\n Comprendre la s\u00e9curit\u00e9 du casque<\/strong>
\n<\/span><\/h2>\n

Quelles sont vos consid\u00e9rations principales lorsque vous s\u00e9lectionnez un casque Bluetooth ? Pour la plupart des acheteurs, soit ses inscriptions, le confort, la contrainte de forme, les fonctionnalit\u00e9s, les ins\u00e9it\u00e9s, le style de connexion, ou la compatibilit\u00e9 avec les applications et les p\u00e9riph\u00e9riques. Cependant, un \u00e9l\u00e9ment critique pas trop d\u2019acheteurs s\u2019arr\u00eatent de penser \u00e0 quel type de fonctionnalit\u00e9s de s\u00e9curit\u00e9, s\u2019il y en a, sont sur le casque. Par exemple, 85 % 1 des utilisateurs pensent que Bluetooth fournit des communications s\u00e9curis\u00e9es, mais dans le monde<\/sup> ioT d\u2019aujourd\u2019hui, les menaces sont plus sophistiqu\u00e9es. La plupart des personnes consid\u00e9rent les casques comme des p\u00e9riph\u00e9riques de base qui fournissent des fonctionnalit\u00e9s nice et se connectent \u00e0 nos smartphones ou ordinateurs portables ; cependant, ils jouent en fait une partie int\u00e9grante de la fourniture de communications s\u00fbres et fiables. Comme pour les autres dispositifs smart, les casques les plus modernes ex\u00e9cutent des logiciels complexes, les laissant vuln\u00e9rables aux attaques si ceux-ci ne sont pas correctement s\u00e9curis\u00e9s, en particulier avec la quantit\u00e9 de donn\u00e9es qui se d\u00e9place entre les p\u00e9riph\u00e9riques appari\u00e9s.<\/p>\n

Nous avons tous vu les utilisateurs mettre un objet de bande pour couvrir leur webcam, ou peut-\u00eatre vous l\u2019avez m\u00eame fait vous-m\u00eame. Plus d\u2019utilisateurs s\u2019inqui\u00e9tent \u00e9galement au sujet du hack des micros de leurs p\u00e9riph\u00e9riques. Les casques peuvent \u00e9galement \u00eatre hack\u00e9s pour effectuer des op\u00e9rations impr\u00e9vues telles que des changements de volume et sauter des pistes vers des attaques plus s\u00e9rieuses telles que l\u2019enregistrement de votre audio et la vol d\u2019informations personnelles.<\/p>\n


\n Vuln\u00e9rabilit\u00e9s critiques dans la s\u00e9curit\u00e9 de Bluetooth<\/strong>
\n<\/span><\/h2>\n

Une \u00e9quipe de chercheurs a r\u00e9cemment expos\u00e9 une vuln\u00e9rabilit\u00e9 dans des chips Bluetooth plus anciennes, appel\u00e9e l\u2019attaque UX. Sans obtenir trop d\u2019aspects techniques, cette vuln\u00e9rabilit\u00e9 astuces le p\u00e9riph\u00e9rique qui re\u00e7oit pour n\u00e9gocier un niveau de s\u00e9curit\u00e9 beaucoup plus bas. G\u00e9n\u00e9ralement, les connexions et \u00e9changes Bluetooth sont chiffr\u00e9s et bien qu\u2019il faut des mille milliards d\u2019essais pour forcer une cl\u00e9 \u00e0 128 bits, cela peut prendre quelques secondes seulement si une touche plus courte est n\u00e9goci\u00e9e. \u00c0 l\u2019issue d\u2019un attaque, capable de hacker la connexion et d\u2019\u00e9couter.<\/p>\n


\n Casques Cisco \u2014 Poser des nouvelles fondations pour la s\u00e9curit\u00e9\u00a0\u00a0<\/strong>
\n<\/span><\/h2>\n

Aujourd\u2019hui, les casques Cisco sont d\u00e9ploy\u00e9s dans les organisations gouvernementales, de soins de sant\u00e9, financi\u00e8res et juridiques qui ont certaines des politiques de confidentialit\u00e9 et de s\u00e9curit\u00e9 les plus s\u00e9v\u00e8res. Cependant, en raison des menaces en suspens sur la s\u00e9curit\u00e9, les casques Bluetooth n\u2019ont pas encore \u00e9t\u00e9 adopt\u00e9s dans les soci\u00e9t\u00e9s et les agences f\u00e9d\u00e9rales qui g\u00e8rent les informations confidentielles. La demande des p\u00e9riph\u00e9riques sans fil augmente \u00e0 un taux rapide dans ce secteur et ces agences se tournent vers Cisco pour cr\u00e9er des casques Bluetooth qui ont le plus haut niveau de s\u00e9curit\u00e9 requis et les fonctionnalit\u00e9s sur le march\u00e9 aujourd\u2019hui (par exemple, restreindre l\u2019appairement aux p\u00e9riph\u00e9riques fournis par le employeur ou n\u00e9cessitant un pin unique pour l\u2019appairer aux p\u00e9riph\u00e9riques).<\/p>\n

