 - **Principle of Least Privilege:** Grant only the necessary permissions and regularly audit your [IAM policies](https://www.ateam-oracle.com/post/oci-iam-policies-best-practices).
 - **Breakglass Administrator:** Do not use the out-of-the-box OCI Adminstrator account for day-to-day operations. Configure additional administrators based on least privileges and secure the OCI Administrator account as a breakglass account, reserved for emergency use only, as defined in the [OCI IAM Security Best Practices](https://docs.oracle.com/en-us/iaas/Content/Security/Reference/iam_security.htm#Securing_IAM).
 - **Multi‑Factor Authentication (MFA):** Enable MFA for all users to protect against unauthorized access. Additional best practices are detailed in the [OCI IAM Security Best Practices](https://docs.oracle.com/en-us/iaas/Content/Security/Reference/iam_security.htm#Securing_IAM).

A number of [security dashboards](https://blogs.oracle.com/observability/post/oracle-cloud-infrastructure-security-fundamentals-dashboards-using-oci-logging-analytics) have been published to help you gain rapid visibility into your operational security metrics.
