Microsoft Sentinel Operations Baseline
Microsoft Sentinel baseline for data connectors, analytics rules, workbooks, and incident workflow.
Project profile
- Engagement: Microsoft Sentinel detection and operations baseline
- Focus: Data connectors, analytics, incidents, workbooks, retention, and ownership
- Output: Connector inventory, detection backlog, triage workflow, and operations notes
Detection with an owner
Security logs were available, but data volume and rule count did not guarantee useful detection. The baseline focused on signals that operators could understand, investigate, and connect to an accountable response path.
Data onboarding, analytics, incident handling, visualization, retention, and cost were reviewed as one operating system rather than separate portal settings.
Baseline coverage
- Workspace, connector, source, and data-quality inventory
- Analytics-rule purpose, severity, entity mapping, and tuning
- Incident triage, enrichment, escalation, and closure
- Workbooks and operational review views
- Retention, ingestion cost, health monitoring, and ownership
Decisions recorded
Detections were prioritized by threat relevance, data readiness, and response capability. Noisy or unowned rules remained in a tuning backlog, and automation required explicit scope, failure handling, and human review.
What to be aware of
- More data can increase cost without improving detection.
- A rule is not operational until ownership and response are defined.
- Connector health and source quality affect every dependent analytic.
- Tuning must continue as users, systems, and threats change.
Outcome
Security teams received a lean starting point for monitoring and response with clearer detection purpose and incident ownership. Coverage gaps and tuning work remained visible.
Evidence of delivery
- Connector and data-source inventory
- Analytics-rule decisions and tuning notes
- Incident workflow and escalation records
- Workbook and retention design
- Operations and improvement backlog
