Step-by-step explanation:
To provide restricted and time-limited access to databases that don't have public endpoints in Oracle Cloud Infrastructure (OCI), you should use the OCI Data Safe service. OCI Data Safe provides advanced security features such as data discovery, vulnerability assessment, and user activity auditing. It allows you to define and enforce security policies, monitor user activity, and apply data protection controls.
