and multimodal neurons.Then,the paper analyzes the basic components of intelligent systems,including perception,cognition,understanding,decision-making,action and feedback.Next,the paper discusses the meaning and classification of intelligent security,as well as the four quadrants of giving security to intelligence and giving intelligence to security.The paper also proposes an intelligent security autonomy model,which divides the autonomous decision-making ability of threat detection and protection of security systems into five levels.Finally,the paper points out the challenges faced by the application of artificial intelligence in the field of network security,such as non-closed problem space,asymmetric sample space,unexplainable reasoning results,degradation of generalization ability,etc.,and looks forward to future research directions.
