Cloud Providers and HIPAA: Risk Assessment Guide
Post Summary
Healthcare organizations increasingly rely on cloud service providers (CSPs) to manage sensitive patient data, but this shift introduces complex compliance challenges under HIPAA. Here's what you need to know:
- HIPAA Compliance in the Cloud: Both healthcare organizations and CSPs share responsibilities for securing electronic protected health information (ePHI). Risk assessments are mandatory to identify potential threats and vulnerabilities.
- Business Associate Agreements (BAAs): A BAA is required before storing or processing ePHI in the cloud. Failure to secure a BAA can lead to severe penalties.
- Data Flow Mapping: Identify where ePHI resides, how it moves, and who has access. This step is critical for effective risk management.
- Risk Mitigation: Address risks with encryption, access controls, and incident response plans. Use tools like Cloud Security Posture Management (CSPM) to identify and resolve vulnerabilities.
- Continuous Monitoring: Regularly review system activity, access controls, and vendor compliance to maintain security and meet HIPAA obligations.
HIPAA compliance in cloud environments requires ongoing risk assessments, clear documentation, and close collaboration with CSPs. This guide outlines practical steps to safeguard ePHI and avoid costly violations.

HIPAA Requirements for Cloud Environments
When healthcare organizations store electronic protected health information (ePHI) in the cloud, both the organization and its cloud service provider (CSP) share responsibilities under HIPAA. Understanding how the HIPAA Security Rule applies in cloud environments is essential for conducting thorough risk assessments and avoiding compliance issues. Let’s break down these requirements and how they apply to cloud-based systems.
HIPAA Security Rule Provisions
The HIPAA Security Rule outlines specific obligations for both healthcare organizations and CSPs. Under 45 CFR 164.308(a)(ii)(A), both parties are required to perform risk analyses to identify potential threats and vulnerabilities that could compromise the confidentiality, integrity, or availability of ePHI. After identifying risks, 45 CFR 164.308(a)(ii)(B) mandates the implementation of appropriate security measures to address those risks.
CSPs must also have robust incident response protocols in place. According to 45 CFR 164.308(a)(ii), they are required to detect, respond to, mitigate, and document any known or suspected security incidents. This includes maintaining detailed records of such incidents and the steps taken to resolve them.
It’s important to note that CSPs are directly liable under HIPAA, regardless of whether a Business Associate Agreement (BAA) is in place. The Department of Health and Human Services (HHS) clarifies:
A CSP is not responsible for the compliance failures that are attributable solely to the actions or inactions of the customer, as determined by the facts and circumstances of the particular case.
Even if a CSP offers "no-view" services (where only encrypted ePHI is stored), they must still implement safeguards to secure administrative tools and ensure system integrity.
Business Associate Agreements (BAAs)
In addition to technical safeguards, establishing a BAA is a legal requirement before any ePHI is processed or stored in the cloud. A BAA formalizes how security responsibilities are divided between the healthcare organization and the CSP. Failure to execute a BAA before storing ePHI has led to penalties enforced by the Office for Civil Rights.
A well-defined BAA should address key areas such as:
- Data access controls: Who can access ePHI and under what circumstances.
- Backup and recovery: Procedures to ensure data is secure and recoverable.
- Breach notification: Timelines and responsibilities for reporting security incidents.
- Data management post-contract: Under 45 CFR 164.504(e)(ii)(J), CSPs must return or destroy all PHI at the end of the contract, where feasible.
Service Level Agreements (SLAs) must also align with the terms of the BAA. If an SLA includes terms that conflict with HIPAA - such as limiting access to ePHI or restricting audit rights - it creates compliance risks. Additionally, breach notification procedures must comply with 45 CFR 164.410. In cases of a breach involving unsecured PHI, CSPs are required to notify the healthcare organization. They may only avoid penalties if they correct the issue within 30 days of discovery and if the breach was not caused by willful neglect.
