Blockchain has become a hot issue in global technology and economy with its anti-tampering, transparency and decentralization. Blockchain infrastructure carries various blockchain applications on the top and connects network infrastructure on the bottom, and therefore its security is key to the high-quality development of blockchain. This paper surveys the effort of global governments, industries and standardization institutions in blockchain infrastructure security.Then it analyzes the security risks of blockchain infrastructure and ends up with the corresponding security evaluation indicators to evaluate the ability of blockchain infrastructure in tackling security risks.
In order to accelerate the application of the security maturity model in important areas of the Industrial Internet, on February 25, 2019, the American Industrial Internet Industry Alliance released the “IoT Security Maturity Model: Practitioners Guide” to build a comprehensive security maturity model, Formed a dynamic industrial Internet security assessment process, and successfully applied the model to conduct security practice assessment work. In this regard, China should pay full attention to speeding up the implementation of safety assessment management practices in key areas, speeding up the development of safety evaluation standards, accelerating the application of safety practices in key areas, strengthening the building of security situation awareness capabilities, and playing the role of bridges of Chinas industrial alliance to build a complete and reliable Industrial Internet security assessment system.
