The Role of Enterprise Architecture in DORA Compliance

The Digital Operational Resilience Act (DORA) introduces a paradigm shift in how financial institutions approach Enterprise Architecture (EA).

Historically, EA was focused primarily on aligning ICT systems with business objectives and optimizing operations.

With DORA, the focus has expanded to include operational resilience, real-time compliance, and secure system designs that can withstand disruptions.

Enterprise architects are now tasked with designing systems that meet regulatory demands while supporting continuous monitoring, automated auditing, and seamless third-party risk oversight.

The role of tools like LeanIX Enterprise Architecture becomes critical in enabling architects to:

• Visualize Dependencies: Map ICT systems and their relationships to identify vulnerabilities and critical dependencies.
• Automate Compliance Auditing: Track compliance metrics in real time and generate automated reports for regulatory authorities.
• Enhance Third-Party Oversight: Continuously monitor vendor performance, flag risks, and ensure third-party compliance with DORA standards.
• Streamline Incident Reporting: Use integrated workflows to automate regulatory reporting, meeting DORA's timelines efficiently.

By leveraging EA tools, enterprise architects can transition from static compliance strategies to dynamic, real-time governance systems that align with DORA's requirements.

1. Enhanced Focus on Security Architecture

Under DORA, financial institutions must design ICT systems that integrate robust security measures. EA enables architects to create secure, proactive architectures that can withstand and mitigate threats.

EA’s role in security:

• Visualize high-risk areas with EA tools and prioritize mitigation for critical systems.
• Embed security features such as multi-factor authentication, encryption, and firewall integration into systems at the design phase.
• Automate threat detection by integrating EA with security tools like SIEM systems, enabling real-time alerts and isolation of compromised components.

Practical steps:

1. Use an EA tool such as SAP LeanIX to map critical system dependencies, assess and quantify potential impact to support operational resilience testing.
2. Document DORA requirements, security frameworks, and compliance measures in a business process management tool such as SAP Signavio, while also modeling disaster recovery plans to support internal and external audits.
3. Integrate threat detection systems, enabling immediate responses to identified risks.

Example: A bank integrates SAP LeanIX to visualize the dependencies between its core banking system and external APIs, ensuring that encryption protocols were implemented in all vulnerable areas. At the same time, the bank uses SAP Signavio to document this framework and align it with GDPR and DORA compliance.

2. Governance and Compliance

DORA requires continuous compliance monitoring and efficient audit preparation. EA facilitates these processes by embedding governance tools and automating compliance workflows.

EA’s role in governance:

• Automate the collection of compliance metrics, generating real-time dashboards for internal and external reporting, while providing insights into the dependencies between processes, applications, and technology to strengthen digital resilience.
• Create audit trails that log all system changes, making them easily retrievable for regulatory reviews.
• Develop workflows that flag non-compliant systems and assign remediation tasks automatically.

Practical steps:

1. Configure SAP LeanIX dashboards to track compliance metrics and identify gaps.
2.  governance frameworks directly to business workflows in SAP Signavio Process Manager, ensuring transparency.
3. Use automated workflows to manage and document continuous audits.

Example: An insurer automates its compliance reporting using SAP LeanIX, reducing reporting cycles from weeks to hours while ensuring data accuracy.

3. Resilience by Design

Resilience is foundational to DORA, requiring ICT systems to withstand disruptions and recover swiftly. EA enables resilience by embedding redundancy, failover mechanisms, and disaster recovery strategies into systems.

EA's role in resilience:

• Design redundant architectures that ensure operational continuity even during outages.
• Simulate disaster recovery scenarios to validate and improve recovery plans.
• Automate the scheduling and execution of resilience testing, ensuring consistent compliance.

Practical steps:

1. Utilize SAP LeanIX simulations to assess recovery strategies for identified vulnerabilities.
2. Document disaster recovery timelines and protocols in SAP Signavio, linking them to broader workflows.
3. Implement redundant systems for mission-critical applications.

Example: A financial institution designs failover mechanisms through SAP LeanIX, automatically shifting operations to a backup data center during server outages.

4. Integration of Incident Response Mechanisms

DORA mandates real-time detection and reporting of ICT-related incidents. Enterprise architecture frameworks integrate monitoring tools and workflows to ensure rapid detection, response, and reporting.

EA’s role in incident response:

• Embed real-time monitoring systems into EA to detect incidents early and trigger alerts automatically.
• Standardize and automate incident escalation and resolution processes.
• Create reporting templates for regulatory submissions, ensuring compliance with DORA timelines.

Practical steps:

1. Set up SAP LeanIX to auto-generate response workflows and tasks upon detecting anomalies and perform business impact assessment (BIA) to quantify potential disruptions to business operations.
2. Use SAP Signavio Process Governance to document and track incident management timelines.
3. Regularly update incident response playbooks, linking them to automated workflows.

Example: A payment processor uses SAP LeanIX to automate incident reporting, ensuring breaches are communicated to regulators within DORA’s required timelines.

5. Third-Party Risk Management

Managing risks from third-party ICT providers is a key focus of DORA. EA tools provide the visibility and control necessary to oversee vendor compliance and performance.

EA’s role in vendor oversight:

• Continuously track vendor performance metrics, such as SLA adherence and incident history, while managing contracts to ensure terms align with DORA compliance requirements.
• Automate due diligence processes, ensuring third-party providers meet DORA standards.
• Provide a centralized view of all third-party dependencies, allowing architects to quickly assess their impact on the broader IT landscape, while also tracking the operational resilience of providers.

Practical steps:

1. Consolidate vendor assessments in SAP LeanIX, ensuring a single source of truth for compliance data.
2. Use SAP Signavio Process Manager to document third-party evaluations and create risk mitigation workflows.
3. Track ongoing performance of vendors and address SLA violations promptly.

Example: A bank uses SAP LeanIX to monitor its cloud service provider’s security performance, automatically triggering alerts for SLA violations.

6. Operational Resilience Testing

DORA requires regular testing to validate ICT systems’ ability to handle disruptions. EA frameworks ensure that these tests are conducted effectively and inform ongoing system improvements.

EA’s role in testing:

• Schedule regular Threat-Led Penetration Testing (TLPT) and resilience assessments.
• Analyze test results to identify system weaknesses and recommend improvements.
• Automate testing workflows, ensuring tests are conducted consistently and results are documented for audits.

Practical steps:

1. Use SAP LeanIX to map dependencies across critical IT systems and identify high-priority areas for testing.