Mapping ePHI Across Cloud Infrastructure
To effectively assess risks, you first need to pinpoint exactly where your electronic protected health information (ePHI) resides. This involves creating a detailed map of every location where ePHI is created, received, stored, or transmitted within your cloud environment. Without this full visibility, your risk assessments will always be incomplete.
In 2025, the healthcare sector experienced over 311 data breaches, impacting more than 23 million individuals. Alarmingly, nearly 80% of these breaches stemmed from hacking and IT-related attacks [4]. Many of these incidents could have been avoided with better insight into where ePHI was stored. Mapping your data flows isn’t just about meeting compliance requirements - it’s a critical step in protecting sensitive information from unauthorized access and data loss.
Data Flow Mapping and System Inventory
Start by documenting the entire lifecycle of ePHI across your cloud infrastructure. Track data from the moment a patient interacts with a system, such as logging into a portal, through processes like billing, analytics, and eventual archival or deletion. Your inventory should encompass all cloud services, regions, and accounts, including production environments, development and testing systems, backups, database replicas, snapshots, and cached data [1].
One major challenge is uncovering unsanctioned cloud services - tools or platforms adopted without IT approval. For instance, a marketing team might use an unapproved analytics tool, or a clinic might rely on a scheduling app that isn’t vetted, potentially exposing ePHI without adequate safeguards [4].
Your mapping should also account for encryption keys, access controls, and API connections to ensure thorough HIPAA risk assessments [1]. Key questions to address include: Who has access to the data? How is it encrypted both during transmission and at rest? What APIs connect your systems? For example, if ePHI flows from an EHR system to a billing processor via an API, you must document both endpoints, the transmission method, and any intermediary systems.
Assigning a Privacy Officer to lead this initiative can help ensure a comprehensive approach. This role involves conducting a gap analysis across departments to identify workflows involving ePHI, whether internal or with external partners [3]. Include metadata in your asset catalog - like data ownership, classification, and deployment location - to simplify audits.
HIPAA mandates preserving risk analysis and mapping documentation for at least six years [1][4]. Treat your data flow maps as living documents that adapt as your infrastructure changes. Revisit them annually or whenever significant updates occur, such as migrating workloads to a new cloud region or adopting new services [1].
Classifying ePHI by Sensitivity and Residency
Not all ePHI carries the same level of risk. For instance, while a patient’s name and appointment date are sensitive, full medical records, mental health notes, or substance abuse treatment details require even stricter safeguards. Classify ePHI based on sensitivity to prioritize risk management efforts [1][4]. High-sensitivity data might call for stronger encryption, stricter access controls, or more frequent monitoring.
Data residency is another crucial factor. Some states have specific rules about where health data can be stored. Make sure to document the geographic location of every data store, including backups and replicas, to ensure compliance with these regulations [1].
When mapping cloud data, distinguish between controls managed by you and those handled by your cloud service provider (CSP) [1]. While CSPs often manage physical security and infrastructure, you are responsible for setting up access controls, encryption, and monitoring.
Integrated risk management tools, like Censinet RiskOps™, can simplify these efforts. These platforms help centralize ePHI mapping, automate inventory updates, and maintain dynamic documentation that evolves with your cloud infrastructure.
Proposed updates to the 2025 HIPAA Security Rule suggest moving from "addressable" safeguards to mandatory, standardized requirements. These changes may include stricter expectations for ePHI system inventories [4]. Organizations with accurate and up-to-date data maps will be better equipped to meet these new standards. As the SaltyCloud Research Team emphasizes:
The HIPAA Security Rule is not a checkbox. It is the foundation of every effective HIPAA security program [4].
Identifying Threats and Vulnerabilities
Once you've mapped out your ePHI, the next step is to identify potential threats that could exploit weaknesses in your cloud infrastructure. This process is crucial for meeting HIPAA's requirement to evaluate and address risks to ePHI. As the HHS Office for Civil Rights explains:
Risk can be understood as a function of 1) the likelihood of a given threat triggering or exploiting a particular vulnerability, and 2) the resulting impact on the organization [6].
