SOC 2 Trust Services Criteria for Healthcare: Requirements and Compliance Checklist

Overview of SOC 2 Trust Services Criteria

SOC 2 is an independent attestation focused on the Trust Services Criteria (TSC) used to evaluate how your organization safeguards data and how well those controls operate. For healthcare providers, payers, and healthtech vendors that create, receive, maintain, or transmit Personal Health Information (PHI), SOC 2 offers a rigorous, repeatable way to demonstrate due care and HIPAA Compliance alignment.

The five Trust Services Criteria

• Security (Common Criteria): Protection against unauthorized access and disclosure through governance, risk management, and control activities.
• Availability: System uptime and resilience to meet service commitments and recovery objectives.
• Processing Integrity: Complete, valid, accurate, timely, and authorized processing.
• Confidentiality: Protection of information designated as confidential, including PHI and proprietary data.
• Privacy: Collection, use, retention, disclosure, and disposal of personal information consistent with commitments and criteria.

Type I Audit vs. Type II Audit

A Type I Audit reports on the design of controls at a specific point in time—useful to validate your control framework is appropriately designed. A Type II Audit assesses operating effectiveness over a defined period, proving that controls worked consistently in practice. Most healthcare organizations start with Type I, then progress to Type II to satisfy customer and partner expectations.

While SOC 2 is not a legal requirement like HIPAA, it complements HIPAA Compliance by providing externally validated assurance that your security and Data Privacy Controls are both designed and functioning effectively.

Importance of Security Criterion

The Security criterion is foundational; if you select only one TSC, it must be Security. It underpins effective protection of PHI and supports the other criteria, serving as the backbone of your control framework.

• Governance and risk management: Formal policies, risk assessments, and a control matrix aligned to business and patient-safety risks.
• Identity and access management: Least privilege, role-based access, strong authentication, timely provisioning/deprovisioning, and periodic access reviews.
• Data protection: Encryption in transit and at rest, key management, secrets management, and secure data handling procedures.
• Secure change and configuration: Standard builds, change approvals, code review, segregation of duties, and hardened baselines.
• Monitoring and response: Centralized logging, alerting, threat detection, incident response playbooks, and post-incident reviews.
• Resilience: Backup, restore testing, disaster recovery plans, and business continuity aligned to recovery objectives.
• Third-party oversight: Vendor risk management, BAAs where PHI is involved, and review of subservice providers’ SOC reports.

Strong Security controls reduce breach likelihood and impact, directly supporting HIPAA Compliance while maintaining clinical and operational reliability.

Implementing Privacy Controls

SOC 2 Privacy evaluates how you collect, use, retain, disclose, and dispose of personal information. In healthcare, implement Data Privacy Controls that reflect HIPAA’s requirements while honoring patient expectations and contractual commitments.

Practical privacy-by-design steps

• Data mapping and inventories: Document where PHI resides, who accesses it, and why. Maintain authoritative records of processing activities.
• Purpose limitation and minimization: Collect only what you need; design workflows that limit exposure of Personal Health Information.
• Notices and consent: Provide clear privacy notices and capture required authorizations; track revocations and restrictions.
• Access governance: Enforce least privilege, break-glass procedures, and emergency access reviews for clinical scenarios.
• De-identification and masking: Use de-identification, tokenization, or masking in lower environments and analytics.
• Retention and disposal: Enforce retention schedules; automate secure deletion and certificate-backed destruction.
• DLP and monitoring: Detect and prevent unauthorized transmission or storage of PHI; investigate and resolve alerts promptly.
• Individual rights and requests: Enable access, amendments, and accounting of disclosures consistent with policy and law.

These Data Privacy Controls, supported by robust Security and Confidentiality measures, demonstrate responsible stewardship of PHI across its lifecycle.

Mapping HIPAA to SOC 2

Use a control framework to crosswalk HIPAA requirements to the Trust Services Criteria so you can reuse controls and evidence efficiently. The following high-level mappings are common and effective.

• HIPAA Security Rule → SOC 2 Security and Confidentiality: Administrative, physical, and technical safeguards map to governance, access, encryption, logging, and incident response controls.
• HIPAA Privacy Rule → SOC 2 Privacy: Notice, minimum necessary, authorizations, rights, and disclosures align to Privacy criteria and related procedures.
• HIPAA Breach Notification Rule → SOC 2 Security/Privacy: Incident handling, assessment, and notification processes align to detection, evaluation, and communication controls.
• Business Associate Agreements (BAAs) → Vendor Management: Contractual controls, data handling clauses, and right-to-audit align to third-party risk management requirements.

Remember, SOC 2 is an attestation against criteria, while HIPAA Compliance is a legal obligation. A thoughtful mapping ensures coverage but does not create a one-to-one substitute; you should validate both independently.

