Taming the Beast: Managing the Integrity of Open Automation Infrastructure
Historically, most automation systems have run on proprietary networks, which were well-bounded and therefore relatively easy to maintain. In contrast, modern automation systems are a hybrid of mission-specific control technologies and Windows' based open systems. Although an open architecture creates abundant possibilities of configurations, "taming the beast" is essential to constrain the system for both maintenance and security purposes. To better manage these freedoms, companies are now deploying Common Operating Environments (COEs), which are uniform configurations of hardware and software, to help maintain the reliability and security of these systems. This paper discusses what should be included in the specifications for COEs, the benefits and the best solution for facilitating their compliance.