Cloud environments are exposed to unique risks. Common issues include misconfigured storage buckets and Virtual Private Clouds (VPCs), over-permissive access roles, insecure APIs, privilege misuse, and data exfiltration [5][1]. Human-related threats range from intentional actions like network attacks and unauthorized access to unintentional errors such as accidental deletions or data entry mistakes [6]. Even environmental factors - like natural disasters or power outages - can disrupt data availability [6].
The numbers paint a concerning picture: recent breaches have exposed millions of records, with business associates being responsible for about 40% of HIPAA breaches involving over 500 records [3]. Penalties for non-compliance can climb to an annual cap of $1.5 million per category [5].
To combat these threats, tools like Cloud Security Posture Management (CSPM) and Cloud-Native Application Protection Platforms (CNAPP) can help identify issues like configuration drift, open ports, and unencrypted data [5]. Pair these tools with practices like audit log reviews, MFA monitoring, and runtime anomaly detection to catch both technical and human errors. For environmental risks, examine your cloud provider's Service Level Agreements (SLAs) and SOC 2 reports to gauge their resilience [5][6]. Once threats are identified, a detailed analysis is necessary to assess their likelihood and potential impact.
Risk Analysis Methodologies
A structured approach ensures your risk assessment is both thorough and defensible. NIST SP 800-30 is widely regarded as the standard for this process. It involves identifying threats and vulnerabilities, assessing their likelihood and impact, and scoring each risk [6][4]. This method helps prioritize risks based on their potential consequences.
For smaller organizations, the HHS/ONC Security Risk Assessment (SRA) Tool (v3.6) offers a helpful alternative. Updated for 2025/2026, it guides users through threat and vulnerability assessments and aligns its risk scale with NIST's, replacing "medium" with "moderate" for consistency [2]. Whether you choose NIST or the SRA Tool, the goal remains the same: pair threats with vulnerabilities, estimate their likelihood, and measure the potential impact on patient safety, business continuity, legal compliance, and the confidentiality, integrity, and availability of ePHI.
Setting clear risk tolerance and scoring criteria upfront is critical. For instance, decide if a misconfigured API exposing appointment schedules should be rated as a "moderate" or "high" impact based on your organization's risk appetite and the data's sensitivity. This clarity ensures your findings are auditable and repeatable, particularly during HIPAA inspections.
Platforms like Censinet RiskOps™ can simplify this process by automating risk data collection and offering real-time insights into cyber risks across your cloud environment. These tools help you move beyond manual spreadsheets, centralizing vulnerability tracking and enabling dynamic, collaborative risk assessments. Documenting risks as they are identified ensures continuous monitoring and follow-up.
Documenting Risks in a Risk Register
A risk register is essential for keeping track of identified threats and their mitigation strategies. It should include details such as the threat-vulnerability pair, affected cloud services, risk owners, remediation deadlines, and the chosen mitigation strategy - whether to accept, avoid, transfer, or reduce the risk [6]. This document serves as evidence of your disciplined risk management process, especially during HIPAA audits.
Keep your risk register dynamic. Update it whenever new cloud services are introduced, workloads are migrated, vendors are added, or security incidents occur [1][4]. Feed high-priority risks directly into engineering workflows and change control systems to ensure they are actively addressed, not just documented. Focus on gaps that could compromise ePHI or critical business services - these should take precedence.
Think of your risk register as a living document, much like your data flow maps. While annual reviews are the minimum, event-driven updates after major changes or incidents ensure your assessments remain relevant. As Steve Alder, Editor-in-Chief of The HIPAA Journal, puts it:
A HIPAA risk assessment assesses threats to the privacy and security of PHI, the likelihood of a threat occurring, and the potential impact of each threat so it is possible to determine whether existing policies, procedures, and security mechanisms are adequate [3].
Mitigating Risks and Implementing Controls
Turn your identified risks into actionable plans that safeguard ePHI while ensuring smooth cloud operations. This section bridges the gap between your risk assessment findings and the compliance goals highlighted earlier.
