DORA Compliance Logging & Resilience Blueprint

Client Challenge

With the enforcement of the European Digital Operational Resilience Act (DORA), the client needed to prove operational resilience across their core trading platform. Their existing telemetry was siloed across separate cloud providers (AWS trading engines, Azure Active Directory, and SaaS CRM vendors).

Key regulatory bottlenecks included lacking immutable log storage, undefined third-party ICT service provider dependency mapping, and inability to produce the 24-hour initial incident notification mandated by DORA Article 19.

Strategy & Architectural Blueprint

M.Sher designed a centralized DORA resilience framework focused on three technical controls:

• Immutable Logging Pipeline: Configured Write-Once-Read-Many (WORM) S3 Object Lock and Azure Immutable Blob storage with automated lifecycle policies, guaranteeing 5-year tamper-proof log retention at 70% lower cost than hot SIEM storage.
• DORA Articles 9 & 10 Control Mapping: Built unified monitoring dashboards aggregating ICT availability metrics, API response latencies, and authorization anomalies across all critical service providers.
• Automated Incident Playbooks: Developed automated triage runbooks within Chronicle SOAR to classify, correlate, and produce standardized DORA incident reporting templates within 2 hours of major anomaly detection.
• Third-Party ICT Risk Framework: Formulated vendor audit assessments and automated security posture gates for third-party SaaS integrations.

Measurable Business Impact

• Full Regulatory Sign-Off: Achieved zero findings during the formal European Central Bank (ECB) supervisory review.
• 400+ Engineering Hours Saved: Automated compliance evidence collection eliminated manual screenshot gathering during quarterly audits.
• Cold Tiering Cost Savings: Moving non-critical telemetry to immutable cold storage saved £65,000 annually compared to keeping all logs active in analytics clusters.
