Service Reliability and Availability Analysis of Distributed Software Systems Considering Malware Attack

Distributed systems are widely deployed in industries where high computational capability and low cost are required. Distributed software architecture is very important in the distributed system. However, since most distributed systems are designed based on a network structure, distributed software is very vulnerable to malware attacks. Due to the popularity of distributed system, it is vital to study the effects of malware attack on distributed systems. In this paper, we studied the malware attack behaviors by a Markov process model. The states of the object homogeneous distributed system can be derived by analyzing the Markov model, with which the service reliability and service availability can be further obtained. An illustrative demonstration is also presented.