Developing Risk Treatment Plans
A risk treatment plan takes your risk register and converts it into a set of specific actions with assigned responsibilities and deadlines. Start by prioritizing risks based on their likelihood and potential impact on areas like patient safety, business continuity, and HIPAA compliance. For example, high-risk issues such as an exposed S3 bucket should be addressed immediately, while lower-priority risks can be monitored over time.
Each risk should have a clear owner, defined actions, and a timeline. For instance, if an S3 bucket is found without proper encryption, you might block public access and enable AES-256 server-side encryption as a first step. Then, in Week 1, conduct an access review and implement role-based access control (RBAC). By Week 2, perform a penetration test and document the findings in your risk register. This structured approach not only reduces the likelihood of breaches but also provides essential documentation for audits [7][8].
Your strategies for addressing risks can include:
- Mitigation: Reduce risk by implementing controls like encryption.
- Acceptance: Monitor low-level risks regularly without immediate action.
- Transfer: Shift responsibility through Business Associate Agreements (BAAs) or cyber insurance.
- Avoidance: Eliminate risk by not using non-compliant features.
For example, mitigate API vulnerabilities by enabling multi-factor authentication (MFA), accept minor configuration risks with periodic audits, transfer liability via your cloud provider’s BAA, or avoid using unencrypted storage solutions altogether.
Track your progress with measurable goals, such as reducing critical vulnerabilities to below 5%, and conduct monthly audit log reviews. Enforce MFA across all administrative accounts and ensure regular reviews - whether annual assessments or checks after significant changes - to keep your controls aligned with HIPAA requirements [7][5][9]. Tools like Censinet RiskOps™ can simplify this process by automating risk data collection, centralizing vulnerability tracking, and enabling real-time collaboration between compliance and IT teams.
With detailed treatment plans established, the next step is ensuring they’re supported by robust technical and administrative safeguards.
Implementing Technical and Administrative Safeguards
Technical and administrative safeguards bring your risk treatment plans to life, ensuring ongoing HIPAA compliance.
Technical safeguards are the backbone of ePHI protection in cloud environments:
- Use encryption for data at rest and in transit.
- Implement RBAC and MFA to restrict access to authorized personnel only.
- Employ network segmentation to separate ePHI workloads from less secure systems.
- Utilize logging and monitoring tools like AWS CloudTrail or Azure Monitor to create audit trails and detect unauthorized access attempts [7][8][5].
Administrative safeguards support these technical controls:
- Draft policies detailing how staff should handle PHI in cloud environments.
- Train employees on phishing-resistant MFA and incident reporting procedures.
- Conduct vendor evaluations using questionnaires and BAA reviews to confirm compliance with HIPAA standards.
These administrative measures reinforce technical controls. For instance, aligning least-privilege access policies with your Identity and Access Management (IAM) configurations ensures consistency between policy and practice [8][5][9].
Incident response planning is another essential component. Develop cloud-specific breach response plans that define roles (such as an incident commander), establish communication protocols (including notifying HHS within 60 days of a breach), and outline data recovery processes that align with your cloud provider’s Recovery Point Objectives (RPO) and Recovery Time Objectives (RTO). Tabletop exercises can help your team rehearse these plans and respond effectively to incidents [7][8][10]. Keep in mind that under the shared responsibility model, your cloud provider secures the infrastructure, but you are responsible for managing data, access controls, and configurations [11].
Regular validation of your controls is key. Use vulnerability scanning, penetration testing, and other testing methods to ensure everything is functioning as intended. Document your findings with evidence like MFA enforcement logs, policy updates, and third-party attestations (e.g., SOC 2 reports). This documentation not only supports HIPAA compliance during OCR audits but also demonstrates your commitment to protecting patient data [7][5][9]. With a proposed 2025 HIPAA rule requiring documented evaluations of business associates, maintaining detailed records of your risk management efforts is more critical than ever [9].
