A network function virtualization security and trust system includes a network device that operates as a virtualized network device with virtualized services provided on the network device by network nodes included in the system. Security and trust within the system can include hardware authentication of the network nodes and the network device to obtain a level of security of the hardware provisioning the operation of the virtualized services. Security and trust can also include authentication of the services being used on the virtualized network device. Services authentication can be based on monitoring and analysis of the cooperative operation of the services in the virtualized network device. The virtualized services can be dynamically changed, added or stopped. Hardware authentication and dynamic services authentication in accordance with changes in the virtualized services can dynamically maintain a level of security across the devices and the virtualized services.
