TL;DR: Arcon says Saudi Arabia’s OTCC requires critical infrastructure operators to move beyond ECC baselines and add OT-specific controls such as secure remote access, privileged session monitoring, immutable audit trails and vendor access governance. The real test is whether privileged OT operations can be governed with enough visibility and accountability without weakening resilience.
Editorial analysis by NHI Mgmt Group, based on content published by Arcon: “Operational Technology Cybersecurity Controls (OTCC)”.
Key questions
Q: How should security teams govern remote privileged access in OT environments?
A: They should treat OT remote access as privileged access governance, not simple connectivity.
A: Without session monitoring and audit trails, organisations lose visibility into who did what, when they did it, and whether access stayed within approved boundaries.
Q: What is the biggest governance gap in third-party OT access?
A: Vendor access often grows faster than the control process that governs it.
Practitioner guidance
- Implement OT-specific remote access controls Separate remote administrative paths for OT from general enterprise remote access, and require stronger authentication, approval, and network restriction for each privileged entry point.
- Enable privileged session monitoring Record and review elevated OT sessions so operators can reconstruct commands, changes, and support activity after the fact.
- Make audit trails tamper-resistant Store privileged access logs so they cannot be altered by the same operators whose activity they record, and retain them for compliance evidence.
Bottom line: OTCC extends Saudi Arabia’s baseline controls by requiring OT-specific governance over privileged access, remote support, session monitoring, and auditability.

OT privileged access is now a regulatory control plane, not a convenience layer: OTCC turns privileged operations into a compliance and resilience issue rather than a purely administrative one. In critical infrastructure, the question is no longer whether admins can reach the system, but whether every elevated action is justified, monitored, and reconstructable. Practitioners should treat OT PAM as part of operational governance, not a bolt-on security tool.
A few things that frame the scale:
- 97% of NHIs carry excessive privileges, increasing unauthorised access and broadening the attack surface, according to the Ultimate Guide to NHIs.
- 49% of IT professionals would prioritise improving privileged access management if the decision were theirs alone, according to Netwrix's 2023 Hybrid Security Trends Report.
A question worth separating out:
Q: How do OT privileged controls differ from standard IT PAM?
A: OT privileged controls must account for operational resilience, remote support, and physical process impact. That means tighter segmentation, stronger session visibility, and audit evidence that can stand up in regulated critical infrastructure environments. The difference is less about technology branding and more about the consequences of misuse.
