How does PrEstoCloud address security concerns?

The loss of physical control over data which is stored on the cloud-based infrastructure or transmitted over the Internet is one of major concerns for different companies. To come up with such a concern, utilisation of a private cloud may be helpful. Moreover, the “Security Enforcement Mechanism” component defined in the PrEstoCloud architecture is able to enforce protection in the operational layer where the application is running on the cloud. This component is also responsible for improving the network security by instructing the deployment of VNFs (Virtual Network Functions) such as firewalls and IDS (Intrusion Detection Systems) virtual devices.
