SECUTIL – Security and cybersecurity solutions to protect critical infrastructure

The Research Centre for Supervision, Security and Automatic Control (CS2AC) has participated in the SECUTIL project through which a comprehensive security chain management system has been created for networks and infrastructure that supply utilities (such as water, gas and electricity). The system improves physical security, access control and cybersecurity.

CS2AC has developed algorithms to detect cyberphysical attacks (for example, to detect images in a security circuit that appear normal but have been introduced by attackers, when the real images would show intruders accessing the facilities) and technologies that increase resilience to attacks. The detection technologies are based on watermarking signals, which add copyright information or other verification messages to digital documents and show whether images have been altered by an attacker. In addition, algorithms have been developed that can be used to reconfigure the control algorithm once an attack has been detected and isolated, using tolerant control technologies. All these technologies are being tested in laboratory studies and pilot tests in real environments.

As part of the project, cryptographic solutions have been developed to ensure the security and privacy of personal data throughout the service and technology cycle. This reduces the window of risk for critical infrastructure information systems. In addition, simulation tools have been designed and implemented to assist in decision-making by the critical infrastructure’s security management team and new systems and infrastructure security models have been researched.
