I want to discuss a subject that doesn’t get enough attention in the world of OT/ICS cyber security considering how fundamental it is, and also sparks a surprising amount of controversy. The topic is the importance of conducting ongoing research into OT endpoint device vulnerabilities, particularly for legacy devices.

It should be a unanimous opinion that this research is important. The more we know about vulnerabilities and the more CVEs we generate, the better for everyone involved. However, I frequently encounter industry analysts and self-styled experts that repeatedly question the need and validity of research in the OT sector. Their argument is that legacy equipment is guaranteed to have vulnerabilities, that it is flawed by design and therefore advanced endpoint research is unnecessary. I find this argument ironic because these same experts are often involved in creating products that help detect and manage the vulnerabilities found by researchers. They state publicly that there is no point in doing research and then in the same breath talk about how their product can help mitigate the problems.

Thanksgiving – when families get together and express gratitude for everything they have, accompanied by good food and hopefully great football. For most families and network security teams who just feel like family, this is a great time for looking back and evaluating the past year and giving thanks for how far we’ve come.
