These points aim to provide practical and relevant information for users implementing FrameworX in a security-conscious environment.

• Introduction to IEC 62443

  • Brief overview of the IEC 62443 series of standards and its importance for securing Industrial Automation and Control Systems (IACS).

  • Explanation of the core concepts, such as Security Levels (SL), Zones, and Conduits.

• FrameworX Architecture and IEC 62443 Alignment

  • Discussion on how FrameworX’s architecture and features inherently support the implementation of a secure environment according to IEC 62443 principles.

  • Mapping of FrameworX components to a typical Zones and Conduits model.

• Implementing Foundational Requirements (FRs) with FrameworX

  • Practical guidance on how to use FrameworX features to meet the seven Foundational Requirements of the standard:

    • Identification and Authentication Control (IAC): Configuring users, groups, and security policies.

    • Use Control (UC): Setting up access permissions and privileges for different roles.

    • System Integrity (SI): Utilizing features like encrypted communication and system diagnostics.

    • Data Confidentiality (DC): Implementing secure data transmission with HTTPS, SSL, and VPNs.

    • Restricted Data Flow (RDF): Configuring firewalls and managing data flow between security zones.

    • Timely Response to Events (TRE): Using the logging, auditing, and alarm features to monitor security events.

    • Resource Availability (RA): Implementing redundancy and failover configurations.

• Secure Deployment Guide

  • A checklist or best-practices guide for deploying a FrameworX solution in a way that aligns with IEC 62443.

  • Example reference architectures for common deployment patterns.

• Further Resources

  • Links to official IEC 62443 documentation and relevant industry white papers.

Review to do:

What is IEC 62443 (scope & who should read)

• Series overview (1-1 terms; 2-1/2-4 org/process; 3-2 risk/zone-conduit; 3-3 system SR/SL; 4-1/4-2 product & component).

• Target roles: architects, integrators, IT/OT security, operations leads.

Core concepts

• Zones & conduits; defense-in-depth; Security Levels (SL-T 1–4).

• Foundational Requirements (FR1–FR7): Identification & Authentication, Use Control, System Integrity, Data Confidentiality, Restricted Data Flow, Timely Response to Events, Resource Availability.

Mapping to FrameworX features (control-by-control)

• Identification & Authentication / Use Control: Security module (users, roles, policies), AD/LDAP integration. 

• Restricted Data Flow / Data Confidentiality: HTTPS/SSL, Secure Multi-Port Gateway, segmented client access.   

• Timely Response / Auditability: Alarms & notifications; Audit Trail usage. 

• Resource Availability: Redundancy configuration; Runtime/System Monitor; failover checks. 

Architecture patterns aligned to IEC 62443

• Purdue L1–L4 zoneing notes; place servers/clients; DMZ/edge patterns. 

• Examples: Standalone, Distributed, Cloud/Hybrid, Hot-Standby. 

Implementation checklist (link out to How-to pages)

• Asset inventory → risk & SL-T per zone → zone & conduit diagram.

• Configure authN/authZ (roles/permissions, AD/LDAP). 

• Harden comms & endpoints (HTTPS/SSL, multi-port gateway; close unused ports).   

• Logging & audit (Audit Trail) and time sync. 

• Availability: redundancy, backup/restore, drills; document evidence. 

• SBOM & hardening references. 

Evidence & testing

• Map tests to FR/SL controls; link to Diagnostics/Performance tools for verification.

Optional sibling (if you want a short concept too)

• IEC 62443 for FrameworX Architects (Concepts) — a 1-page primer that points to the Reference above and to the How-to Guides (zone & conduit, hardening, redundancy). This keeps the taxonomy pure while giving newcomers an easy entry point.
