IEC 62443 OT cybersecurity services for pharmaceutical manufacturers. The engagement covers the zone-conduit modeling, the Security Level (SL) targets, the patch management, the FDA cybersecurity guidance alignment, and the operating routine.
The zone-conduit modeling defines the security zones, the conduits between the zones, and the security requirements for each zone and conduit.
The Security Level (SL) targets define the security capability required for each zone and conduit. Typical SL targets for pharmaceutical manufacturers are SL 2 to SL 3.
The patch management covers the patch identification, the patch assessment, the patch testing, the patch deployment, the patch verification, and the patch documentation.
The FDA cybersecurity guidance (2023) for medical devices and the 2024 guidance for pharma require cybersecurity to be considered in the system design, the validation, and the post-market surveillance.
Use this IEC 62443 OT Cybersecurity page as a planning checkpoint before vendor selection, architecture review, validation scoping or implementation sequencing. The strongest next step is to compare the guidance with your current SOPs, system inventory, batch records, data flows and QA review routines so the discussion starts from evidence instead of assumptions.
For IEC 62443 OT Cybersecurity, prepare the records, owners, risks and decision criteria linked to zone-conduit modeling, security level targets, patch management, fda cybersecurity guidance. Useful evidence includes current process maps, interface lists, audit trail expectations, exception workflows, data retention rules and the business reason for changing the current operating model.
IT cybersecurity focuses on the data, the applications, and the user devices. OT cybersecurity focuses on the operational technology: the control systems, the production equipment, and the safety systems.
A typical IEC 62443 assessment takes 4-8 weeks.
