Providing security at all levels within the multi-platform cloud-computing environment is still not considered to be properly solved due to a variety of problems arising from technical and human-based sources. We have developed authentication-and-authorization solution based on the Single Sign-On (SSO) approach for cloud-service users and administrators in a multi-platform environment. The system developed enables user authentication for clouds provided as Infrastructure as a Service system built up from different OS systems. The solution enables the use of different services based on credentials that are authenticated only once and enable simple and efficient administration of the relevant data.
