Ensure IAM administrators cannot update tenancy Administrators group

VisokaNivo 1Automatskaoci

Opis

Tenancy administrators can create more users, groups, and policies to provide other service administrators access to OCI resources. For example, an IAM administrator will need to have access to manage resources like compartments, users, groups, dynamic-groups, policies, identity-providers, tenancy tag-namespaces ... These policy statements ensure that no other group can manage tenancy administrator users or the membership to the 'Administrators' group thereby gain or remove tenancy administrator access. Flags root-compartment statements that grant use/manage users or groups in tenancy without a target.group.name != 'Administrators' condition (statements for the Administrators group itself are ignored). 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.

Očekivani izlaz: compliant

Kako se ispravlja

Metod ispravke: Smernica ili zakrpa infrastrukture

Add a condition to each listed statement, e.g. Allow group IAMAdmins to use users in tenancy where target.group.name != 'Administrators' (and likewise for groups).
