Public services have become prime targets of hackers. In response to this observation, and to enable the continuous deployment of digital services to the user as well as the digital transformation of the administration, the Departmental Council of Cantal has embarked on a cyber-resilience project. After being part of the France Relance approach led by ANSSI, a "cyberscore" was established for the "C-" Department. The goal is to achieve the A- score through an action plan that aims to improve this score. The main objective of the operation is to significantly increase the degree of digital security of data and services to users in order to ensure the continuity of the public service and the protection of personal and / or sensitive data.
