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.

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.
