IAM Policies:
Oracle NoSQL Database Cloud Service usesOCI IAM policiesto control access to tables. These policies specify who (user or group) can perform what actions (read, write, delete) on specific database resources. This centralized approach allows for granular permission control, supporting the principle ofleast privilege.
IAM policies are configured at theOCI tenancy leveland can be customized to define access based onusers, groups, and dynamic groups. They are essential for maintaining secure data access, especially in multi- tenant environments.
Why the other options are incorrect:
* A:VCN security lists control network traffic, not table-level access.
* C:Database Vault is for fine-grained access control within traditional Oracle Databases, not NoSQL.
* D:TDE handles data encryption, not access management.
