Busting ICS Cybersecurity Myth #1

Files/Data Movement in Air-Gapped Networks

  1. Review whether your ICS network is 100% air-gapped (absolutely no connection to/from the OT/ICS network to the outside, not even through a firewall or USB file transfers). Or is it only considered air-gapped because there is a firewall between ICS network and other networks?
  2. Review whether threat modelling/risk assessment has identified all threats and risks to your ICS network.
