Abstract
Security for network communications is internally generated by an industrial control system (ICS). The ICS is assembled in a known-good environment prior to connecting to another network. While in the known-good environment, one or more components of the ICS auto-negotiate () with other components, assigning () security tokens. These certificates are used to internally secure communications between the components prior to any connection to other devices and without relying on external provisioning of the security tokens during commissioning () of the ICS.
