frequently asked questions
What is operational technology and how is it different from IT?
Operational technology (OT) refers to hardware and software that monitors and controls physical processes, such as turbines, pumps, valves, breakers and industrial control systems. The key difference from IT is that OT directly interacts with the physical world, so a security incident can affect physical safety, equipment and industrial processes in addition to data and services. OT environments also tend to place a higher priority on safety, availability and reliability than traditional IT environments, where confidentiality may receive greater emphasis. Many OT systems also have long lifecycles and may run on equipment that cannot be easily patched, rebooted or replaced without disrupting operations.
Why can’t critical infrastructure systems just be patched and updated?
Critical infrastructure systems can’t always be patched and updated as easily as traditional IT systems because of the disruption to physical operations. Many industrial control systems are designed to operate continuously, and taking them offline may require a scheduled outage that occurs only periodically. Organizations may also need to test and validate patches before deploying them, particularly when equipment is safety-critical or provided by a specialized vendor. Older systems may no longer receive security updates at all. As a result, OT security teams may rely on compensating controls such as network segmentation, continuous monitoring, application allowlisting and access restrictions when directly patching a system isn’t practical.
What is the Purdue Model?
The Purdue Model is a layered framework used to describe and segment industrial control system environments. It organizes systems according to their functions, from physical processes and field devices at the lowest levels to control systems, supervisory systems, site operations and enterprise IT at higher levels. Security teams can use the model to identify network boundaries, control communication between levels and determine where security monitoring and other controls should be placed. Modern OT environments don’t always fit neatly into the traditional Purdue hierarchy, particularly as industrial systems become more connected to enterprise and cloud environments, but the model remains a useful framework for discussing OT network architecture.
What regulations apply to critical infrastructure cybersecurity?
Critical infrastructure cybersecurity regulations vary substantially by sector, because different industries are subject to their own laws, regulations and standards. For example, electric utilities are subject to mandatory reliability requirements enforced through the North American Electric Reliability Corporation (NERC) Critical Infrastructure Protection standards, while other sectors face different federal, state or industry-specific requirements. Some requirements are mandatory, while others provide voluntary guidance or best practices. Federal cyber incident reporting requirements also apply to certain covered organizations. For cybersecurity professionals, this means regulatory knowledge is sector-specific and can be an important part of working in critical infrastructure security.
How do you get into critical infrastructure cybersecurity?
You can get into critical infrastructure cybersecurity by building a foundation in cybersecurity and then developing knowledge of the technologies and operational environments used in a specific infrastructure sector. Relevant skills can include networking, industrial control systems, incident response, risk management and security frameworks. Experience in IT, engineering, automation, industrial operations or cybersecurity can provide a pathway into OT security, although the most relevant background depends on the role. Certifications and training in areas such as industrial control systems security can also help demonstrate specialized knowledge. Because critical infrastructure organizations operate across sectors with different technologies and requirements, learning the operational and regulatory environment of your target industry can be as important as developing general cybersecurity skills.
