About the job

The postdoctoral fellowship position is a temporary position where the main goal is to qualify for work in senior academic positions.

A safety instrumented system (SIS) is a protection layer that shuts down a chemical, nuclear, electrical, or mechanical system, or part of it, if a hazardous condition is detected. For example, a process upset that is not managed by the distributed control system (DCS) or a pipe rupture are examples of events managed by the SIS. A SIS is composed of dedicated sensors, logic solvers, and final control elements (e.g., valves, relays, actuators) which are all designed fail-safe, to ensure that the SIS is able enter a safe state even upon certain fault conditions. Examples of SIS include Emergency Shutdown Systems, Emergency Venting systems, Process shutdown Systems and High-integrity Pressure Protection systems. The consequences of SIS failure can, in the worst case, be a major accident involving losses of people and damages to the environment and infrastructures.

A SIS is expected to operate independently of other systems, e.g., that a failure of the DCS system should have no negative impact on the ability of the SIS to perform as required. However, SIS systems are usually connected to the same operational technology (OT) network as systems used for control, like the DCS. The OT network may also be accessed from the outside, via the companies’ IT network and the use of secured zones for authorization, restrictions on data flow, and encryption.

The design and operation of SIS is based on regulatory requirements and framed by standards on functional safety, such as IEC 61508, IEC 61511, and IEC 62061/ISO 13849. The focus of these standards is on safety integrity, meaning the ability to perform in response to random and non-deliberate events that can arise during operation and maintenance. However, SIS devices are relying on commercial off the shelf components, and the safety certification is not necessarily providing technical solutions that are resistant to cyber-attack. For example, the Triton/Trisis attack in 2017, has shown the willingness of advanced attackers to attack SIS systems where the outcome could have been, if successful, a complete disaster at the plant. The attackers were able to create a bypass of the key switch whose position could have prevented unauthorized downloading of code to the controllers.

Industry has developed several standards applicable for distributed control and safety systems in response to the increasing risks of attack to industrial control and safety systems, like DCS and SIS. Some are general for all systems within OT networks, like IEC 62443 and NIST framework for cybersecurity, while others are specific for SIS, like ISA 84.00.09. Despite this effort, the SIS systems are exposed to many threats and experiencing new vulnerabilities, as the capabilities of the threat actors are developing.

The position creates an opportunity for more collaboration with other research disciplines such as security management, safety engineering, and policymaking in addition to the focus areas mentioned above.

The research will be carried out within the context of SFI NORCICS, the research-based innovation Norwegian Center for Cybersecurity in Critical Sectors. These sectors include electricity production and distribution, oil & gas production and distribution, manufacturing, healthcare, industrial production, smart districts. NORCICS follows a holistic, comprehensive and systemic approach addressing people, processes and technology to protect critical sectors throughout the cybersecurity core functions (identify, protect, detect, respond, recover). NORCICS has partners from academia, research, the public sector, and the industry.

The position’s working place is NTNU campus in Gjøvik. You will report to the Head of the Department.

Your immediate leader is the Head of the Department of Information Security and Communication Technology.

Duties of the position

The main objective of this postdoc position is to propose and validate a framework for managing the cyber-security of SIS and which ensures that measures implemented for enhanced safety are also cyber-secure.

The postdoctoral research fellow will:

• Contribute to the research tasks to address in this research, that include:
  • Identification of new and learning from past attack scenarios on SIS, and assessment of their local (SIS) and global (plant) impacts on safety and outage.
  • Identification and assessment of cyber-risks associated with commonly applied (commercial) SIS systems, focusing on potential vulnerabilities in hardware, firmware, and software implementation that follow safety certification and/or following general technology development with smart instrumentation, autonomy, and industrial internet of things (IIoT).
  • Development of measures for identified vulnerabilities and demonstrate their feasibility and efficiency in collaboration with industry partners. Examples of measures can relate to protection of code, protection of data flows using diodes, and protection against unauthorized downloading, such as key switches.
  • Comparing proposed measures with existing industry practices on cybersecurity measures targeting SIS in specific, with basis in cybersecurity standards from NIST, IEC 62443, and ISA 84.00.09.
  • Summarizing the results into a framework, for example as a guideline, on improved management of cybersecurity of SIS.
    More specific examples of topics relating to the research challenges have been identified with the involved partners and will be reviewed and considered in the detailed planning of the project.
• Contribute to the development of the communication and dissemination strategy of SFI NORCICS.
• Contribute to the development of research and education in Critical Infrastructure Security and Resilience by leading and supporting new research and innovation.
• Work on initiating, organizing, writing proposals for, coordinating, and carrying out national and international R&I projects of high quality, to be funded by national and international sources e.g. the NFR (The Research Council of Norway), and the European Commission.