\u00ab Ce qui a attirer mon attention sur les casques Cisco sont les fonctionnalit\u00e9s de s\u00e9curit\u00e9 avanc\u00e9es et surtout, les fonctions d\u2019administration backend. Le travail que fait l\u2019\u00e9quipe Cisco facilitera l\u2019adoption des casques Bluetooth en particulier par des agents de s\u00e9curit\u00e9 qui sont familiaris\u00e9s avec la s\u00e9curit\u00e9 de Cisco sur leurs t\u00e9l\u00e9phones et autres points d\u2019acc\u00e8s.\u00a0\u00bb <\/em><\/p>\n

La s\u00e9curit\u00e9 a \u00e9t\u00e9 int\u00e9gr\u00e9e au c\u0153ur du casque Cisco 730, notre casque Bluetooth premium.\u00a0Dans le monde d\u2019aujourd\u2019hui, les menaces changent constamment et nous investirons continuellement pour maintenir la s\u00e9curit\u00e9 des communications. Tous nos produits passeront par le cycle de vie de Cisco Secure Development Lifecycle (CSDL), une entit\u00e9 ind\u00e9pendante qui applique les pratiques et la technologie \u00e0 tous les stades du processus de d\u00e9veloppement pour construire des solutions fiables et agir en tant que protection avant que n\u2019importe quel produit ne soit<\/a> commercial. Le d\u00e9veloppement du casque 730 n\u2019\u00e9tait pas diff\u00e9rent de celui du secteur d\u2019abord, avec une protection mat\u00e9rielle et logicielle de niveau professionnel gr\u00e2ce \u00e0 une authentification s\u00e9curis\u00e9e au d\u00e9marrage et \u00e0 l\u2019image.<\/p>\n


\n S\u00e9curit\u00e9 inh\u00e9rente du logiciel<\/strong>
\n<\/span><\/h2>\n

Le microprogramme du micro-casque est chiffr\u00e9 par Cisco avec cl\u00e9 AES 128 bits et seules les images v\u00e9rifi\u00e9es peuvent \u00eatre install\u00e9es. Il n\u2019y a \u00e9galement aucune provision pour ignorer cette protection. Ceci garantit l\u2019int\u00e9grit\u00e9 du microprogramme et minimise la possibilit\u00e9 d\u2019une installation de code malveillant.<\/p>\n


\n Protection contre le hack physique<\/strong>
\n<\/span><\/h2>\n

En plus de v\u00e9rifier le microprogramme install\u00e9, le casque 730 est \u00e9galement valid\u00e9 \u00e0 chaque processus de d\u00e9marrage en utilisant son syst\u00e8me AES-CCM Digest. Ceci permet d\u2019assurer que le p\u00e9riph\u00e9rique est authentifi\u00e9 et nonmodifi\u00e9 m\u00eame si les indies acc\u00e8dent physiquement au p\u00e9riph\u00e9rique. Cette fonctionnalit\u00e9 est \u00e9galement activ\u00e9e par d\u00e9faut et il n\u2019y a aucune fonction pour ignorer ou d\u00e9sactiver.<\/p>\n


\n Gestion intelligente et int\u00e9gr\u00e9e des casques<\/strong>
\n<\/span><\/h2>\n

Vous assurer que votre casque fonctionne sur le microprogramme le plus r\u00e9cent vous aidera \u00e0 avoir le plus haut niveau de protection contre les attaques. Les personnes les plus vuln\u00e9rables, qui traitent des informations sensibles, sont souvent celles qui n\u2019ont pas le temps de g\u00e9rer ou d\u2019am\u00e9liorer leurs casques.\u00a0 Avec les fonctionnalit\u00e9s de gestion int\u00e9gr\u00e9es de Cisco, les casques peuvent \u00eatre d\u00e9ploy\u00e9s, configur\u00e9s et contr\u00f4l\u00e9s sans probl\u00e8me par les administrateurs IT pour s\u2019assurer que le microprogramme du micro-casque est \u00e0 jour… aucune action requise de l\u2019utilisateur final.<\/p>\n

Cisco est en train de poser des nouvelles bases pour la s\u00e9curit\u00e9 du casque et nous y investirons continuellement car les risques li\u00e9s \u00e0 la s\u00e9curit\u00e9 \u00e9volution toujours dans le monde moderne d\u2019aujourd\u2019hui. Notre vision est de construire des casques de communication unifi\u00e9e de niveau professionnel qui ont la technologie la plus r\u00e9cente, la technologie moderne, et qui aident \u00e0 fournir des communications s\u00e9curis\u00e9es et fiables qui peuvent \u00eatre utilis\u00e9es dans tous les environnements ou secteurs.<\/p>\n
