A cloud security assessment evaluates the security of cloud computing infrastructure, services, applications, and data to identify potential risks and vulnerabilities. It involves using various security testing methods and tools to assess the security posture of cloud systems and determine if the security controls effectively protect against unauthorized access, data breaches, and other security threats. Internal security teams or third-party security providers can conduct cloud security assessments. The assessment can be done on a one-time basis or as part of an ongoing monitoring and testing program to ensure the continuous security of cloud systems.
