Stéphane Corblin is responsible for the Network Architecture of the Paris Sanitation Authority (SIAAP) and his mission is to ensure the operation and security of the entity’s IT network.
Although the SIAAP is not classified as an Operator of Vital Importance (OVI) by the ANSSI, it strives to follow the rules issued by the French national cybersecurity agency. As some sites are classified as "high threshold SEVESO", infrastructure security, and in particular the control of access to water treatment equipment, is a major issue for Corblin. The main risk identified is the discharge of untreated water into nature, which poses risks to the environment.
