Dataverse is Microsoft’s managed data layer for business applications in Dynamics 365 and Power Platform. It stores records in tables, exposes them through APIs, and applies role-based permissions, business rules, and auditing. In practice, it acts like the backend system that app builders and automation flows read from and write to.
Dataverse matters in cyber security because it sits at the center of shared-cloud data handling. If permissions, connectors, plugins, or custom code are misconfigured, an attacker may gain access to records they should not see or alter data across app boundaries. Defenders focus on least privilege, tenant isolation, environment separation, access reviews, and logging. Security testing often looks for over-privileged integrations, unsafe custom logic, and authorization flaws that could expose sensitive business records.
