OPBUS: Fault Tolerance Against Integrity Attacks in Business Processes

Abstract

Management and automation of business processes have become essential tasks within IT organizations. Nowadays, executable business processes are the most extended kind of operational business processes. They usually use external services which are not under our jurisdiction and an intrusion attack over them could be not controlled, introducing unexpected fault in their execution. Organizations must ensure that their business processes are as dependable as possible before automating them. Fault tolerance techniques provide certain mechanisms to decrease the risk of possible faults in systems. In this work, OPBUS framework is proposed as solution for developing business processes with fault tolerance capabilities. Fault tolerance techniques are applied to resist faults related with integrity attacks over services involved in business processes. To the best of our knowledge, this work is the first approach that achieves a fault tolerance solution over business processes based on checkpoints and rollback using constraint programming.
