摘要：A public cloud provides a scalable access to the computing resourcesandIT resources. In addition to these services it should also posses the level of security when it comes to dynamic groups We propose a dynamic group system to implement Multi-Level Security using Bell-Lapadula Model to distinguish the users in the dynamic group by their roles in the organization. This technique allows the user to permit the required privileges for a selected group based on the level of the model and also initializing fault-tolerance by providing back-up facilities to the servers by improving the availability in the cloud.
