Network Virtualization Security: Threats, Measures, and Use Cases

With the rapid development of technologies such as $5 G$, cloud computing, and big data, network virtualization technology has been widely applied, effectively improving the utilization of resources such as computing, storage, and network, as well as the flexibility of IT systems or networks, reducing system maintenance costs. However, at the same time, the complexity of network virtualization environment makes security threats more covert and diverse, and traditional security protection methods are difficult to cope with, which also brings many security risks. This article analyzes the current development status and related work of network virtualization, sorts out the security threats of network virtualization, summarizes the characteristics and architecture of network virtualization technology, and further introduces the security measures and typical use cases of network virtualization, which can be used to guide and promote network virtualization security.
