OT Security FAQs

Question 1

What is OT Security and how does it help?

Accepted Answer

OT Security is a tool that provides queryable access to a comprehensive stack of Operational Technology (OT) security frameworks. It makes complex standards like IEC 62443, NIST 800-82, NIST 800-53, and MITRE ATT&CK for ICS searchable and AI-readable, helping control systems engineers, security architects, and compliance officers quickly find relevant information, cross-reference controls, and design secure systems.

Question 2

Which specific OT security standards does OT Security cover?

Accepted Answer

OT Security covers IEC 62443-3-3, IEC 62443-4-2, IEC 62443-3-2, NIST SP 800-53 Rev 5, NIST SP 800-82 Rev 3, and MITRE ATT&CK for ICS, offering a unified interface for all these critical industrial cybersecurity frameworks.

Question 3

How does OT Security assist with network segmentation and threat intelligence?

Accepted Answer

The tool provides guidance for network segmentation and zone/conduit architectures using the Purdue Model based on IEC 62443-3-2. For threat intelligence, it offers queryable access to MITRE ATT&CK for ICS techniques and mitigations, helping users understand and defend against common industrial control system threats.

Question 4

Can I integrate OT Security with AI clients?

Accepted Answer

Yes, OT Security is designed for the AI age. It functions as an MCP (Meta-Controller Protocol) server, allowing direct querying from AI clients like Claude Desktop and Cursor, enabling natural language interactions to retrieve security requirements and guidance.

Question 5

Does OT Security include the full content of IEC 62443 standards?

Accepted Answer

No, due to licensing restrictions, OT Security does not include the copyrighted content of IEC 62443 standards directly. It provides the database schema, ingestion tools, and JSON templates, but users must supply their own licensed copies of IEC 62443 standards and ingest them into the system.
