Hi everyone, While working on a cloud security project, I faced an issue where I deployed a multi-tenant cloud application on a public cloud provider, but I am concerned about data isolation, access control, and compliance risks between tenants.
I checked IAM policies, encryption settings, and audit logs, and everything looks configured, but still I am not confident that data is properly isolated and protected from unauthorized access between tenants.
I have been exploring CCSK exam topics from CSA (Cloud Security Alliance) for the Certificate of Cloud Security Knowledge Certification and also using resources like Study4Exam for CCSK practice questions. This helps me understand my concerns a little bit, but I want to understand the real issue behind this scenario.
What could be the possible reasons for this problem?

The issue may come from weak tenant isolation even if IAM, encryption and logs look correct.
In multi tenant cloud apps, risks often appear in the application logic, shared databases, APIs, caches, logs, backups or service accounts where one tenant data could be accessed by another due to missing tenant validation or over permissive roles.
You need to enforce the tenant checks in every request and use least privilege access and don't forget to separate partition tenant data and you isolate encryption keys where needed regularly perform security testing and compliance reviews.
