Identity And Access Management in ISO 27799

This curriculum spans the design and operationalization of IAM systems in healthcare settings with a level of detail comparable to a multi-workshop program for implementing ISO 27799-aligned access governance across clinical, administrative, and federated environments.

Module 1: Aligning IAM with ISO 27799 Control Objectives

• Determine which ISO 27799 controls directly require IAM enforcement, such as access to patient health records under confidentiality requirements.
• Map IAM capabilities to specific clauses in ISO 27799, including access control (A.9), asset management (A.8), and human resources security (A.7).
• Establish ownership of IAM controls between information security, IT operations, and clinical data governance teams.
• Define thresholds for access review frequency based on risk profiles of data types (e.g., psychiatric records vs. administrative data).
• Integrate IAM audit trails with existing compliance reporting systems to satisfy ISO 27799 documentation requirements.
• Adjust role definitions in IAM systems to reflect healthcare-specific job functions such as attending physician, billing coder, or lab technician.
• Implement exception handling procedures for temporary access escalations during medical emergencies while maintaining auditability.
• Coordinate IAM policy updates with periodic ISO 27799 control assessments and internal audits.

Module 2: Healthcare-Specific Identity Lifecycle Management

• Design automated provisioning workflows that account for credentialing and privileging processes unique to healthcare providers.
• Integrate HRIS, credentialing databases, and EHR systems to trigger identity creation, modification, and deactivation events.
• Enforce time-bound access for locum tenens physicians and temporary staff based on contract end dates.
• Manage identity attributes such as NPI numbers, licensure status, and departmental affiliations within the identity store.
• Implement reconciliation processes to detect and remediate orphaned accounts after staff separation or role change.
• Support identity federation for affiliated clinics and external specialists while maintaining accountability.
• Define escalation paths for identity data discrepancies between payroll, clinical privileges, and access rights.
• Apply data retention policies to identity logs in compliance with healthcare privacy regulations.

Module 3: Role Engineering for Clinical and Administrative Access

• Conduct role mining using access logs from EHR, pharmacy, and radiology systems to identify actual usage patterns.
• Define role hierarchies that reflect clinical reporting structures, such as attending-resident relationships.
• Implement segregation of duties rules to prevent conflicts, such as a user billing and authorizing their own services.
• Limit role membership based on licensure scope (e.g., RNs vs. MDs) to enforce least privilege.
• Establish change control for role modifications, requiring clinical and security stakeholder approval.
• Address role explosion by creating dynamic roles based on patient assignment or care team membership.
• Integrate role definitions with clinical workflow systems to enable context-aware access decisions.
• Regularly review role entitlements against current clinical practice guidelines and system updates.

Module 4: Access Request and Approval Workflows

• Design multi-tiered approval chains for access requests, incorporating clinical supervisors and data stewards.
• Implement just-in-time access for high-risk systems with mandatory justification and time limits.
• Integrate access request forms with EHR user onboarding to reduce manual data entry and errors.
• Define escalation procedures for urgent access during clinical emergencies with post-facto review requirements.
• Enforce separation between requesters and approvers in administrative and financial systems.
• Enable delegated approval for department heads while maintaining audit trails of delegation authority.
• Log and retain access request metadata, including business justification and approver rationale.
• Automate revocation of temporary access upon expiration or early termination of assignment.

Module 5: Privileged Access Management in Clinical Environments

• Identify privileged accounts in EHR, backup systems, and medical device management consoles.
• Implement session monitoring and recording for database administrators with access to patient data.
• Enforce dual control for critical operations such as database schema changes or bulk data exports.
• Restrict privileged access to maintenance windows with pre-approval and justification logging.
• Isolate break-glass accounts used during system outages with immediate post-use review requirements.
• Integrate PAM solutions with SIEM to detect anomalous privileged behavior, such as off-hours access.
• Define recovery procedures for lost privileged credentials without compromising audit integrity.
• Conduct quarterly reviews of privileged account usage and entitlements across clinical IT systems.

Module 6: Audit and Access Review Execution

• Schedule automated access reviews based on user risk tier, with high-risk roles reviewed quarterly.
• Assign review responsibility to data owners, such as department heads or chief medical officers.
• Generate access certification reports that highlight deviations from role-based entitlements.
• Integrate attestation workflows with identity governance platforms to track response rates and escalations.
• Flag dormant accounts with access to sensitive data for immediate revocation or revalidation.
• Correlate access review findings with incident reports to identify potential control failures.
• Archive attestation records in tamper-evident storage to support regulatory audits.
• Adjust review scope dynamically based on system changes, such as EHR upgrades or new module deployment.

Module 7: Identity Federation and Interoperability Governance

• Define identity assurance levels for federated partners based on their authentication practices and risk exposure.
• Negotiate attribute release policies with external clinics to minimize data sharing while enabling access.
• Implement SAML or OIDC integrations with regional health information exchanges (HIEs) under trust agreements.
• Monitor token lifetime and refresh behavior to prevent unauthorized persistent access.
• Establish breach notification protocols for identity providers in federated arrangements.
• Enforce consistent MFA requirements across direct and federated access paths.
• Log and audit cross-organization access events for compliance and forensic investigations.
• Conduct annual assessments of federation partners' IAM controls as part of vendor risk management.

Module 8: Break-Glass and Emergency Access Protocols

• Define clinical scenarios that justify break-glass access, such as cardiac arrest or unconscious patients.
• Implement real-time alerts to supervisors when break-glass access is invoked.
• Log all actions performed during a break-glass session for post-event review and justification.
• Require users to provide a clinical reason before activating emergency access.
• Limit break-glass access duration to the minimum necessary for patient care.
• Integrate break-glass events with incident management systems for trending and root cause analysis.
• Conduct monthly reviews of all break-glass usage to detect misuse or process gaps.
• Train clinical staff on appropriate use and accountability associated with emergency access.

Module 9: IAM Metrics, Monitoring, and Continuous Improvement

• Track time-to-provision and time-to-deprovision for new hires and terminated staff against SLAs.
• Measure access review completion rates by department and escalate laggards to management.
• Monitor failed login patterns to detect potential credential compromise or system misuse.
• Calculate orphaned account rates across critical systems and assign remediation owners.
• Report on over-privileged users and progress in remediation efforts quarterly.
• Integrate IAM KPIs into executive risk dashboards for board-level oversight.
• Conduct root cause analysis on access-related incidents to drive control enhancements.
• Align IAM maturity assessments with ISO 27799 periodic review cycles.

Module 10: Integrating IAM with Broader Healthcare Security Controls

• Synchronize IAM policies with data classification schemes to enforce access based on sensitivity.
• Coordinate with DLP systems to block unauthorized access or exfiltration attempts by privileged users.
• Integrate user context from IAM into SIEM correlation rules for behavioral anomaly detection.
• Enforce MFA for all remote access to clinical systems, including telehealth and mobile devices.
• Link user deprovisioning to device wipe commands for BYOD and corporate-issued mobile endpoints.
• Validate that encryption key access is governed through the same IAM lifecycle processes.
• Ensure IAM controls are included in third-party risk assessments for cloud EHR providers.
• Participate in change advisory boards to assess IAM impact of new clinical system deployments.
