OT / ICS / SCADA Security

Passive OT security assessment analyzes industrial control traffic captures to identify unsafe exposure and segmentation gaps while preserving process continuity. This approach avoids active scanning to prevent safety or availability incidents in operational technology networks.

The Purdue model maps ICS environments into enterprise, IDMZ, operations, supervisory, control, and process layers. Reviewing these layers helps identify boundary violations and missing conduits to enforce proper segmentation between corporate and industrial networks.

Passive protocol analysis detects risky Modbus write operations by summarizing captured SCADA traffic and flagging high-risk industrial actions. This method identifies unsafe talkers and control-relevant behavior without injecting packets into the live network.

Yes, OT security posture assessments map identified boundary violations and exposure risks directly to MITRE ATT&CK for ICS. This alignment provides standardized threat context and helps prioritize remediation advice for industrial control system vulnerabilities.

You can generate read-only external exposure checks to safely identify unsafe industrial protocol exposure. These passive checks ensure no write operations or disruptive commands are sent to operational technology assets during the security review.

IEC 62443 and NIST SP 800-82 guide ICS remediation by providing structured frameworks for boundary protection and risk mitigation. Mapping OT findings to these standards ensures industrial security controls align with recognized industry best practices.
