IOGP Report 627 – Selection of system and security architectures for remote control, engineering, maintenance, and monitoring


IOGP Members can also access all publications via the library in the Members Area


This document provides common definitions and guidelines on system architectures and security controls for remote functions such as remote operation, remote monitoring, remote engineering, and remote maintenance of Industrial Control and Automation Systems (IACS), Basic Process Control Systems (BPCS), Safety Instrumented Systems (SIS), package control systems, and monitoring-only systems. The objective of the document is to highlight specific risks and challenges related to remote function, provide a high-level  view of system and security architectural considerations, and present reference system architectures used to implement remote function for typical use cases.
