RMC Announces Sponsorship of the SANS Institute’s 2023 ICS/OT Cybersecurity Survey

ARLINGTON, Va., April 24, 2023 – RMC, the leader in Risk Management, Industrial Cybersecurity, and Mission Assurance services is a proud sponsor of the SANS Institute’s 2023 ICS/OT Cybersecurity Survey. As a leading provider of ICS/OT cybersecurity services, we recognize the importance of understanding the evolving threat landscape to provide the best possible services to our commercial and federal clients.

The survey is now open for responses and we encourage all ICS/OT security practitioners to provide your valuable input. Your participation is critical to help the community better understand the ever-changing ICS threat landscape and explore how critical infrastructure defenders across all sectors are constantly adapting to address new challenges and threats.

The SANS Institute has a long-standing reputation for excellence in cybersecurity research and education, and their annual survey provides valuable insights into the state of ICS/OT cybersecurity. The results of the survey will help organizations, governments, and security providers understand the current risks facing critical infrastructure and make informed decisions about how to mitigate them.

As a sponsor of this important initiative, RMC is committed to promoting awareness of the survey and encouraging participation from all corners of the industry. By working together, we can help to Assure Tomorrow for critical infrastructure and the communities it serves.

Best regards,

Vince Kuchar

CEO, RMC Global

What’s the Difference Between OT, ICS, SCADA and DCS?

Every day, multiple technologies work in the background to make modern life possible. Two of the most important examples include Information Technology (IT) and Operational Technology (OT). While most of us recognize IT as a term that broadly encompasses digital computing, what about OT?

OT can be difficult to understand, but that’s only because most of us are unaware of the nomenclature. In recent times, exciting developments are bringing about a convergence between OT and IT that have big implications for technology and industry.

In this article, we’ll define what it is, and how it relates to other terms.

Operational Technology

Industrial Control Systems

OT or Operational Technology encompasses the computing systems that manage industrial operations. This includes monitoring of Oil & Gas, the Electric Utility Grid, manufacturing operations, and more.

Simply put, OT runs the networks that allow common civilized norms to continue like the electricity turning on in your house or the clean running water coming out of your faucet.

Industrial Control System

Industrial Control System (ICS) is an umbrella term that includes both SCADA and DCS. An ICS network can monitor many infrastructure and raw material systems. For instance,

  • Conveyor belts in a mining operation
  • Power consumption in the electric grid
  • Valve pressures in a natural gas facility

ICS networks are mission critical, requiring immediate and high-availability. In many ways, this emphasis represents the main difference between IT and OT/ICS systems. For IT, security is high priority preserved by the Confidentiality, Integrity, and Availability (CIA) triad. In OT/ICS networks, both integrity and confidentiality come second to availability.


Supervisory Control and Data Acquisition (SCADA) is a systems architecture for managing large and complex processes. SCADA systems are normally found in utility providers such as natural gas and electric power transmission, where control functions are distributed over a large geographic area.

SCADA systems consist of three main components:

  1. central command center consists of all the servers running SCADA software
  2. Multiple, remotely located local control systems directly control and automate process equipment
  3. Communication systems connect the servers at the central command center to the remote locations

The main purpose of SCADA is data acquisition: the networks consist of multiple remote terminal units (RTUs) that are used to collect data back at the central command center, where they can be used to make high level decisions.

Distributed Control System

Distributed Control System (DCS) is a type of process control system that connects controllers, sensors, operator terminals and actuators. The data acquisition and control functions are performed by distributed processors situated near the peripheral devices or instruments from which data is being gathered.

While DCS and SCADA are functionally very similar, DCS is generally employed at large, continuous processing facilities. Operations are almost always controlled onsite rather than remotely.
