Problematic :

 Cyberspace management involves securing critical network infrastructures through cybersecurity procedures. 

Technology has brought the management of critical infrastructures to the point where they are managed by control systems, such as the SCADA system. 

SCADA is a system of software and hardware components that enables industrial organizations such as power, energy, oil, gas and water to control industrial processes remotely, monitor, collect and process data in real time, and record events in a log file.

With the advent of highly digitized Smart Grids, the slightest flaw in any part of the SCADA system can cause exposure to a deliberate attack that can lead to system failure, property loss, and even endanger human lives.

Vulnerabilities in the overall architecture of SCADA networks can be controlled by authentication and identification in communication protocols. Another type of vulnerability may be linked to the standard or proprietary operating system. Therefore, the communication framework in the operation of collecting and analyzing activities for security monitoring of host interfaces, the characteristics of network communication protocols must comply with the security requirements of the SCADA system. Hence this study.

Objectives / Expected results : This research aims to design an efficient and reliable SCADA architecture. The aim is to exploit network telemetry concepts, with optimized placement of fault-tolerant sensor nodes with guaranteed minimum detection probability, to solve SCADA network security issues in smart grids. Network telemetry refers to the automated communication process by which measurements and other data are collected at remote points and transmitted to receiving equipment for monitoring purposes. Given the different requirements of SCADA monitoring applications, the main objective is to orchestrate the process of collecting network telemetry elements in order to maximize the number of requirements met by network monitoring applications, while taking into account different cybersecurity threats. The mathematical programming approach will be used with the design of exact techniques or metaheuristics for a more efficient and reliable SCADA architecture.

Contribution / added value to the affiliated project : As part of this project, we will propose an optimized SCADA architecture to meet the requirements of critical SCADA applications in smart power grids, taking into account the various cyber security threats. This architecture will be exploited by the project's second affiliated thesis, which will integrate a bio-inspired intrusion detection system.
