Introduction

• Cloud Computing is the practice of using a network of remote servers hosted on the Internet to store, manage and process the data

• Software-as-a-Service(SaaS) gives the capability to use applications supplied by the service provider in a cloud infrastructure

• Since clouds are shared by different ASPs they are vulnerable to malicious attacks

AGENDA:

• Objectives of project.• Problem definition.• Methodology.• References.

OBJECTIVE:

The main aim of this system is to provide scalable and effective service integrity attestation framework for SaaS clouds, using IntTest framework.

PROBLEM DEFINITION:

• SaaS cloud systems involve massive cloud computing infrastructures.

• Due to their sharing nature they are vulnerable to malicious attacks.

EXISTING SYSTEM:

• SaaS cloud system enable application service providers to deliver their applications via massive cloud computing infrastructure.

• This sharing nature makes SaaS clouds vulnerable.

• Requires special trusted hardware.

EXISTING SYSTEMDATA

PROPOSED SYSTEM:

• We propose IntTest,a scalable and effective service integrity attestation framework for SaaS clouds.

• It automatically enhance result quality.

• Higher pinpointing accuracy.• Does not require special hardware.

IntTest Framework

PROPOSED SYSTEMDATA

ALGORITHMS:

1. Baseline Attestation Scheme.(RBCC)

2. Integrated Attestation Scheme.

3. Result Auto-Correction.

Integrated Attestation Scheme:

Step 1: Consistency graph analysis.

Step 2:Inconsistency graph analysis.

Step 3:Combining consistency and inconsistency graph analysis result.

Consistency graph analysis and Inconsistency graph analysis

Integrated Attestation Scheme

Result Auto-Correction

Conclusion:

• IntTest framework checks for consistency and inconsistency relationship between service providers.

• IntTest achieves higher pinpoint accuracy.

• IntTest replaces corrupted data with good results provided by benign service providers.
