Free Labshock Masterclass: Building Your First OT Detection
Real OT detection does not start with an alert. It starts by connecting PLC activity, industrial protocols, detection systems, SIEM platforms, analysts, and process impact into a single operational chain.
Most OT security programs stop at the IDS layer.
An alert is generated.
An event is logged.
The workflow ends.
Real OT detection starts when the entire chain is connected.
PLC → Protocol → IDS → SIEM → SOC Analyst → Physical Impact
Every layer contributes context.
Without that context, security teams see events.
Not consequences.
Why This Matters
Industrial systems are different from traditional IT environments.
A protocol message is not just network traffic.
It can change a physical process.
A single command may:
- Open a valve
- Start a pump
- Stop a motor
- Modify a setpoint
- Change a process state
The network event is only part of the story.
The physical consequence is what matters.
The Detection Chain
The upcoming Labshock Masterclass demonstrates how a complete OT detection workflow is built from the ground up.
The process follows a single event through multiple layers of the environment.
Step 1: Generate Industrial Activity
A Modbus write command is created.
The traffic is sent to a PLC.
Step 2: Observe Protocol Behavior
The industrial protocol transaction becomes visible on the network.
Communication can be analyzed and inspected.
Step 3: Trigger Detection
The IDS identifies the activity.
An event is generated.
Step 4: Forward Telemetry
Detection data is forwarded into Splunk.
The event becomes part of the broader security workflow.
Step 5: Generate Alerts
Correlation logic evaluates the activity.
Alerting rules are executed.
Step 6: Investigate
The SOC analyst receives the alert.
Investigation begins.
The analyst can now connect network activity to process behavior.
One Event. Multiple Layers.
A Modbus write operation looks simple on the network.
But the resulting process change may be significant.
A valve opens.
A tank level changes.
A pump starts.
A process state shifts.
The network may appear normal.
The process may already be changing.
This is where OT security differs from IT security.
The Missing Context
Many detection programs focus only on logs.
Many analysts only see alerts.
Many investigations stop at network evidence.
But industrial environments require another layer.
Process context.
Without process context, analysts see only part of the system.
They know what happened on the network.
They do not know what happened to the process.
What the Masterclass Covers
The Labshock Masterclass demonstrates how to build a complete OT detection workflow using realistic industrial traffic and operational environments.
Participants will follow a detection from:
- PLC activity
- Industrial protocol communication
- IDS detection
- SIEM ingestion
- Correlation logic
- Investigation workflow
- Process impact analysis
The objective is simple.
Move beyond alerts.
Understand the process.
Because OT security is not only about network visibility.
It is about understanding how cyber events affect physical systems.
If alerts are visible but process impact is not,
half of the system remains invisible.
OT security must be testable.
Not documented.
