These deliverables are the result of a year-long public-private partnership of the Financial and Banking Information Infrastructure Committee (FBIIC) and the FSSCC.

To provide leadership support for this joint effort the U.S. Department of the Treasury established the Cloud Executive Steering Group (CESG) in May 2023 at the direction of the Financial Stability Oversight Council (FSOC), to help close the gaps identified in Treasury’s landmark report on the Financial Services Sector’s Adoption of Cloud Services. The documents published today are intended to arm financial institutions of all sizes with effective practices for secure cloud adoption and operations, and to establish a continuing effort and partnership to begin to address the gaps identified in Treasury’s report, which include:

Establishing a common lexicon that may be used by financial institutions and regulators in discussions regarding cloud.

Enhancing information sharing and coordination for examination of cloud service providers.

Assessing existing authorities for cloud service provider (CSP) oversight.

Establishing best practices for third-party risk associated with cloud service providers, outsourcing, and due diligence processes to increase transparency.

Providing a roadmap for institutions considering comprehensive or hybrid cloud adoption strategies including an update to the Financial Sector’s Cloud Profile.

Improving transparency and monitoring of cloud services for better “security by design.”

“The completion of these two efforts is the culmination of nearly two years of collaboration to further protect our financial system,” said Deputy Secretary of the Treasury, Wally Adeyemo. “The CESG is now a proven model and a new way for the financial services sector to effectively address our most significant cybersecurity challenges.”

“Our financial system is essential infrastructure for the entire economy, and it is deeply reliant on a handful of powerful Big Tech cloud service providers,” said Consumer Financial Protection Bureau Director Rohit Chopra. “Our work will help protect the financial industry from outages and disruption by leveling the playing field between financial firms of all sizes and big cloud service providers.”

“Banks and other financial services firms know they must adapt to new technologies, but many have been uncertain as to how to do so safely and soundly,” said Acting Comptroller of the Currency Michael J. Hsu. “Today’s publications mark a significant step forward by providing a roadmap and helpful resources for banks of all sizes. These documents also clarify cloud service providers’ responsibilities for ensuring a secure and resilient financial system.”

“These documents are an important step forward in the CESG’s effort to make the cloud safer and more resilient within and beyond the financial services industry,” said Bill Demchak, Chairman and CEO, PNC Financial Services Group. “The strong partnership between public- and private-sector leaders allows us to take a more holistic, collaborative approach to defending against evolving threats.”

The CESG model represents an unprecedented level of public-private partnership between Treasury, FBIIC, FSSCC, and cloud service providers (CSPs). Clear explanations for the utility and application of the documents can be found here, on the U.S. Treasury website. The website also includes links to the FSSCC-led outputs so that financial institutions can consult them at any part of their cloud services adoption journey and risk management process.

The FSSCC led the following workstreams:

The Cloud Profile 2.0, authored collectively by the FSSCC Cloud Profile Workstream and the Cyber Risk Institute (CRI), is intended to serve as a cloud security implementation plan for financial institutions of all sizes and functions. The Cloud Profile 2.0 is an extension of the Cybersecurity Profile created by CRI, which is a tool based on the National Institute of Standards and Technology (NIST) Cybersecurity Framework. It provides a framework for both financial institutions and CSPs and will serve as a common tool developed to assist financial institutions in ensuring secure cloud implementation, while allowing the document to evolve as standards change over time.

The Financial Sector Cloud Outsourcing Issues and Considerations document seeks to address challenges raised in the Treasury Cloud Report related to transparency, resource gaps, exposure to operational incidents originating at CSPs, and contract negotiation dynamics. The document, authored collectively by the FSSCC Cloud Outsourcing Issues and Considerations Workstream and the American Bankers Association (ABA) with support from the Securities Industry and Financial Markets Association (SIFMA), identifies a non-exhaustive list of key considerations for developing contractual provisions between financial institutions and CSPs to address risks, regulatory and supervisory compliance expectations when using cloud services. These key considerations should be used as a voluntary reference tool by financial institutions during the contract negotiation phase of onboarding a CSP to appropriately address cybersecurity, resilience, and third party-due diligence expectations, and to enable compliance with growing financial services regulatory requirements and supervisory expectations.

The Transparency and Monitoring for Better “Secure-by-Design” document, authored collectively by the FSSCC Transparency and Monitoring Secure-by-Design Workstream and the Financial Services Information Sharing and Analysis Center (FS-ISAC), is comprised of two outputs for financial institutions with workloads running in CSP environments. The first is a service inter-dependency and resilience model that is a combination of service transparency, architecture best practices, and more detailed information about how a CSP manages the resiliency of its own services. The second proposes packaged cloud configurations that provide baseline security outcomes expected in financial services infrastructure and simplifies financial institutions’ deployment of CSP workloads ("security by default/design" and "one-click" security) that make is easy for financial institutions to quickly turn on secure infrastructure with minimal engineering.

The FBIIC led the following workstreams:

The Cloud Lexicon is a foundational document that captures the most prominent terms used by cloud service providers and financial services sector consumers for a single repository and refence points. The development of the Cloud Lexicon was led by the Office of the Comptroller of the Currency (OCC), and will enable CSPs and financial services sector institutions of all sizes to speak in standardized terms when negotiating contract terms, establishing security schema, and adhering to regulatory standards. The document is based on a review of publications from several standard setting bodies and industry associations, and included interviews and feedback from financial institutions, regulators, and CSPs.

The Coordinated Information Sharing and Examinations Initiative, led by the Consumer Financial Protection Bureau (CFPB), is a collaborative effort that addresses coordination of examinations and information sharing related to CSPs, under the respective agency’s legal authorities. The documented process will support enhanced coordination between agencies to monitor and address risks to both the financial sector and consumers that can arise from financial institutions’ engagement with CSPs.

This collective set of deliverables is intended to highlight opportunities to leverage CESG deliverables into the broader regulatory, oversight, and examination schema, and strengthen the shared responsibility model for cloud services provision in the financial services sector.

Under joint FBIIC and FSSCC leadership, the U.S. Treasury and FSSCC plan to publish additional items related to cloud cyber incident response coordination and cloud concentration risk as they are completed throughout the year.
