Software-as-a-Service (SaaS) cloud systems change application service suppliers to deliver their applications via huge cloud computing infrastructures. However, as a result of their sharing nature, SaaS clouds square measure at risk of malicious attacks. During this paper, the authors have a tendency to gift IntTest, a scalable and effective service integrity attestation framework for SaaS clouds. IntTest gives a completely unique integrated attestation graph analysis theme which will provide stronger aggressor pinpointing power than previous schemes. Moreover, IntTest will mechanically enhance result quality by replacement dangerous results created by malicious attackers with sensible results created by benign service suppliers.
