\"SR820<\/h4>\n

Un ami m'a pos\u00e9 une question \u00e0 ce sujet, je vais donc l'expliquer \u00e0 tout le monde. Il s'agit essentiellement de la s\u00e9curit\u00e9 de l'authentification du routeur CPE.<\/p>\n

Qu'est-ce que Routeur CPE<\/a>?<\/h2>\n

CPE = Customer Premises Equipment (\u00e9quipement des locaux du client), c'est-\u00e0-dire les appareils du client, comme les routeurs, les modems et les points d'acc\u00e8s sans fil que nous utilisons \u00e0 la maison. Ces appareils constituent la premi\u00e8re ligne de d\u00e9fense de la s\u00e9curit\u00e9 du r\u00e9seau, un peu comme votre porte d'entr\u00e9e : si cette porte n'est pas solide, toutes les autres d\u00e9fenses sont inutiles.<\/p>\n

Contre quoi la s\u00e9curit\u00e9 de l'authentification prot\u00e8ge-t-elle ?<\/h2>\n

La principale menace \u00e0 laquelle les appareils CPE sont confront\u00e9s aujourd'hui est la faiblesse des m\u00e9canismes d'authentification.<\/p>\n

    \n
  • Mots de passe par d\u00e9faut : De nombreux appareils sont livr\u00e9s avec des mots de passe faibles tels que admin\/admin - des trucs de nuls.<\/li>\n
  • Usurpation d'adresse MAC : Certains appareils ne s'appuient que sur l'authentification de l'adresse MAC, mais cette saloperie a un format fixe et est facilement falsifiable. Certificats de cryptage faibles : L'utilisation de cl\u00e9s cod\u00e9es en dur, de mots de passe courts ou de certificats auto-sign\u00e9s revient \u00e0 se mettre en mode commando Que se passe-t-il lorsque vous vous faites pirater ?<\/li>\n<\/ul>\n

    Une fois l'authentification viol\u00e9e, les cons\u00e9quences sont graves :<\/p>\n

      \n
    • Fuite d'informations personnelles : Nom, anniversaire, adresse, t\u00e9l\u00e9phone, courriel, num\u00e9ros d'identification - tout est grill\u00e9<\/li>\n
    • Attaques contre les infrastructures de r\u00e9seau : Les pirates informatiques peuvent utiliser des informations d'identification l\u00e9gitimes pour p\u00e9n\u00e9trer profond\u00e9ment dans les syst\u00e8mes dorsaux des FAI : Les logiciels malveillants peuvent provoquer des pannes de r\u00e9seau Comment renforcer la s\u00e9curit\u00e9 ?<\/li>\n<\/ul>\n

      M\u00e9thodes de renforcement pratiques:1. Politique de mot de passe fort Au moins 12 caract\u00e8res avec des majuscules + des chiffres + des symboles. N'utilisez pas de mots de passe stupides tels que des dates de naissance ou des num\u00e9ros de t\u00e9l\u00e9phone.2. mises \u00e0 jour du chiffrement<\/p>\n

        \n
      • Les appareils sans fil doivent utiliser WPA2 ou WPA3 - le WEP et l'ancien WPA ont \u00e9t\u00e9 compl\u00e8tement pirat\u00e9s Segmentation du r\u00e9seau** Utilisez des r\u00e9seaux locaux virtuels pour isoler les diff\u00e9rents appareils. Placez les appareils IoT sur un segment de r\u00e9seau distinct - ne laissez pas vos toilettes intelligentes se connecter \u00e0 votre r\u00e9seau informatique. D\u00e9sactiver les services inutiles** Fermez tous les ports et services inutilis\u00e9s. Chaque port ouvert est un point d'entr\u00e9e potentiel<\/li>\n<\/ul>\n

        5. Mises \u00e0 jour r\u00e9guli\u00e8res des microprogrammes Installez rapidement les correctifs de s\u00e9curit\u00e9 des fabricants. Ne soyez pas paresseux \u00e0 ce sujet ENSHANG R\u00e9sum\u00e9La s\u00e9curit\u00e9 de l'authentification CPP consiste essentiellement \u00e0 fortifier votre passerelle r\u00e9seau. Avec l'environnement r\u00e9seau de plus en plus complexe d'aujourd'hui et les appareils IoT partout, si la d\u00e9fense de votre routeur n'est pas solide, l'ensemble de votre r\u00e9seau interne est en danger.Amis membres du forum, rappelez-vous : La s\u00e9curit\u00e9 n'est pas une blague, la configuration n\u00e9cessite de la prudence. Ne soyez pas paresseux avec les configurations par d\u00e9faut - durcissez ce qui a besoin d'\u00eatre durci !<\/p>","protected":false},"excerpt":{"rendered":"
