Dependability and security become increasingly important for distributed systems. In this paper, we present a novel fault-tolerant scheme for providing dependability and security in distributed systems through fault scheme and security scheme. Our mechanism is different from other works because our research focuses on building a scalable, adaptive and dependable management mechanism which is a combination of QoS management, failure management, and security management. Quality of Service (QoS) management manage the delay, delay variation (jitter), bandwidth, and packet loss parameters on distributed systems. Failure management to ensure the distributed systems has strong dependability, while security management to ensure the information within the system has secure guarantee. Our performance analysis shows that the executing time of algorithm is negligible compares to the running time of the distributed application program. So our algorithm can be applied to the larger-scale distributing application.
