It promotes the optimal scheduling of computing and communication resources, efficient processing of massive government information, and the sharing and application of government big data. However, these technologies have also brought security threats that cannot be ignored. Based on the analysis of the development trend in e-government systems and technologies at home and abroad, this paper studies the characteristics and technical means of new e-government. Furthermore, the security defense technology of new e-government system is analyzed and discussed.

Key words: e-government, cloud computing, 5th Generation Mobile Networks (5G), security, dynamic defense
