Authorizing Cloud Security Infrastructures

Through a case study, we describe the challenges and lessons learned in conducting a FedRAMP-based FISMA Assessment and Authorization (A&A) of a cloud offering. The target cloud service is an Infrastructure As a Service (IaaS) offering that will be made available to federal organizations government-wide through a GSA vehicle.

The major take-ways from this session are as follows:

a)  Gain a better understanding of the challenges in interpreting the NIST SP 800-53 Rev 3 controls within a cloud infrastructure offering;
b)  Understanding ways to delineate the boundaries between the controls (and parts of controls) that are the responsibility of the cloud infrastructure provider versus the end customer who implements information             systems on the cloud infrastructure; and
c)  Understanding the scalability benefits of authorizing the cloud infrastructure once and reusing the A&A artifacts for authorization of multiple customer information systems riding on the same cloud infrastructure.4