Evaluating Cloud Providers and Third-Party Risks
The security practices of your cloud provider play a direct role in maintaining HIPAA compliance, but you can't simply take their word for it - independent verification is essential. In 2023, 96% of healthcare organizations experienced data breaches, with third parties contributing to 57% of these incidents [10]. This highlights the importance of thoroughly evaluating vendors. Under the shared responsibility model, cloud providers handle the security of their infrastructure, but you're still accountable for safeguarding your data, managing access, and ensuring compliance in areas like encryption, configurations, and monitoring. A detailed evaluation lays the foundation for effective risk management and ongoing monitoring.
Reviewing Cloud Provider Certifications
Start by requesting up-to-date certifications that confirm your provider's security measures. SOC 2 Type II reports are especially helpful since they assess security, confidentiality, and privacy controls over a 6–12 month period - key aspects for HIPAA compliance. Look for reports with unqualified opinions and no significant weaknesses in areas like encryption, access control, incident response, and subprocessor management.
ISO 27001 certifications, backed by audit summaries, demonstrate that the provider has a solid information security management system in place. For healthcare-specific needs, HITRUST CSF certifications are highly relevant, as they combine elements of HIPAA, SOC 2, and ISO 27001 into a single framework. Reputable providers also offer HIPAA-compliant services through Business Associate Agreements (BAAs).
Make it a point to review these certifications annually and compare the findings with your risk register. If the technical details feel overwhelming, you might want to bring in third-party experts or use tools like Censinet RiskOps™ to simplify vendor evaluations and cybersecurity assessments. Remember, certifications are just the starting point - regular reviews and integration with your risk management processes are essential for maintaining compliance.
Managing Subprocessor and Fourth-Party Risks
Cloud providers often rely on subprocessors for tasks like infrastructure, logging, and backups. These fourth-party vendors can introduce indirect risks to your electronic protected health information (ePHI), and it's your responsibility to manage these risks effectively. Request a full list of subprocessors from your provider, confirm that each one is bound by a BAA, and ensure you’re notified of any changes. You should also have the option to approve new subprocessors before they handle your ePHI.
To stay on top of things, map out the entire vendor chain to understand how data flows and use security questionnaires to verify subprocessor controls. Pay close attention to areas like encryption, access management, and breach notification procedures. Clearly define responsibilities for critical functions such as key management, audit logging, and disaster recovery. Also, confirm that your provider has documented procedures for securely destroying data when subprocessor contracts end.
Conduct quarterly reviews to monitor changes and identify emerging risks. Tabletop exercises that simulate fourth-party breach scenarios can also help you test your incident response plans and identify any weaknesses in your vendor management strategy. Keeping subprocessors in check strengthens your overall cloud security approach and supports a well-rounded risk management framework.
Continuous Monitoring and Documentation
After addressing risk treatment and evaluating third-party compliance, maintaining HIPAA compliance requires ongoing monitoring and meticulous documentation. This isn’t a one-and-done process - HIPAA compliance involves a cycle of continuous risk reassessment and thorough record-keeping. Your cloud risk assessment must adapt as your infrastructure evolves, threats change, and regulations update. Organizations are required to reassess risks at least annually or whenever significant changes occur, such as architectural updates, new services, or security incidents [1]. Between these formal evaluations, continuous monitoring helps detect issues like configuration drift, unauthorized access attempts, and new vulnerabilities before they result in breaches or compliance failures.
The following sections break down how to effectively monitor your environment and document your compliance activities to stay ahead of potential risks.
Implementing Continuous Monitoring Systems
Continuous monitoring serves as the foundation for maintaining the safeguards you’ve put in place. Real-time monitoring systems are essential for identifying anomalies and ensuring compliance. Key measures include activity logging, automated data classification, and regular application of patches [8]. While cloud service providers often offer features like encryption (for both data in transit and at rest), access controls, and activity tracking, it’s your responsibility to actively review and analyze this data.
