Dependability analysis of the Web Services (WSs), dsclosure of possible failure modes and their effects are open problems. This paper gives results of the Web Services dependability analysis using standardized FMEA- (Failure Modes and Effects Analysis) technique and its proposed modification IMEA- (Intrusion Modes and Effects Analysis) technique. Obtained results of FMEA-technique application were used for determining the necessary means of error recovery, fault prevention, fault-tolerance ensuring and fault removal. Systematization and analysis of WS intrusions and means of intrusion-tolerance were fulfilled by use of IMEA-technique. We also propose the architectures of the fault and intrusion-tolerant Web Services based on the components diversity and dynamical reconfiguration as well as discuss principles and results of dependable and secure Web Services development and deployment by use of F(I)MEA-technique and multiversion approach.
