Access to operational technology (OT) systems is too broad
Many enterprises have fallen victim to security breaches due to attackers exploiting vulnerabilities of traditional VPNs and other appliance-based security solutions used to provide remote access to operational technology (OT) systems or Industrial Control Systems (ICS).
Vendors only need to access their specific ICS systems, so why introduce them to the OT network?
We know it’s risky to extend full and lateral OT network access to all users, but you need to provide them with access to their specific OT systems. The solution is to decouple OT systems management software access from the network, while segmenting access based on individual users and apps.

Remotely manage OT systems
Regardless of whether your organization will continue to offer remote work or trickle back to staffing a physical office, two questions to remotely manage OT systems remain:
Security as an element of OT cyber security programs
Security is ignored for the moment because it is assumed the organization already decided that remote access is a business enabler and therefore, it will look to add this capability to its portfolio.
Decrease risk exposure in OT environments
That example has a lot of potential risks, some of which can expose other risks for exploitation. To answer the second question above, here is a good guideline into looking at those risks at a minimum:
