Now days cloud computing is an important and hot topic in arena of information technology and computer system. Several companies and educational institutes have been deployed cloud infrastructures to overcome their problems such as easy data access, software updates with minimal cost, large or unlimited storage, efficient cost factor, backup storage and disaster recovery and several other benefits compare with the traditional network infrastructures. In this research paper; Supervisory Control and Data Acquisition (SCADA) system has been deployed within cloud computing environment, to minimized the cost (that are related with real time infrastructure or SCADA implementation) and take the advantages of cloud computing. The command bytes (data) have been transmitted between SCADA nodes and traffic is monitored and controlled simultaneously at master (main controller) site. During communication, security is a major issue because usually, SCADA system and cloud infrastructure had been deployed without any security consideration. In current testbed implementation, strong security mechanism (using cryptography solution) has been deployed, while exchanging commands within cloud environment (SCADA within cloud environment). Several times attacks included "authentication, integrity, confidentiality and non-repudiation" have been lunched, to evaluate the security solution (proposed security solution) and security during abnormal communication.
