Ensure access to APIs by service principals is restricted

보통레벨 1수동 검토m365

설명

Use a service principal to access Fabric public APIs that include create, read, update, and delete (CRUD) operations, and are protected by a Fabric permission model. To allow an app to use service principal authentication, its service principal must be included in an allowed security group. You can control who can access service principals by creating dedicated security groups and using these groups in other tenant settings. The recommended state is Enabled for a subset of the organization or Disabled. Leaving API access unrestricted increases the attack surface in the event an adversary gains access to a Service Principal. APIs are a feature-rich method for programmatic access to many areas of Power Bi and should be guarded closely.
