As digital health platforms become more complex, Identity and Access Management (IAM) has evolved into a crucial element of trust, governance, and functionality, rather than just a compliance requirement. In the ComfortAge project, a multi-stakeholder initiative funded by the EU to promote active and healthy aging, ROPARD0 is taking the lead in integrating IAM as a full technology partner.
By designing and implementing an advanced IAM solution, ROPARDO helps ComfortAge adhere to strict security standards while ensuring accessibility and scalability across various regions and services.
IAM in ComfortAge: Why Identity Matters in Elderly-Centric Digital Health
In ComfortAge, we’re engineering a platform that interconnects a wide spectrum of actors – elderly users, caregivers, healthcare institutions, application providers – over a distributed network. Each of these actors needs tailored access rights to securely interact with health data and services.
This creates challenges typical of next-gen healthcare platforms:
- Managing federated user identities across countries and institutions
- Enforcing role- and attribute-based access control (RBAC/ABAC)
- Supporting multi-factor authentication (MFA)
- Maintaining security continuity across centralized and edge deployments
At ROPARDO, we addressed these with a modular, policy-driven IAM strategy that ensures strong data protection while allowing flexible user experiences.
The IAM Architecture: Built to Scale, Built for Trust
Our security architecture for ComfortAge is based on Keycloak, a leading open-source IAM platform. We implemented both centralized and distributed IAM services, ensuring both resilience and compliance across multiple domains.
Key architectural domains:
- Core IAM Domain: Manages identities, roles, access policies, and authentication services.
- Application Domains: Individual services (e.g., digital diet coach, monitoring dashboards) mapped to domain-specific roles.
- Edge Domains: Deployed in local healthcare nodes, allowing offline operation while syncing securely with the central Keycloak instance.
This multi-domain architecture ensures interoperability while preserving data governance rules specific to regions or institutions.
Policy-Driven Identity Governance: Secure by Design
Behind every secure digital health platform lies a well-governed identity lifecycle. In ComfortAge, we designed the identity governance layer to be both structured and adaptable, recognizing that elderly care environments involve dynamic roles, temporary users, and varying data access needs.
At ROPARDO, we implemented a policy-driven framework where user and service identities are not just created; they are carefully orchestrated. Onboarding any identity, whether a healthcare professional, caregiver, or a connected IoT device, follows a formally approved request chain, verified by domain-specific administrators. This gives organizations full control over who accesses what and when.
We adopted a zero-local-account policy across all user-facing applications. This means no ad-hoc or unmanaged logins; everything flows through the centralized IAM layer to ensure traceability and uniform policy enforcement. Access roles are strictly bound to functional responsibilities, not individuals, and are always granted under the principle of least privilege.
When elevated permissions are needed – for example, during system upgrades or audits – our “just-in-time access” model activates temporary roles that expire automatically. No more forgotten superuser accounts lingering in the background.
This controlled flexibility ensures a secure, auditable, and user-friendly experience while also meeting the rigorous compliance standards of EU healthcare governance.
Consent and Data Sovereignty: Built-in, Not Bolted On
Trust in digital health extends beyond secure access; it requires clear, traceable user consent for every interaction involving personal or medical data. In ComfortAge, consent is not implied. It is explicitly captured, versioned, and revocable at any point in the user’s journey.
Our IAM integrates consent management as a first-class citizen. Elderly users (or their legal representatives) are presented with readable, localized consent forms before their accounts are activated. These include information about what data will be collected, who will access it, and for what purpose.
Each consent decision, be it acceptance, withdrawal, or update, is logged and timestamped, providing an audit trail to prove compliance with GDPR and other healthcare regulations. If a user decides to withdraw consent for a certain service (e.g., activity monitoring), the IAM system automatically revokes access rights and alerts relevant services.
By embedding consent directly into our identity lifecycle, we support not only legal compliance but also ethical digital design, where users have control over their information and feel respected within the digital environment.
Federated Identity & MFA: Access Without Compromise
Given ComfortAge’s pan-European footprint, federated login is critical. Our IAM supports both SAML 2.0 and OpenID Connect protocols, enabling users to authenticate using institutional credentials or trusted third-party identity providers.
For privileged accounts and sensitive roles (especially healthcare professionals), multi-factor authentication (MFA) is mandatory. We support:
- TOTP (Time-based One-Time Passwords)
- 509 certificates, issued through ComfortAge’s internal Public Key Infrastructure (PKI)
This dual-layered approach significantly reduces the risks of unauthorized access, even in the event of credential theft.
Auditability & Real-Time Security Insights
Visibility is power, especially when operating a healthcare platform that spans multiple institutions and national jurisdictions. At ROPARDO, we engineered auditability into the very fabric of ComfortAge’s IAM layer.
Every critical action – successful or failed logins, password resets, role changes, consent withdrawals – is logged with full metadata: timestamps, user identifiers, client device, and origin IP. This gives security teams a complete timeline of events, supporting both proactive monitoring and forensic investigations.
But we don’t stop at logs. We’re actively building out an ecosystem of automated alerting and anomaly detection tools. This enables the system to flag suspicious behaviors, like multiple failed login attempts across regions or unexpected privilege escalations, in near real-time. These alerts feed into a central monitoring dashboard and are actionable by system operators and security officers.
In a sector where any unauthorized access can have life-threatening consequences, this level of observability is not optional, it is fundamental.
IAM Maturity Model: Scaling Security with the Platform
Security isn’t a one-time implementation, it’s a lifecycle. From the start, ROPARDO approached IAM in ComfortAge with a clear maturity model that enables the platform to evolve without compromising trust or performance.
We structured the roadmap into three progressive stages:
- Level 1: Basic Governance – IAM policies are defined, but processes may still rely on manual interventions.
- Level 2: Policy Enforcement – Policies are codified, and processes are repeatable, with limited automation.
- Level 3: Full Automation – IAM integrates directly into the DevOps pipeline, enabling real-time provisioning, automated auditing, and self-healing access controls.
At present, ComfortAge operates solidly at Level 2, with standardized onboarding and de-provisioning workflows, federated identity integration, and secure edge authentication. ROPARDO is actively leading the evolution to Level 3 by:
- Integrating IAM with CI/CD for service registration and access updates
- Automating onboarding flows via API
- Implementing real-time log streaming to analysis engines
- Expanding user self-service features for consent and MFA management
This maturity approach ensures that as ComfortAge scales to serve more users, devices, and services, its trust framework scales with it, seamlessly and securely.
Engineering Trust for Digital Aging
Digital platforms that support aging populations must be trustworthy by default. ComfortAge is not just a set of tools, it’s an integrated digital ecosystem where security and usability coexist.
At ROPARDO, we don’t treat IAM as an afterthought or technical burden. For us, Identity and Access Management is a user-enabling, risk-reducing, compliance-driven engine at the heart of digital transformation in healthcare.
By aligning IAM with usability, governance, and resilience, we help ensure that every ComfortAge user, be it an 80-year-old retiree or a hospital IT admin, interacts confidently with our systems.
