These teams are responsible for preventing, detecting, and responding to cyberattacks while coordinating efforts to mitigate damage.<\/p>\n\n\n<p>The first <strong>CERT<\/strong> was created in 1988 following <strong>the Morris worm attack<\/strong>, one of the first large-scale <a href=\"https:\/\/liora.io\/en\/all-about-malware\">computer viruses<\/a>. Since then, CERTs have multiplied across the globe, becoming key players in cybersecurity.<\/p>\n\n\n<p>In France, the <strong>CERT-FR<\/strong> is the governmental and national CERT. It is supported by the <strong>ANSSI<\/strong> (National Cybersecurity Agency of France) and primarily intervenes with public agencies and operators of vital importance.<\/p>\n\n\n<h2 class=\"wp-block-heading\" id=\"what-are-the-missions-of-cert-fr\">What are the missions of CERT-FR?<\/h2>\n\n\n<p>The goal of CERT-FR is to protect French information systems against <strong>cyber threats<\/strong>.
