One of the big surprises from the 2021 SANS OT/ICS Survey was the widescale adoption of cloud technologies to support OT operations. According to the survey, 49% of respondents were using cloud technologies for operations support, and 32% were using cloud technologies for control critical activities. The survey also identified remote access as the No. 1 initial intrusion vector which would seem to be at odds with adding hosted services into critical control loops. Increased reliability and reduced total cost of ownership may be driving this trend, despite the connectivity requirements that come with it.
In this webcast, SANS survey author and ICS 515 certified instructor Mark Bristow was joined by Technology Evangelist Chris Grove, CISSP, NSA-IAM from Nozomi Networks to explore some of the business and operational drivers behind this result and provide an outlook into what’s next for ICS cloud applications.
