WordPress<\/a> est l'un des syst\u00e8mes de gestion de contenu (CMS) les plus r\u00e9pandus au monde. Toutefois, en raison de sa popularit\u00e9, il est \u00e9galement une cible fr\u00e9quente pour les pirates informatiques. Dans cet article, vous apprendrez comment s\u00e9curiser efficacement votre installation WordPress.<\/p>\n

Pourquoi WordPress est-il une cible d'attaque ?<\/h2>\n

La grande diffusion de WordPress le rend attractif pour les pirates qui tentent d'exploiter des failles de s\u00e9curit\u00e9 connues. Les attaques automatis\u00e9es v\u00e9rifient syst\u00e9matiquement si une installation WordPress est obsol\u00e8te ou pr\u00e9sente des vuln\u00e9rabilit\u00e9s. Il est donc essentiel de maintenir votre syst\u00e8me \u00e0 jour.<\/p>\n

Un h\u00e9bergeur web professionnel avec int\u00e9gration Pare-feu<\/a> peut offrir une protection suppl\u00e9mentaire. Si vous n'avez pas le temps d'effectuer r\u00e9guli\u00e8rement les mises \u00e0 jour vous-m\u00eame, vous devriez envisager de faire appel \u00e0 une soci\u00e9t\u00e9 de conseil en s\u00e9curit\u00e9 informatique. Agence<\/a> r\u00e9fl\u00e9chir.<\/p>\n

Garder WordPress en s\u00e9curit\u00e9 - Les mesures les plus importantes<\/h2>\n

1. mettre \u00e0 jour r\u00e9guli\u00e8rement WordPress et les plugins<\/h3>\n
    \n
  • Activez la mise \u00e0 jour automatique, si possible.<\/li>\n
  • Connectez-vous r\u00e9guli\u00e8rement au tableau de bord de WordPress et v\u00e9rifiez les mises \u00e0 jour en attente.<\/li>\n
  • Faites particuli\u00e8rement attention aux th\u00e8mes premium qui doivent souvent \u00eatre mis \u00e0 jour manuellement.<\/li>\n<\/ul>\n

    2. utiliser des connexions s\u00e9curis\u00e9es<\/h3>\n
      \n
    • Utilisez un certificat SSL pour votre site web, afin que l'acc\u00e8s soit toujours possible via https:\/\/<\/strong> a lieu.<\/li>\n
    • Utilisez des connexions s\u00e9curis\u00e9es pour les consultations de courrier \u00e9lectronique et les acc\u00e8s FTP.<\/li>\n
    • Si vous avez d\u00e9j\u00e0 utilis\u00e9 une connexion non crypt\u00e9e, changez imm\u00e9diatement tous vos mots de passe.<\/li>\n<\/ul>\n

      3. s\u00e9curiser le wp-login.php<\/h3>\n
        \n
      • Configurez une demande de mot de passe suppl\u00e9mentaire pour le r\u00e9pertoire d'administration.<\/li>\n
      • Utilisez une .htaccess<\/code>-Verrouillage pour emp\u00eacher les acc\u00e8s non autoris\u00e9s.<\/li>\n<\/ul>\n

        4. prot\u00e9ger le r\u00e9pertoire d'administration de WordPress<\/h3>\n

        Outre la s\u00e9curisation de la page de connexion, vous devriez \u00e9galement prot\u00e9ger l'ensemble du r\u00e9pertoire d'administration :<\/p>\n

          \n
        • Activez le Protection du r\u00e9pertoire<\/strong> chez votre h\u00e9bergeur.<\/li>\n
        • Choisissez un mot de passe s\u00fbr d'au moins 12 caract\u00e8res, y compris les caract\u00e8res sp\u00e9ciaux.<\/li>\n
        • Compl\u00e9tez les .htaccess<\/code>-Le fichier de donn\u00e9es de l'utilisateur contient des m\u00e9canismes de protection contre les acc\u00e8s non autoris\u00e9s :<\/li>\n<\/ul>\n
          \r\nErrorDocument 401 \"Bloqu\u00e9\"\r\nErrorDocument 403 \"verrouill\u00e9\r\n\r\n# Autoriser l'acc\u00e8s des plugins \u00e0 admin-ajax.php malgr\u00e9 la protection par mot de passe\r\n\r\nOrder allow,deny\r\nAllow from all\r\nSatisfy any\r\n<\/pre>\n
          5. choisir des plugins et des th\u00e8mes s\u00fbrs<\/h3>\n
            \n
          • Utiliser uniquement des plugins et des th\u00e8mes<\/strong>Les logiciels de gestion de l'information sont souvent install\u00e9s et r\u00e9guli\u00e8rement mis \u00e0 jour.<\/li>\n
          • Acheter des th\u00e8mes premium de des fournisseurs de confiance<\/strong> comme ThemeForest ou TemplateMonster.<\/li>\n
          • Faites attention \u00e0 la date de la derni\u00e8re mise \u00e0 jour d'un plugin ou d'un th\u00e8me.<\/li>\n<\/ul>\n
            \u00c9vitez les th\u00e8mes gratuits provenant de sites web inconnus, car ils sont souvent infect\u00e9s par des logiciels malveillants.<\/p>\n
            6. supprimer les plugins et les th\u00e8mes inutilis\u00e9s<\/h3>\n
              \n
            • Supprimez les plugins non utilis\u00e9s directement via l'interface de WordPress.<\/li>\n
            • Supprimez \u00e9galement manuellement les th\u00e8mes par d\u00e9faut superflus par FTP s'ils ne peuvent pas \u00eatre d\u00e9sinstall\u00e9s facilement.<\/li>\n<\/ul>\n
              7. utiliser un pare-feu applicatif<\/h3>\n
              A Pare-feu applicatif<\/strong> peut aider \u00e0 bloquer les attaques \u00e0 un stade pr\u00e9coce. Les solutions recommand\u00e9es sont<\/p>\n
                \n
              • Fail2Ban<\/strong> (gratuit, d\u00e9tecte les tentatives de connexion suspectes)<\/li>\n
              • mod_security WAF<\/strong> (Pare-feu d'application web pour bloquer les mod\u00e8les d'attaque connus)<\/li>\n
              • Les fournisseurs de pare-feu externes comme Barracuda, SonicWall ou Imperva<\/strong> (solutions professionnelles \u00e0 partir de 50-250 \u20ac par mois)<\/li>\n<\/ul>\n
                Dans le cas d'un h\u00e9bergement partag\u00e9, il est souvent impossible d'installer un pare-feu. Dans ce cas, un serveur V administr\u00e9 est une alternative plus s\u00fbre.<\/p>\n
                Conclusion : la s\u00e9curit\u00e9 dans WordPress n'a rien de sorcier<\/h2>\n
                Avec des mises \u00e0 jour r\u00e9guli\u00e8res, des mots de passe s\u00fbrs et les bonnes mesures de protection, vous pouvez s\u00e9curiser votre site WordPress de mani\u00e8re fiable. Investissez dans un h\u00e9bergement s\u00e9curis\u00e9 et \u00e9vitez les plugins et th\u00e8mes gratuits et inconnus. En respectant ces conseils, vous minimiserez consid\u00e9rablement le risque d'attaques.<\/p>","protected":false},"excerpt":{"rendered":"
