About the Job

About the position:

We are looking for a highly motivated researcher in sustainable collective time series anomaly for cyber-physical systems (CPSs) at the Department of Information Security and Communication Technology.

Anomaly detection is vital for securing CPSs by identifying deviations in real time, crucial for early detection of threats and preventing cyberattacks. It extends beyond cybersecurity, identifying faults in physical behavior, crucial for maintaining system integrity in critical contexts. Additionally, it enhances system resilience by facilitating issue identification and containment, aiding adaptation and recovery from unforeseen events.

Due to the dynamic CPS environment where the relationships between different components or variables may change over time, the ability to adapt to evolving dependencies is crucial for effective anomaly detection. In addition, as the number of time series in a CPS increase, scalability becomes an important consideration. The challenge is, how we can provide sustainable collective anomaly detection that is scalable, environmentally friendly, and capable of adapting to dynamic dependency changes, and while guaranteeing effective detection accuracy.

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.

Duties of the position

The Researcher is expected to confront the above-mentioned challenges and develop practical and applicable solutions that can be applied to real-world critical cyber-physical systems. More specifically, the Researcher is expected to:
Develop an adaptive anomaly detection approach that can effectively identify anomalies within both univariate and multivariate time series in a real-time and lightweight manner.
Develop an energy-saving mechanism that can learn the correlation between different time series and cluster these time series in a dynamic and real-time manner.
Develop a lightweight approach that can collectively identify anomalies within a large set of time series based on their dynamic correlation.
Conduct comprehensive performance evaluation of the developed approach by applying it to the CPSs provided by the project partners.

In addition, the Researcher is expected to provide teaching, and supervise students at the bachelor's, master's, and doctoral levels.
