A number of western infrastructure agencies collaborated to produce guidance on foundational requirements for OT Cybersecurity, addressing the first step of maintaining a useful asset inventory.

Guidance include what information to collect, as well as pointers where and how to source this info.

Nothing new in terms of concept, but practical tips will help defenders to shorten this exercise.

The guide suggests to conduct a physical inspection and logical survey by gathering detailed digital and network-based information about system components.

Cybersplice can assist with the logic survey by providing rapid visibility of OT networks using our Splicecloud platform.

Cybersplice can also create a secure private sensor network via Splice-net, which is an encrypted overlay network that works on top of existing carrier infrastructure, offering secure, carrier-independent connectivity. Furthermore, Cybersplice provides an ICS Secure Access Edge that incorporates logical isolation, vulnerability shielding via an encrypted overlay network, passive node discovery, and secure remote access for operators and support partners.
