Communication is key for the success of many endeavors, but when it comes to IT/OT convergence, it's even more important. To ensure good communication, both IT and OT need to use commonly understood terminology to reduce confusion, especially when it comes to the security of the critical infrastructure that control systems protect. Terms like "air gap" can mean one thing to an OT professional, but another to an IT professional.

He argues that industry needs to find an agreed-upon terms to communicate with IT and networking professionals and proposes "islanding" as an alternative.
