How Does the Shared Responsibility Model Impact Rfp Data Governance in a Public Cloud?

Concept

The migration to public cloud infrastructure fundamentally re-calibrates the lines of operational control and accountability for enterprise data. This shift is codified in the shared responsibility model, a foundational concept in cloud computing that delineates the security and operational obligations of the cloud service provider (CSP) versus those of the customer. Your organization’s Request for Proposal (RFP) process, the primary instrument for procuring technology and services, must therefore be re-engineered to operate within this new paradigm.

It is a transition from a model of absolute ownership in an on-premises datacenter to one of precisely defined, shared accountability. The core challenge lies in embedding this division of responsibility deep within the DNA of the RFP, transforming it from a simple procurement document into a sophisticated tool for data governance and risk allocation in a distributed environment.

At its heart, the shared responsibility model is a framework that assigns distinct duties. The CSP is typically responsible for the security of the cloud, which encompasses the physical security of data centers, the underlying network fabric, and the compute, storage, and database services they offer. Conversely, the customer is responsible for security and governance in the cloud. This domain includes the most critical and sensitive assets ▴ your data, identities, application-level controls, client-side data encryption, and network traffic protection.

For all cloud deployment types, the customer always retains full ownership and responsibility for their data and identities. The RFP process, therefore, becomes the primary mechanism through which an organization can formally assess a CSP’s capabilities to secure their part of the bargain while simultaneously defining the internal controls and processes required to manage the customer’s side of the ledger.

The shared responsibility model reframes data governance not as a transfer of risk to the cloud provider, but as a re-allocation of specific duties that must be meticulously managed through the RFP process.

This dynamic profoundly impacts RFP data governance by forcing a granular, evidence-based approach to vendor evaluation. A traditional RFP might have asked broad questions about a vendor’s security posture. An RFP designed for the public cloud must ask surgical questions that map directly to the shared responsibility model. It must probe a CSP’s specific controls for infrastructure security, their compliance with global and regional regulations, and their processes for incident response within their domain.

Simultaneously, the RFP process must trigger an internal conversation about the organization’s own data governance maturity. It compels the organization to classify its data, define access policies, and establish the technical and administrative controls it will be responsible for implementing and managing. The RFP ceases to be merely a document for external evaluation and becomes a catalyst for internal governance transformation.

Strategy

Adapting RFP data governance to the public cloud requires a strategic framework that is both comprehensive and flexible. The central pillar of this strategy is the explicit integration of the shared responsibility model into every phase of the procurement lifecycle. This involves moving beyond generalized security inquiries to a detailed, matrix-based assessment that aligns data governance requirements with the specific cloud service model being procured ▴ whether Infrastructure as a Service (IaaS), Platform as a Service (PaaS), or Software as a Service (SaaS). Each model shifts the line of demarcation for responsibility, and the RFP must reflect this nuance with precision.

Mapping Governance to Service Models

The initial strategic step is to deconstruct data governance into its core components and map them against the responsibilities inherent in each cloud service model. A successful strategy recognizes that responsibilities for controls like network configuration, operating system hardening, and application security change dramatically between IaaS, PaaS, and SaaS. For instance, in an IaaS model, the customer retains control over the operating system, middleware, and applications, making them responsible for a significant portion of the security stack. In a SaaS model, the provider manages almost the entire stack, leaving the customer with primary responsibility for data governance, user access, and endpoint security.

Your RFP strategy must operationalize this understanding. This means developing specific sections and questions in the RFP document that are tailored to the service model. For an IaaS procurement, the RFP should contain detailed questions about the CSP’s hypervisor security, network isolation capabilities, and physical infrastructure controls. For a SaaS RFP, the focus shifts to the provider’s application-level security, data encryption capabilities (both in-transit and at-rest), identity and access management integrations, and their own internal data handling policies.

A robust cloud procurement strategy uses the RFP to create a clear, contractual understanding of which party is responsible for each specific data governance control.

A Tiered Framework for RFP Questions

A sophisticated strategy involves creating a tiered system of inquiry within the RFP. This moves from broad policy questions to specific, evidence-based validation requests. This structured approach ensures that a CSP’s responses can be evaluated systematically and consistently.

• Tier 1 ▴ Policy and Compliance. This section of the RFP focuses on the CSP’s high-level governance posture. It should request documentation of their security policies, their compliance with international standards (like ISO 27001, SOC 2), and their adherence to industry-specific regulations (like HIPAA, PCI DSS).
• Tier 2 ▴ Control Implementation. Here, the questions become more granular. The RFP should ask the CSP to describe the specific technical controls they have implemented to fulfill their responsibilities. For example, instead of asking “Do you secure your servers?”, a Tier 2 question would be “Describe the processes and technologies used for vulnerability scanning, patch management, and configuration hardening on the physical and virtual hosts supporting your service.”
• Tier 3 ▴ Evidence and Auditing. This is the most critical tier for validating a CSP’s claims. The RFP should require potential vendors to provide third-party audit reports, penetration testing results (sanitized, if necessary), and certifications. It should also probe their willingness to accommodate customer-initiated audits or provide access to logging and monitoring data that allows the customer to verify security and compliance on an ongoing basis.

