Log Management Assessment & Rationalization Plan
Provincial Government, Ontario Ministry of Health
Overview
The Ontario Ministry of Health engaged Codeview Digital to assess and rationalize their log management practices across the province's healthcare systems. With over 200 provider-facing applications generating petabytes of unstructured log data across multiple platforms, the Ministry needed a clear strategy to reduce costs, mitigate compliance risks, and enable effective incident investigation.
The Challenge
The Ministry's log management had grown organically without governance or standardization, creating significant operational, financial, and compliance risks across the healthcare ecosystem:
- 14 petabytes of unstructured logs spread across 7 disconnected platforms with no unified access
- Critical PII exposure due to inconsistent log masking practices across healthcare applications
- $1.2M per year in wasted cloud storage costs from duplicate and redundant log retention
- Inability to perform cross-system incident investigations during critical patient data outages
- Non-compliance risks with PHIPA, PIPEDA, and Ministry security policies for health data handling
- No standardized log schema, making correlation across hospital networks and applications impossible
The Solution
Full-Scope Assessment
Performed a 4-week assessment spanning 200+ healthcare applications, including tool capability scoring across all 7 platforms, log duplication analysis, and governance gap identification.
Log Duplication Analysis
Identified 47% log duplication across platforms through systematic analysis of log sources, routing paths, and retention policies, uncovering $580K/year in potential storage savings.
Hybrid Architecture Strategy
Developed a hybrid centralized/decentralized log management strategy that balances cross-system visibility with the operational reality of distributed healthcare networks.
PII Handling Protocols
Designed a log standardization framework with thorough PII masking and handling protocols aligned with PHIPA, PIPEDA, and Ministry security policies for sensitive health data.
Standardized Log Schema
Established a unified log schema framework adopted across 15 hospital networks, enabling consistent log formats and cross-system correlation for incident investigations.
Transition Roadmap
Delivered a 12-month phased migration roadmap with detailed cost/benefit analysis, risk mitigation strategies, and milestone-based success criteria for the rationalization program.
