It is an extension of why we still see most ICS deployed in a manner not following the ICS vendor’s own secure deployment guides, even in cases where the ICS vendor deploys the system.

It adds complexity to the project / service.

Asset owners are not requesting it, let alone insisting on it.

This isn’t happening in most cases for three reasons: We should be using the existing ICS deep packet inspection (DPI) technology to implement granular least privilege access from the cloud to the asset owner ICS. Most closed loop ICS cloud services do not require an all or nothing access decision. This risk should decrease over time if more asset owners start auditing the promised security controls. Shockingly failing audits that were pre-scheduled and performed in conjunction with the cloud service provider. In my audit experience to date, many are not.

The asset owner has to trust the ICS cloud service provider is following those nicely written security controls.

Get into the cloud service provider, in any way hack, bribe, extortion, nation state demand, physical attack, and the adversary now may have access to 1800 power plants or 680 factories or …

The cloud service provider is a big, juicy target that is even more attractive to an adversary as they sign up more customers.

Trust that the cloud service provider is actually implementing the VPN, patching, two-factor authentication, background checks, physical security, that is described in the security section of the offering. The closed loop ICS cloud service offerings I’ve seen through working with both cloud service providers and asset owners purchasing the cloud service have been based on trust. Most of the sectors and use cases will fall between these two extremes. And a small amount where the consequence of compromise is so low that simply putting in a VPN and trusting the cloud service provider will be sufficient. Sure there will likely be some sectors and use cases, such as nuclear, where this will not happen anytime soon.
