Secure Cloud Business Applications (SCuBA) Project

Secure Cloud Business Applications (SCuBA)


The Secure Cloud Business Applications (SCuBA) project provides guidance and capabilities to secure agencies’ cloud business application environments and protect federal information that is created, accessed, shared and stored in those environments.

SCuBA will help secure Federal Civilian Executive Branch (FCEB) information assets stored within cloud environments through consistent, effective, modern, and manageable security configurations.

Current Status

CISA released updates to the Microsoft 365 and Google Workspace Secure Configuration Baselines on May 22, 2024.

The Hybrid Identity Solutions Guidance document was finalized and published March 12, 2024. 

The SCuBA Technical Reference Architecture and extensible Visibility Reference Framework Guidebook were finalized and published June 27, 2023. 


CISA requested public comment on the Technical Reference Architecture (TRA) and extensible Visibility Reference Framework (eVRF) in the first phase of the SCuBA project to ensure our guidance enables the best flexibility to keep pace with evolving technologies and capabilities and protect the federal enterprise.

CISA's intent is to properly address cybersecurity and visibility gaps within cloud-based business applications that have hampered our collective ability to adequately understand and manage cyber risk across the Federal and IT enterprise.

CISA has now finalized the TRA and eVRF documents.


The TRA is a security guide that agencies can use to adopt technology for cloud deployment, adaptable solutions, secure architecture and zero trust frameworks.

The eVRF Guidebook provides an overview of the eVRF framework, which enables organizations to identify visibility data that can be used to mitigate threats, understand the extent to which specific products and services provide that visibility data, and identify potential visibility gaps.  

The eVRF consists of a guidance document, two product-specific workbook overviews, and two product-specific workbooks.
