With the continuous growth of enterprise data,storage security in software-defined data center SDDC environments has become one of the biggest challenges faced by many enterprises.In this paper,an autonomous and controllable security architecture is designed based on software-defined network(SDN)and soft wove-defined storage(SDS).This architecture can reduce the risk of storage data being attacked and leaked,a nd improve storage security.The experimental results based on OpenStack private cloud platform show that the design can provide more secure,flexible,reliable and efficient storage services for enterprises,and provide a new development direction for storage security research.
