Understand the client's cloud infrastructure setup, including services used on AWS, Azure, and GCP, as well as their security requirements and compliance standards.

Define the scope of the penetration testing, including specific cloud services, regions, and configurations to be assessed.

Gather information about the client's cloud assets, including virtual machines, storage buckets, databases, networking configurations, and access control mechanisms.

Attempt to exploit identified vulnerabilities to demonstrate their impact and validate their severity, ensuring realistic assessment of cloud infrastructure security.

Generate a detailed technical report outlining the methodology, findings, exploitation techniques, and proof-of-concept demonstrations for each identified. Provide an executive summary highlighting key findings, risk assessment, and actionable recommendations for improving cloud security posture.

Once the remediation has been completed, the tester may conduct a retest to verify that the vulnerabilities have been successfully addressed and that the cloud environment is now secure.
