This policy defines the mandatory rules for securely deploying, managing, and monitoring all Internet of Things (IoT) and Operational Technology (OT) devices, from smart sensors and cameras to industrial control systems.
-
Secure Device Deployment
Ensure all IoT/OT systems are securely configured before deployment, with default passwords changed and all access approved.
-
Isolate Critical Networks
Enforce strict network segmentation by requiring all IoT/OT devices to be placed on a separate Wi-Fi or VLAN, isolated from core IT systems.
-
Enforce Vendor Accountability
Mandate that third-party vendors and installers follow secure practices and are contractually liable for the security of the devices they manage.
-
Maintain Compliance
Demonstrate alignment with key regulations like ISO 27001:2022, NIS2, and DORA for securing connected operational technologies.
Read Full Overview
The IoT-OT Security Policy for SMEs is an integral framework designed to secure Internet of Things (IoT) and Operational Technology (OT) devices within small to medium enterprises. As these devices increasingly interface with critical business operations, they become potential targets for cyber threats. This policy addresses the need for robust security measures to prevent unauthorized access, data breaches, and operational disruptions. Designed with SMEs in mind, this policy outlines clear and enforceable controls applicable to various environments, including office spaces, warehouses, and production floors. It applies to all individuals involved in the lifecycle of IoT and OT systems, from planning and installation to support and disposal. Key stakeholders such as employees, contractors, and external vendors must adhere to secure installation practices, ensuring that devices like smart locks, surveillance systems, and industrial controllers are configured and maintained securely. The policy enforces comprehensive monitoring and threat detection strategies, using tools like anomaly detection systems and firewalls to filter and log traffic between network zones. It mandates that all IoT/OT devices operate within logically segmented networks, isolated from internet-facing channels unless explicitly risk-assessed and encrypted. Furthermore, the policy emphasizes vendor accountability, requiring third-party providers to follow secure practices and submit to audits. It also outlines the responsibilities of General Managers in maintaining device inventories, overseeing security configurations, and ensuring compliance with regulatory standards such as ISO 27001:2022, GDPR, and NIS2. By implementing this policy, SMEs can confidently protect their operational environments, ensuring business continuity and compliance with international security standards. It provides a structured approach to managing IoT and OT security, offering peace of mind and clarity in a complex digital landscape.
