Resilience Week
Resilience Week

Since 2008, Resilience Week has provided an opportunity for stakeholders to understand the state of research in cyber and physical security for critical infrastructure in all 16 critical infrastructure sectors. This year, the following plenary and keynote speakers will present their perspectives on the multidisciplinary challenges associated with resilience:

Grand Challenge
Grand Challenge in Resilient Control Systems

There is a preeminent objective of corporate and government organizations for a comprehensive understanding of the security and safety of critical infrastructure, or state awareness. Enabled by this paradigm shift is the move from reactive to proactive control of plants, and mechanisms by which the evaluation and verification of designs is considered from design through implementation, resilient control systems.

Projects

Role-based, Cyber-Physical State and Context Awareness
Dynamic visualizations change how the data is represented in real time which allows users to quickly understand where changes in the system are happening, the priorities of response, the root cyber or physical cause and potential for larger, potentially cascading failures. Dynamic data visualization allows for visual representations of data that can be altered as the represented data changes. This can allow for quick and intuitive understanding of changes in the system as size, color, length, etc., is altered devices can be connected to and communicate with each other over a network. This can allow for an efficient peer-to-peer resource sharing system to be implemented across the system. Resource sharing adds an additional layer to visualization by allowing local visual implementations to change dynamically based on global data as well.
Adaptive and Agile Resilience Control Architectures
The basis of resilient threat-resilient information networks requires consideration of all threats and measures by which we determine proper operation. These measures, which can be categorized as cyber and physical security, process efficiency and stability, and process compliance, provided the operating require­ments that are monitored for situational awareness and definition of the power grid or process state. Traditional concepts of redundancy, diversity, and defense in depth that were once only considered for reliability can be broadened for application to all measures. New concepts that research the human system responses, both benevolent operator and malicious actor interactions, as well as the complex interdependencies of distributed information networks require consideration. The move from reactive to proactive control of plants and mechanisms by which the evaluation and verification of designs is considered all the way from design through implementation stages of resilient information networks is enabled by this paradigm shift.
Infrastructure Trustworthiness Assessment & Proactive Control
Untrustworthy data can lead to poor automated system control, difficulty in decision making, and frustrating end-user experiences as a minimum, but with nation state attacks, cascading outages and wide scale loss of infrastructures. This data is very often very large in scale and comes from heterogeneous sources. Moreover, information technology (IT) and operation technology (OT) operators who now find themselves responsible for cybersecurity come from a variety of backgrounds, differing decision support requirements, and knowledge capabilities. To effectively abstract the complexity of cybersecurity and simultaneously address the variety of roles, knowledge, and need, a design is needed that performs much of the required analysis for the user and presents only relevant information in a consistent way.
Intelligent Cyber Detection & Feedback Mechanisms
Traditional protections offered by intrusion detection devices are dependent on known signatures. Any “lockdown” of these devices can lead to performance effects on the automation system, as well as the production of many false positives for network security engineers to evaluate. The cyber challenge is to provide a resilient cyber feedback system that can be quickly implemented and provide diverse techniques for cyber recognition that can be analyzed based on individual networks. This system must be lightweight in its performance requirements and proactive in design, using analytics to advance modification of the automation network protections faster than the attacker can respond

Intelligent Automation

We are designing and developing predictive and advanced automation mechanisms in existing test facilities, whose concepts will be applied to next generation hybrid energy production designs. Intelligent automation research can lead to methods that couple multiple processes to ensure the safest and most efficient production.

System Integration Laboratory

A combination of connected assets that can be reconfigured to research specific topics related to technology grid-integration and hybridization. The constituents of SIL include several lab environments operated to assess several technology-specific questions. A few of the assets include low and high power electric vehicle service equipment, a microgrid with multiple generation and electrical storage assets, high temperature electrolyzers, and thermal loops capable of emulating the heat profiles from thermal power plants. These technologies are integrated through digital real time simulators and grid emulators to enable hardware testing during emulated normal and off-normal grid conditions.

Control System Cyber Resilience

​​As instrumentation and control systems become more complex, so does the relationship between human operator and the system. Resilience finds its basis in the understanding and predicting of human behavior. INL researchers have long studied this issue and continue to examine ways to improve safety and security by producing better, more user-friendly designs. A reconfigurable control room test bed allows researcher to test performance and implement the latest in sensory and visualization design based on state of the art process simulation.

Control System Security research and development covers a spectrum of ​monitoring and resilience technologies that provide additional cyber awareness of attack and resilient design mitigations to defend against compromise. Teams of control and security researchers form multidisciplinary teams to ​​develop tools, perform assessments and training, and develop cutting edge products. This research complements the development efforts of programs that include the Industrial Control System ​​Computer Emergency Readiness Team​ (ICS-CERT), funded by the Department of Homeland Security (DHS).

