In recent years, the sharing of cybersecurity threat intelligence (hereinafter referred to as threat intelligence) has received increasing attention from national network security management organizations and network security enterprises. Academia and industry have conducted research on threat intelligence analysis and sharing. This paper first introduces the value and significance of threat intelligence. Then it introduces the commonly used threat intelligence analysis model. Then it organizes and classifies the threat intelligence sharing norms and threat intelligence vendors. Then it starts from the main problems faced by threat intelligence sharing. A solution to build regional network security capabilities is presented; finally, the future research direction of threat intelligence sharing is explored.

Internet, big data, global society, economy, life, politics, military, and culture are deeply integrated and have developed into an era of overlapping cyberspace and real society. Cyberspace security has become the most complex, comprehensive, and severe non-traditional security challenge facing all countries in the world. However, the talents in the field of cyberspace security cannot meet the practical needs of the development of cyberspace security. This paper puts forward the training scheme of network security talents, discusses the relationship between knowledge atlas and network space security, gives the construction and distribution of network space full knowledge atlas, and then constructs an education big data architecture for cyberspace security based on knowledge graph around the use of knowledge.
