1. Virtualization technology accelerates the process of network opening and service, and the traditional method of dividing security boundaries based on entity isolation is no longer applicable. In the virtual environment, management and control functions are highly centralized, resources are shared, and open source software is widely used, so the risk of being attacked and introducing security vulnerabilities increases.

2. Introduction of Edge Computing Technology The edge network infrastructure is exposed in an unsafe physical environment, and its application in the edge computing platform can easily lead to the disclosure of sensitive information of users and enterprises.

3. Network slices are logically isolated from resources shared by * * *, and failure to adopt appropriate security isolation mechanisms and measures will bring security risks.

4. The opening of network capability will open user information, network data and business data from the closed platform inside network operators, increasing the risk of data leakage.