Comparative Responsibility Matrix

To provide clarity for both internal stakeholders and responding vendors, a powerful strategic tool is the inclusion of a responsibility matrix directly within the RFP. This table explicitly defines the expected division of labor for key data governance domains.

Incorporating such a matrix into the RFP serves two purposes. It forces the organization to think critically about its own responsibilities before issuing the request. Secondly, it provides a clear and unambiguous framework for CSPs to structure their responses, ensuring that proposals are directly comparable and address the specific delineations of responsibility the organization expects to enforce.

Execution

The execution phase translates the strategic framework for cloud-aware RFP data governance into a set of precise, operational procedures and artifacts. This is where high-level strategy is converted into the granular detail required to effectively evaluate, select, and manage a cloud service provider. The execution hinges on embedding the principles of shared responsibility into the very fabric of the RFP document and the subsequent vendor evaluation process. This requires a meticulous approach to drafting questions, defining evaluation criteria, and establishing post-award governance mechanisms.

Crafting the Cloud-Native RFP Document

The RFP document itself is the primary tool of execution. It must be structured to elicit specific, evidence-based information about how a CSP manages its responsibilities and how its platform enables the customer to manage theirs. This involves moving away from generic questionnaires to a purpose-built document.

Checklist for Core RFP Sections

1. Introduction and Governance Framework.
   • State the organization’s commitment to a shared responsibility model.
   • Include the Data Governance Responsibility Matrix (as detailed in the Strategy section) to set clear expectations from the outset.
   • Define key terms (e.g. “Customer Data,” “Sensitive Information”) as they will be used throughout the document.
2. CSP Security and Compliance.
   • Request a complete list of all current security and privacy certifications (e.g. ISO 27001, SOC 2 Type II, FedRAMP).
   • Require the CSP to provide their own responsibility matrix or a direct response to the one provided.
   • Ask for details on their data center security, including physical access controls, environmental protections, and staff security screening.
3. Customer-Enablement Controls.
   • This section is critical. For each governance domain assigned to the customer, the RFP must ask how the CSP’s platform facilitates the customer’s execution of their responsibilities.
   • Data Protection ▴ What tools are provided for data encryption at rest and in transit? Does the customer have the option to manage their own encryption keys (BYOK/HYOK)?
   • Identity and Access Management ▴ Describe the platform’s IAM capabilities. Does it support integration with the customer’s existing identity provider (e.g. Active Directory, Okta)? How granular are the role-based access controls (RBAC)?
   • Logging and Monitoring ▴ What level of logging is available to the customer? Can logs be exported to a customer-owned SIEM? Do the logs provide sufficient detail to investigate a security incident?
4. Incident Response and Data Breach Notification.
   • Demand a detailed description of the CSP’s incident response plan.
   • Specify the required timeframe for notifying the customer of a security incident affecting their data or services. This must align with the customer’s own regulatory and contractual obligations.
   • Clarify the roles and responsibilities during a security event. Who is responsible for investigation, containment, and remediation at each layer of the technology stack?

Quantitative Evaluation and Scoring

A subjective evaluation of RFP responses is insufficient. A quantitative scoring model must be developed to ensure a rigorous, defensible, and repeatable selection process. This model should assign weights to different sections of the RFP based on the organization’s risk priorities. For example, an organization handling sensitive health information might place a higher weight on sections related to data encryption and regulatory compliance than one handling public marketing data.

A well-defined scoring matrix transforms vendor evaluation from an art into a science, enabling a clear, data-driven selection decision.

The scoring matrix should break down each major section into specific, measurable criteria. Each criterion is then scored, and the weighted scores are aggregated to produce a final ranking of the vendors.

Post-Award Governance and Continuous Verification

The execution of data governance does not end with the signing of a contract. The RFP and the vendor’s responses become the foundation of an ongoing governance and verification program. The contractual agreement must incorporate key provisions from the RFP, including the responsibility matrix, service level agreements (SLAs) for security, and breach notification requirements.

Regular audits, both of the CSP’s compliance and of the organization’s own adherence to its responsibilities, are essential. This continuous verification loop ensures that the data governance framework established during the RFP process remains effective throughout the lifecycle of the cloud service.

Reflection

The integration of the shared responsibility model into the RFP process represents a fundamental evolution in how organizations approach data governance. It moves the discipline from a posture of centralized command to one of distributed, federated control. The framework and procedures outlined here provide a system for managing this distribution, but the ultimate effectiveness of this system rests on a cultural shift. It requires viewing data governance not as a static set of rules enforced by a single department, but as a dynamic, living process that is co-owned by the organization and its cloud partners.

The true measure of success is the extent to which this shared understanding of responsibility permeates every decision related to cloud services. Does the application development team understand which security controls they are accountable for deploying? Does the legal team understand the precise breach notification timeline they have negotiated?

Does the procurement team see the RFP as the first and most critical step in a long-term governance partnership? The documents, matrices, and checklists are the necessary architecture, but the operational discipline to inhabit that architecture is what builds a truly resilient and secure data ecosystem in the public cloud.