Preparing for SOC 2 Audits

Preparation is about clear scope, disciplined execution, and proactive evidence management. Decide which TSC to include (Security plus others relevant to your commitments) and define the system boundary that processes PHI.

Readiness checklist

• Define scope: Systems, services, data flows, facilities, and subservice providers handling Personal Health Information.
• Select report type: Use a Type I Audit to validate design, then a Type II Audit for operating effectiveness over time.
• Perform a risk assessment: Tie risks to control objectives and prioritize remediation.
• Document the system description: Services, components, data classifications, commitments, and relevant controls.
• Gap remediation: Implement or mature controls; assign owners, frequencies, and tools.
• Evidence plan: List each control’s evidence, source system, collection cadence, and retention location.
• Auditor selection: Engage an experienced healthcare-focused CPA firm and align on period, sampling, and milestones.
• Run a mock audit: Validate evidence quality, walkthroughs, and sampling readiness before fieldwork.

For Type II, ensure you have consistent control operation for the entire audit period. Automating evidence where possible reduces effort and sampling risk.

Designing Effective Controls

Design principles

• Risk-based and outcome-focused: Start with explicit control objectives tied to patient safety, data protection, and service commitments.
• Clear ownership and accountability: Name control owners and backup roles; define review frequencies and metrics.
• Verifiable and repeatable: Prefer automated controls and machine-generated evidence over manual attestations.
• Defense in depth: Layer preventive, detective, and corrective measures across people, process, and technology.
• Built into workflows: Integrate controls into provisioning, coding, deployment, and clinical operations to reduce friction.

Core control areas for healthcare

• Access management: RBAC, MFA, privileged access, and periodic reviews with revocation SLAs.
• Data protection: Encryption, HSM-based or cloud-native key management, secrets rotation, and certificate lifecycle management.
• Secure SDLC: Threat modeling, SAST/DAST, dependency scanning, code review, and secure deployment pipelines.
• Change and configuration: Infrastructure as code, change approvals, separation of duties, and configuration drift monitoring.
• Monitoring and response: Centralized logging, EDR, SIEM rules, playbooks, tabletop exercises, and after-action reviews.
• Vulnerability and patching: Risk-based SLAs, authenticated scanning, penetration testing, and exception tracking.
• Resilience: Tested backups, restore drills, DR exercises, and RTO/RPO governance.
• Vendor management: Risk tiering, due diligence, BAAs, review of SOC reports, and continuous monitoring.
• Privacy operations: Data mapping, DPIAs/PIAs, minimization, purpose controls, and DLP—your operational Data Privacy Controls.

Adopt a control framework to organize these areas, maintain traceability to risks and commitments, and make auditor walkthroughs straightforward.

Collecting Evidence for Compliance

Reliable evidence proves your controls exist and operate effectively. Plan what to collect, where it resides, and how you will produce it during sampling.

What to collect

• Policies, standards, and sign-offs; training records and acknowledgments.
• Access reviews, user listings, provisioning/deprovisioning tickets, and MFA configurations.
• Encryption settings, key rotation logs, certificate inventories, and storage configurations.
• Change tickets, pull requests, code review records, release approvals, and deployment logs.
• Monitoring evidence: SIEM alerts, incident records, EDR detections, and investigation notes.
• Risk assessments, vulnerability scans, penetration test reports, and remediation tracking.
• Backup job logs, restore test results, DR exercise reports, and recovery metrics.
• Vendor due diligence artifacts, BAAs, and subservice provider SOC reports.
• Privacy artifacts: data maps, DPIAs, de-identification procedures, retention and disposal records.

Quality and handling

• Completeness and accuracy: Evidence should be system-generated where possible and time-stamped.
• Reproducibility: Define repeatable queries and exports; avoid ad-hoc screenshots without context.
• Chain of custody: Store in a controlled repository with access logging and versioning.
• Cadence: Align collection frequency with control operation (daily, weekly, monthly, quarterly, annually).

Compliance Checklist

• Establish governance: charter, roles, control framework, and risk methodology.
• Scope the system and data flows that include Personal Health Information.
• Select TSC, starting with Security; add Availability, Confidentiality, Privacy, and Processing Integrity as needed.
• Decide on Type I Audit timing and plan the subsequent Type II Audit period.
• Close gaps: implement prioritized Security and Data Privacy Controls.
• Build an evidence library with mapped controls and automated collection where feasible.
• Conduct a readiness review and remediate any residual issues before fieldwork.

Key takeaways

Use SOC 2’s Trust Services Criteria as a practical control framework to protect PHI, prove operating effectiveness, and streamline HIPAA-aligned assurance. Start with Security, design controls that are auditable and automated, and maintain a high-quality evidence program to succeed in both Type I and Type II audits.
