Detection

OT Security Monitoring and Detection Engineering

Use network, identity, remote-access, engineering, and endpoint evidence to detect activity that matters to physical operations.

Prioritize observable risk

Start with remote access, new communications, unauthorized engineering activity, controller changes, account misuse, boundary violations, and loss of expected telemetry.

Use appropriate data

Combine passive industrial network visibility with firewall, VPN, jump-host, Windows, identity, engineering-tool, and change-management records.

Define triage context

Include asset role, process function, maintenance state, expected operator, vendor involvement, approved change, and escalation contacts.

Validate detections safely

Use recorded traffic, simulations, lab environments, configuration review, and controlled administrative events instead of unsafe production exploitation.
