Cloud computing has become integral to modern organizational operations, offering efficiency and agility. However, security challenges such as data loss and downtime necessitate tailored compliance solutions. Risk assessment is crucial for identifying and mitigating cloud-related threats, yet a standardized approach remains elusive. Our study aims to fill this gap by conducting a systematic mapping study on the prevailing methodologies. Through a meticulous analysis of 21 scholarly papers, we explore various aspects of security risk assessment for the cloud. The results provide valuable insights into delivery models, standards, and validation practices, contributing to a comprehensive understanding of cloud risk assessment.
