Application service providers can now offer their programs on enormous computer networks in the cloud thanks to software-as-a-service (SaaS) cloud platforms. Because SaaS clouds are shared, they can be attacked by malicious actors. In this paper, we will look at the Int Test. It is a scalable and successful technique for demonstrating the trustworthiness of SaaS cloud services. Int Test's new integrated attestation graph analysis method, when compared to prior techniques, provides for more exact identification of attackers. Furthermore, Int Test can rapidly improve the quality of results by replacing bad results from hostile attackers with good results from reliable service providers. The IBM System S stream processing applications were used to develop and evaluate a variant of the Int evaluate system in a real-world cloud computing environment. Our findings show that Int Test can pinpoint an attacker with more accuracy than existing methods. Int Test can be used in large-scale cloud systems because it does not require specialist hardware or secure kernel support and does not dramatically slow down the software.
