La s\u00e9curit\u00e9 du WiFi monte d'un cran gr\u00e2ce au WPA 3, ou WiFi Protected Access 3, nouveau protocole d'authentification sur les r\u00e9seaux sans fil. WiFi Alliance vient d'officialiser cette grosse mise \u00e0 jour de s\u00e9curit\u00e9, la premi\u00e8re du genre depuis 2005. Les fabricants de routeur et box internet pourront d\u00e9sormais l'int\u00e9grer \u00e0 leurs nouveaux produits, et publier des mises \u00e0 jour du firmware pour les routeurs existants. Le protocole WPA 2 avait \u00e9t\u00e9 compl\u00e8tement contourn\u00e9 par une grave faille de s\u00e9curit\u00e9 nomm\u00e9e KRACK, permettant \u00e0 n;importe quel hacker de s'introduire sur un r\u00e9seau sans fil \u00e0 l'insu de ses utilisateurs en quelques secondes.\u00a0<\/strong><\/p>\n

\"wpa<\/p>\n

Apr\u00e8s plusieurs mois de tests, WiFi Alliance vient d'officialiser le nouveau protocole de s\u00e9curit\u00e9 WPA 3. Le successeur du WPA 2 a la lourde mission de rendre \u00e0 nouveaux les r\u00e9seaux sans fil un tant soit peu s\u00e9curis\u00e9s, apr\u00e8s qu'une grave faille de s\u00e9curit\u00e9, KRACK, ait \u00e9t\u00e9 d\u00e9couverte en octobre 2017<\/a>. Cette faille permet \u00e0 n'importe quel hacker de casser la s\u00e9curit\u00e9 des r\u00e9seaux sans fil, quelque soit le mot de passe, ou le chiffrement associ\u00e9 \u00e0 une cl\u00e9 WPA 2. Bref, instantan\u00e9ment, les r\u00e9seaux sans fil pr\u00e9sents partout sont devenus accessibles \u00e0 de nombreuses personnes mal intentionn\u00e9es. La faille KRACK est li\u00e9e au coeur du WPA 2 lanc\u00e9 en 2004, le 4-way handshake, autrement dit les \u00e9changes chiffr\u00e9s entre les clients et le routeur. Une faille impossible \u00e0 colmater totalement sans revoir profond\u00e9ment le design de la s\u00e9curit\u00e9 des r\u00e9seaux sans fil.<\/p>\n
