Control from anywhere and at anytime is nowadays a matter of paramount importance in\ critical systems. This is the case of the Smart Grid and its domains which should be monitored through\ intelligent and dynamic mechanisms able to anticipate, detect and respond before disruptions arise\ within the system. Given this fact and its importance for social welfare and the economy, a model for\ wide-area situational awareness is proposed in this paper. The model is based on a set of current\ technologies such as the wireless sensor networks, the ISA100.11a standard and cloud-computing\ together with a set of high-level functional services. These services include global and local support for\ prevention through a simple forecast scheme, detection of anomalies in the observation tasks,\ response to incidents, tests of accuracy and maintenance, as well as recovery of states and control in\ crisis situations.

During the last decade, the Cloud Computing paradigm has emerged as a panacea for many problems in traditional IT infrastructures. Much has been said about the potential of Cloud Computing in the Smart Grid context, but unfortunately it is still relegated to a second layer when it comes to critical systems. Although the advantages of outsourcing those kind of applications to the cloud is clear, data confidentiality and operational privacy stand as mayor drawbacks. In this paper, we try to give some hints on which security mechanisms and more specific, which cryptographic schemes, will help a better integration of Smart Grids and Clouds. We propose the use of Virtual SCADA in the Cloud (VS-Cloud) as a mean to improve reliability and efficiency whilst maintaining the same protection level as in traditional SCADA architectures.
