Ensure there is only one active API Key for any single OCI IAM user

AltaNivel 1Automatizadaoci

Descripción

API Keys are long-term credentials for an OCI IAM user. They can be used to make programmatic requests to the OCI APIs directly or via, OCI SDKs or the OCI CLI. Having a single API Key for an OCI IAM reduces attack surface area and makes it easier to manage. No ACTIVE user may have more than one ACTIVE API key. Read-only OCI CLI calls; credentials and home region come from the CLI's normal configuration (~/.oci/config, OCI_CLI_PROFILE, OCI_CLI_AUTH). The tenancy OCID is taken from OCI_TENANCY or the first tenancy= line of the config file. A missing CLI or credential fails the check.

Salida esperada: compliant

Cómo se corrige

Método de corrección: Guía o parche de infraestructura

Delete all but one API key for each listed user (oci iam user api-key delete --user-id <ocid> --fingerprint <fp>).
