- Evolving the Security Paradigm for Industrial IoT EnvironmentsPublication . Rosa, Luis; Freitas, Miguel Borges de; Henriques, João; Quitério, Pedro; Caldeira, Filipe; Cruz, Tiago; Simões, PauloIn recent years, IACS (Industrial Automation and Control Systems) have become more complex, due to the increasing number of interconnected devices. This IoT (internet of things)-centric IACS paradigm, which is at the core of the Industry 4.0 concept, expands the infrastructure boundaries beyond the aggregated-plant, mono-operator vision, being dispersed over a large geographic area. From a cybersecurity-centric perspective, the distributed nature of modern IACS makes it difficult not only to understand the nature of incidents but also to assess their progression and threat profile. Defending against those threats is becoming increasingly difficult, requiring orchestrated and collaborative distributed detection, evaluation, and reaction capabilities beyond the scope of a single entity. This chapter presents the Intrusion and Anomaly Detection System platform architecture that was designed and developed within the scope of the ATENA H2020 project, to address the specific needs of distributed IACS while providing (near) real-time cybersecurity awareness.
- Towards Protecting Critical InfrastructuresPublication . Caldeira, Filipe; Cruz, Tiago; Simões, Paulo; Monteiro, EdmundoCritical Infrastructures (CIs) such as power distribution are referred to as “Critical” as, in case of failure, the impact on society and economy can be enormous. CIs are exposed to a growing number of threats. ICT security plays a major role in CI protection and risk prevention for single and interconnected CIs were cascading effects might occur. This chapter addresses CI Protection discussing MICIE Project main results, along with the mechanisms that manage the degree of confidence assigned to risk alerts allowing improving the resilience of CIs when faced with inaccurate/inconsistent alerts. The CockpitCI project is also presented, aiming to improve the resilience and dependability of CIs through automatic detection of cyber-threats and the sharing of real-time information about attacks among CIs. CockpitCI addresses one MICIE's shortcoming by adding SCADA-oriented security detection capabilities, providing input for risk prediction models and assessment of the operational status of the Industrial Control Systems.
