Abstract: The Google Cloud Platform requires customers who want cloud security to fully understand the shared responsibility model, as their security obligations differ from the provider's duties. Through an in-depth analysis, the paper presents organizations with a practical approach to achieve data security along with compliance standards in Google Cloud. Google Cloud secures its underlying infrastructure, yet customers accept full accountability to protect their data applications along with configurations within the cloud system. This paper explains the security obligations between Google Cloud and its users by providing practical security implementation guidelines for robust safeguards. This document examines complete cloud security management through its key components of data protection, alongside access management and compliance guidelines, together with incident response systems. Organizations achieve risk reduction and improve security standing while meeting regulatory standards in Google Cloud through the proper use of the shared responsibility model.

Keywords: Shared Responsibility Model, Google Cloud Security, Cloud Compliance and Governance, Identity and Access Management (IAM), Data Protection in Cloud Computing, Incident Response in GCP.
