Remote access and technical support for OT environment
How is this solved and what to consider?

Many manufacturing companies rely on support and assistance from specialized vendors to maintain and update critical parts of equipment in the production environment – such as PLCs, HMI, SCADA applications, switches, etc.

This means that a “connection” must be made from a support technician with his own PC to the OT infrastructure. This article discusses security controls and aspects to consider in different scenarios.

The document contains references to aspects and controls that should be carried out in relation to various standards such as NIST SP800-53 and IEC62443 3-3.