Plan for regular reviews of system activity, such as audit logs and access reports [1]. Pay special attention to access control mechanisms, including single sign-on combined with multi-factor authentication, privileged access management, and break-glass procedures with enhanced oversight. Conduct periodic access certifications across applications, databases, and cloud environments, and document approvals for exceptions or time-limited elevated access [1]. Additionally, monitor and log data transfers, particularly when it involves snapshot exports or removable media, to ensure you have visibility into how electronic protected health information (ePHI) moves within your system.
Tools like Censinet RiskOps™ can simplify this process by consolidating monitoring data, automating risk assessments, and providing a centralized dashboard to track compliance across your cloud infrastructure. Integrating these monitoring systems with incident response workflows ensures quicker detection and resolution of potential ePHI breaches [1].
Documenting Risk Management Activities
Thorough documentation is critical for demonstrating compliance during audits or investigations by the Department of Health and Human Services (HHS). Your HIPAA risk assessment findings should be supported by clear evidence, including policies, audit logs, training records, incident response plans, and third-party attestations [9].
Maintain a centralized risk register that is continuously updated with your latest mitigation measures [11][9]. Each safeguard should be documented with proof of its effectiveness, and the risk register should link directly to corresponding controls and verification tests [1]. This allows you to track how identified risks are addressed through specific controls and monitor their ongoing status and any residual risks [1]. Such documentation creates a detailed audit trail, showing how infrastructure changes were assessed and what actions were taken.
For incident response, ensure your documentation includes chain-of-custody records and evidence artifacts to preserve the integrity of your audit trail. Record all steps of the incident lifecycle - triage, investigation, containment, eradication, and recovery - along with ticketing and communication logs for any potential ePHI breaches [1]. Additionally, regularly test your backup and disaster recovery plans, documenting the outcomes, identifying gaps, and noting corrective actions taken [1]. This level of detail not only proves your ability to respond to incidents but also highlights your commitment to learning from them and improving your processes - an essential aspect of maintaining continuous compliance.
Conclusion
This guide has walked through the essential steps for managing risks, from identifying vulnerabilities to implementing continuous monitoring. Conducting mandatory HIPAA-compliant risk assessments is critical, especially when breaches can cost healthcare organizations an average of $10.1 million in 2024. These assessments also help uncover 80–90% of common vulnerabilities[13], making them a cornerstone of any secure cloud environment.
To maintain HIPAA compliance, healthcare organizations need a combination of technical and administrative safeguards. Technical measures like encryption and multi-factor authentication should work in tandem with administrative actions such as documented policies, regular audits, penetration testing, and tabletop exercises to test response plans[11][9]. Even with a HIPAA-compliant cloud infrastructure, organizations must actively manage their configurations and monitor their environments under the shared responsibility model[11][12].
Managing subprocessors, tracking controls, and reassessing risks after changes can be overwhelming for even the most experienced teams. Tools like Censinet RiskOps™ help simplify this process by automating risk assessments, centralizing monitoring data, and fostering collaboration between healthcare organizations and vendors through a dedicated risk exchange. Automating these processes reduces manual effort, saves time, and helps security teams manage third-party risks more efficiently.
Risk management doesn’t stop after the initial assessment. Update your risk register annually or after significant changes, such as adopting new cloud services, modifying your architecture, or addressing security incidents. A dynamic risk register with clear ownership, timelines, and documented safeguards is essential[11][9]. This ongoing cycle of assessment, monitoring, and documentation not only ensures compliance with HHS but also strengthens patient data protection.
FAQs
What cloud services are considered ePHI exposure under HIPAA?
Cloud services that manage or store electronic Protected Health Information (ePHI) - like cloud storage, computing platforms, or applications - can increase the risk of ePHI exposure under HIPAA if not handled correctly. These risks often stem from inadequate security measures, lack of encryption, or improper configurations that fail to align with HIPAA standards. Meeting compliance requirements is crucial to safeguarding patient data and adhering to regulatory obligations.
