This curriculum spans the equivalent of a multi-workshop program, covering governance, risk, access, infrastructure, incident response, third-party management, monitoring, privacy engineering, compliance alignment, and maturity assessment across complex healthcare environments.

Module 1: Establishing Governance Frameworks Aligned with ISO 27799

  • Selecting an appropriate governance structure (centralized, decentralized, or hybrid) based on organizational size and healthcare regulatory complexity.
  • Defining roles and responsibilities for data stewards, custodians, and privacy officers within clinical and administrative units.
  • Mapping ISO 27799 control objectives to existing healthcare compliance mandates such as HIPAA, GDPR, or PIPEDA.
  • Integrating clinical leadership into governance committees to ensure medical workflow implications are evaluated.
  • Establishing escalation paths for data breach incidents that bypass operational silos and reach executive oversight.
  • Developing a formal charter for the data governance board with authority to enforce policy adherence across departments.
  • Aligning governance timelines with audit cycles from external regulators and accreditation bodies like Joint Commission.
  • Documenting decision rationales for control exceptions to satisfy future forensic or regulatory review.

Module 2: Risk Assessment Methodologies Specific to Health Information

  • Conducting asset inventories that include legacy medical devices with limited patching capabilities.
  • Assigning sensitivity levels to data types such as genomic records, mental health notes, and billing information.
  • Assessing third-party risks for cloud-based EHR systems with shared responsibility models.
  • Quantifying risk exposure using likelihood-impact matrices calibrated to healthcare breach cost benchmarks.
  • Identifying high-risk interfaces such as patient portals, medical IoT, and API gateways to external labs.
  • Updating risk registers after changes in clinical operations, such as telehealth expansion or new device deployment.
  • Choosing between qualitative and quantitative risk analysis based on data availability and stakeholder requirements.
  • Validating risk treatment plans with clinical IT teams to ensure technical feasibility without disrupting care delivery.

Module 3: Designing Access Control Policies for Clinical Environments

  • Implementing role-based access control (RBAC) with role definitions that reflect actual clinical workflows (e.g., attending vs. resident).
  • Configuring just-in-time (JIT) access for temporary staff and locum physicians with time-bound entitlements.
  • Enforcing separation of duties between billing, clinical documentation, and administrative functions.
  • Managing emergency override access in critical care scenarios while ensuring audit trail completeness.
  • Integrating access reviews with HR offboarding processes to deactivate credentials within 24 hours of staff departure.
  • Monitoring for privilege creep among long-tenured clinicians who accumulate excessive access rights.
  • Applying attribute-based access control (ABAC) for dynamic access decisions based on patient consent status or location.
  • Testing access control logic during EHR upgrades to prevent unintended privilege escalation.

Module 4: Securing Health Data Across Hybrid IT Environments

  • Classifying data residing in on-premise servers, private clouds, and SaaS platforms to apply consistent protection rules.
  • Deploying encryption for data at rest in databases containing protected health information (PHI), including key management strategies.
  • Implementing TLS 1.3 with mutual authentication for data in transit between hospital systems and remote clinics.
  • Configuring data loss prevention (DLP) tools to detect unauthorized transfers of patient lists or diagnostic images.
  • Securing backup tapes and cloud snapshots with access logging and retention policies aligned with legal hold requirements.
  • Hardening endpoints used by mobile clinicians, including tablets and laptops, with full-disk encryption and remote wipe.
  • Managing encryption key lifecycle in accordance with NIST SP 800-57, including rotation and archival procedures.
  • Validating cloud provider configurations against ISO 27799 controls using automated compliance scanning tools.

Module 5: Incident Response Planning for Healthcare Data Breaches

  • Defining breach thresholds based on data type, volume, and exposure context (e.g., lost device vs. ransomware).
  • Establishing a cross-functional incident response team with representation from legal, compliance, and clinical leadership.
  • Creating playbooks for common breach scenarios such as phishing attacks targeting billing staff or insider misuse.
  • Integrating SIEM alerts with EHR audit logs to accelerate detection of anomalous access patterns.
  • Preserving chain of custody for forensic evidence collected from clinical workstations and network devices.
  • Coordinating communication protocols to notify affected patients within regulatory timeframes (e.g., 60 days under HIPAA).
  • Conducting tabletop exercises with clinical and administrative staff to test response coordination under stress.
  • Documenting post-incident reviews to update controls and prevent recurrence of exploited vulnerabilities.

Module 6: Third-Party Risk Management in Clinical Ecosystems

  • Requiring business associate agreements (BAAs) that explicitly reference ISO 27799 control adherence for all vendors.
  • Assessing the security posture of medical device manufacturers during procurement and contract renewal.
  • Monitoring third-party access to internal systems through privileged access management (PAM) solutions.
  • Conducting on-site audits of cloud service providers hosting electronic health records.
  • Requiring evidence of penetration testing and vulnerability remediation from application service providers.
  • Enforcing data residency requirements for cross-border transfers involving patient data.
  • Implementing vendor offboarding procedures that include access revocation and data return or destruction.
  • Tracking third-party incidents through centralized logging and correlating them with internal risk exposure.

Module 7: Audit Logging and Monitoring in Clinical Systems

  • Configuring EHR systems to log all access to sensitive data elements such as HIV status or substance abuse records.
  • Ensuring audit logs capture user identity, timestamp, action type, and patient identifier for forensic reconstruction.
  • Protecting log integrity using write-once storage and cryptographic hashing to prevent tampering.
  • Establishing log retention periods that satisfy both ISO 27799 and jurisdictional legal requirements.
  • Integrating logs from disparate clinical systems (e.g., PACS, LIS, EHR) into a centralized SIEM platform.
  • Defining alert thresholds for anomalous behavior, such as after-hours access to large patient datasets.
  • Conducting regular log reviews as part of internal compliance audits and management oversight.
  • Testing log recovery procedures to ensure availability during breach investigations or regulatory inquiries.

Module 8: Privacy by Design in Health Information Systems

  • Embedding data minimization principles into EHR interface design to limit default data visibility.
  • Implementing dynamic consent management systems that reflect patient preferences in real time.
  • Conducting privacy impact assessments (PIAs) before deploying new clinical applications or data-sharing initiatives.
  • Designing de-identification workflows that balance research utility with re-identification risk.
  • Configuring default privacy settings in patient portals to require explicit opt-in for data sharing.
  • Validating anonymization techniques using re-identification risk modeling tools.
  • Integrating privacy controls into DevOps pipelines for health IT application development.
  • Requiring privacy design documentation from vendors during system acquisition and integration.

Module 9: Regulatory Compliance and Audit Readiness

  • Mapping ISO 27799 controls to specific clauses in HIPAA Security Rule and HITECH Act requirements.
  • Maintaining evidence artifacts such as policy versions, training records, and risk assessment reports.
  • Preparing for unannounced audits by maintaining real-time access to compliance documentation.
  • Responding to regulator inquiries with targeted evidence rather than broad data dumps.
  • Conducting internal audits using checklists aligned with ISO 27799 control objectives.