Cyber Awareness and Resilient Design
Because of the human element of a malicious actor, traditional methods of achieving reliability cannot be used to characterize cyber awareness and resilient design. Dynamic mechanisms of probabilistic risk analysis that can link human reliability with the system state are still maturing. The intellectual level and background of the adversary makes stochastic methods unusable due to the variability of both the objective and the motives. In addition, the strength of the adversary is increased because the existing control system architecture is not random, and response characteristics are reproducible. Therefore, a resilient design can find strength in similar fashion by becoming atypical of normal control system architectural design, and appearing random in response and characteristics to the adversary.

The R&D focus is on technologies to advance the state of the art within the area of cyber resilience, which requires a necessary paradigm shift to address the evolving threat. For cyber awareness, these include diverse, multilayered and potentially out-of-band indicators of cyber threat across the control system architecture. In addition, physical indicators of cyber compromise provide a well-understood baseline for operation. Holistically, these diverse indicators provide a trustworthy basis for quick identification and response by the human, providing more fidelity and less false positives in interpretation of cyber threat. In addition, they provide basis for more autonomous action by active defenses that include moving target design. Active recognition coupled with modification and obfuscation of the environment provides resilience to attack.

Resilient Control Systems Laboratory

The resilient control systems (RCS) hardware-in-the-loop laboratory at Idaho National Laboratory (INL) hosts inter-organizational cognitive, cyber-physical systems research area pioneered by INL, which includes technologies sponsored through Department of Energy (DOE), Department of Defense (DOD), and Department of Homeland Security (DHS) programs. The test bed provides a real world environment, segmented by project, to demonstrate the measurable benefit achieved with these new technologies over current state-of-the-art. Test procedures validate a quantitative means to demonstrate the value proposition for prospective customers. The test bed includes high fidelity emulators, in addition to numerous control system hardware and software implementations, to provide bench to lab scale piloting before applying to full scale infrastructure applications.

Human Systems Integration

​​As instrumentation and control systems become more complex, so does the relationship between human operator and the system. Resilience finds its basis in the understanding and predicting of human behavior. INL researchers have long studied this issue and continue to examine ways to improve safety and security by producing better, more user-friendly designs. A reconfigurable control room test bed allows researcher to test performance and implement the latest in sensory and visualization design based on state of the art process simulation.

Human Factors, Controls and Statistics

The Human Factors, Controls and Statistics Department is an international leader in the application of scientific methods, techniques and tools to address the performance and operational challenges of mission-critical industries. The Department employs specialized methods and state-of-the-art data analysis and modeling tools to support diverse customers in mission-critical industries to improve their decision-making, operational performance, evaluation of technology options, reliability of humans and systems, and reduction of error.​

Human System Simulation Laboratory (HSSL)

H​uman performance is the central theme in the research done in the HSSL. INL human factors researchers have extensive knowledge and experience of human performance in nuclear power operations and apply a wide range of human factors principles, methods and tools in solving practical and emerging problems in the energy sector. A large part of the HSSL is devoted to the study of human performance in a near-realistic operational context.

Frequently Asked Questions

What is a resilient control system

What are critical infrastructures (CIs)?
Critical Infrastructure Security and Resilience (CISR) includes the assets or infrastructures relevant to everyday life―from the power in our homes, the means of transportation we take to and from work, to the food and water we depend on daily. Security and resilience refers to the goals of making CIs secure and able to recover upon failures of various natures.
Why are critical infrastructures (CIs) important?
CIs are our nation’s backbone. They refer to both physical and cyber systems vital to our nation’s physical or economical security, health, and safety. CIs carry different meaning to different people. Security and resilience of CIs advances a national policy to strengthen and maintain secure, functioning, and resilient CIs.
What are some examples of critical infrastructures (CIs)?
The Presidential Policy Directive (PPD-21) and the United States (U.S.) Department of Homeland Security define CIs and what security and resilience of CIs means. PPD-21 identifies 16 CI sectors (e.g., food and agriculture, healthcare, dams, energy, financial services, government facilities, and communications). These infrastructures entail assets, systems, and networks (physical or virtual), vital to the United States and on which the nation depends.
What is security and resilience?
The Cyber Infrastructure Security Agency (CISA) defines security as reducing the risk of natural or manmade disasters to CIs. This includes both physical and cyber threats. Physical measures, such as fencing, guarding, and cyber measures such as intrusion detection systems and antivirus software measures are used to provide protections to cyber-physical threats. Resilience measures could be anything from backup power generators, business continuity plans, to software tools for anomaly detection and recovery.
