 ## Leveraged FedRAMP-Authorized Services
 
-If this system is leveraging the authorization of one or more systems, such as a SaaS running on an IaaS, each leveraged system must be represented within the `system-implementation` assembly. There must be one `leveraged-authorization` assembly and one matching `component` assembly for each leveraged authorization. A leveraged authorization must define a FIPS-199 impact level (low, moderate, or high) that aligns with or exceeds the security sensitivity level of the leveraging system.

There must be one `leveraged-authorization` assembly and one matching `component` assembly for each leveraged authorization. A leveraged authorization must define a FIPS-199 impact level (low, moderate, or high) that matches or exceeds the security sensitivity level of the leveraging system.
 
 The `leveraged-authorization` assembly includes the leveraged system's name, point of contact (POC), and authorization date. The `component` assembly must be linked to the `leveraged-authorization` assembly using a property (prop) field with the name "leveraged-authorization-uuid" and the
 UUID value of its associated `leveraged-authorization` assembly. The `component` assembly enables controls to reference it with the `by-component` responses described in the [*Control Implementation Descriptions*](/documentation/ssp/6-security-controls/#control-implementation-descriptions) section. The "implementation-point" property value must be set to "external". The component assembly must define an `authentication-method` with remarks that explain the method if authentication is used, justify the absence of authentication if not used, or provide an explanation of why authentication is not applicable.
