With increased connectivity at all levels, it is more important than ever that industrial automation suppliers secure not only networks or individual components but entire automation systems as well. After years of work toward this goal, Emerson has achieved the industry's first ISASecure System Security Assurance (SSA) Level 1 certification for its DeltaV distributed control system (DCS) and safety instrumented system (SIS) v.14.3. Emerson executives mentioned the certification a couple times during the Emerson Global Users Exchange in San Antonio last fall, noting how it set the company's DeltaV apart. "It's the first and only process control system to receive ISASecure SSA Level 1 certification, rather than look at individual components," said Peter Zornio, chief technology officer for Emerson Automation Solutions, at the time. Now Emerson has made a formal public announcement, sharing further details behind the certification.
