Threat Intelligence Hunt and OT Anomaly Monitoring
AI-assisted threat analysis workflow for identifying, triaging, and investigating emerging cyber threats in Splunk environments while improving visibility, anomaly detection, and secure monitoring in operational technology systems.
The Problem
“AI-assisted threat hunting and OT anomaly monitoring for Splunk and cyber-physical environments”
Organizations face these key challenges:
Manual threat triage is slow and inconsistent across customer environments
Splunk searches can be expensive and create platform load when hunts are broad or poorly scoped
Threat intelligence is fragmented across reports, feeds, and analyst notes
OT monitoring often lacks contextual anomaly detection across process, network, and asset data
Impact When Solved
The Shift
Human Does
- •Review threat reports, feeds, and analyst notes to identify relevant threats
- •Write, tune, and schedule Splunk searches for hunts and alert validation
- •Investigate alerts manually across logs, asset context, and customer environments
- •Monitor OT dashboards and static thresholds, then escalate anomalies case by case
Automation
Human Does
- •Approve hunt priorities, search execution, and detection changes for customer environments
- •Validate AI triage findings and decide investigation or escalation paths
- •Review OT anomaly recommendations and authorize any high-risk operational response
AI Handles
- •Continuously summarize threat intelligence and map indicators to available telemetry
- •Generate scoped hunt hypotheses, SPL drafts, triage checklists, and investigation summaries
- •Prioritize alerts and hunts with evidence-backed recommendations and search cost awareness
- •Detect multivariate OT anomalies and correlate process, network, and asset context for operator visibility
Operating Intelligence
How it works
AI surfaces what is hidden in the data.
Humans do the substantive investigation.
Closed cases sharpen future detection.
Who is in control at each step
Each column marks the operating owner for that step. AI-led actions sit above the divider, human decisions and feedback loops sit below it.

Human lead
Approval, override, feedback
AI scans and assembles evidence autonomously. Humans do the substantive investigation. Closed cases improve future scanning.
The Loop
6 steps
Scan
Scan broad data sources continuously.
Detect
Surface anomalies, links, or emerging signals.
Assemble Evidence
Pull related records into a working case file.
Investigate
Humans interpret evidence and make case judgments.
Authority gates · 1
The system must not execute hunts or searches in customer environments without analyst approval when operating in approved-search workflows [S1].
Why this step is human
Investigative judgment involves ambiguity, legal considerations, and stakeholder impact that require human expertise.
Act
Carry out the human-directed next step.
Feedback
Closed investigations improve future detection.
