Avec l’essor du travail à distance et l’adoption généralisée des technologies cloud, il est devenu primordial pour les professionnels de l’informatique du monde entier de garantir la sécurité des terminaux. Pourvoir détecter les logiciels d’accès à distance est une préoccupation majeure, car il constitue souvent le point d’entrée des personnes malveillantes.
Contexte
Les outils d’accès à distance existent depuis un certain temps. S’ils peuvent être extrêmement utiles pour le dépannage et les tâches administratives à distance, ils peuvent également être exploités par des pirates informatiques pour obtenir un accès non autorisé aux systèmes. Il est essentiel pour les professionnels de l’informatique et les fournisseurs de services gérés (MSP) de comprendre comment détecter les logiciels d’accès à distance. Ils constituent la première ligne de défense contre les failles de sécurité potentielles et l’accès non autorisé aux données.

Description détaillée
La détection d’un logiciel d’accès à distance comporte quelques étapes essentielles :
- Surveillance du trafic sur le réseau: Commencez par surveiller le trafic sur le réseau. Des schémas inhabituels ou des adresses IP inconnues peuvent être des indicateurs.
- Processus et tâches du système: La vérification régulière des processus actifs du système peut aider à identifier les outils non autorisés. Tout processus non familier doit faire l’objet d’une enquête plus approfondie.
- Audit logiciel: En utilisant des outils système intégrés tels que le « Gestionnaire de tâches » pour Windows ou le « Moniteur d’activité » pour macOS, vous pouvez obtenir une liste de toutes les applications installées. La recherche de logiciels inconnus peut parfois révéler la présence d’outils d’accès à distance.
Cas d’utilisation potentiels
Prenons l’exemple d’Alex, informaticien dans une entreprise de taille moyenne. Il remarque que la bande passante du réseau augmente en dehors des heures de travail. Après enquête, il identifie une adresse IP inconnue qui accède régulièrement à leur réseau. À l’aide d’outils d’audit du système, il découvre un logiciel d’accès à distance installé sur plusieurs systèmes bureautiques et dont personne ne se souvient de l’avoir installé. En identifiant et en supprimant ce logiciel, Alex a déjoué une violation potentielle des données.
Comparaisons
Les méthodes traditionnelles de détection des outils d’accès à distance comprennent les audits manuels, la vérification des journaux de pare-feu ou l’utilisation de logiciels antivirus. Bien que ces méthodes peuvent être efficaces, elles ne sont pas infaillibles. L’approche du script automatise le processus de détection, ce qui le rend à la fois complet et rapide. Cette méthode proactive permet souvent de détecter les logiciels d’accès à distance plus récents et plus sophistiqués qui pourraient contourner les méthodes conventionnelles.
FAQ
- À quelle fréquence dois-je vérifier les outils d’accès à distance ?
Régulièrement, surtout si vous travaillez dans un environnement qui installe et teste fréquemment de nouveaux logiciels. - Cette méthode de détection permet-elle d’identifier tous les logiciels d’accès à distance ?
Bien qu’elle soit complète, aucune méthode n’est infaillible. Il est essentiel de combiner plusieurs approches pour garantir une sécurité solide.
Le point de vue de Gavin
Il est essentiel de pouvoir détecter l’installation d’un logiciel à distance non approuvé sur une machine pour assurer la sécurité des appareils, du réseau et des données de l’entreprise.
L’informatique fantôme (shadow IT) fait référence aux systèmes, appareils, logiciels ou applications qui sont utilisés et gérés en dehors du champ d’action officiel du service informatique de votre entreprise. Cela se produit généralement lorsque les employés utilisent leurs propres solutions ou technologies sans approbation ou supervision explicite. Dans ce cas, tout logiciel à distance installé à l’insu de l’entreprise est un exemple de Shadow IT. Lorsque cela se produit, plusieurs défis majeurs se présentent :
- Manque de supervision de la part du département informatique : Lorsqu’un logiciel d’accès à distance est installé à l’insu de l’utilisateur sur un ou plusieurs appareils, il contourne souvent les protocoles standard de sécurité, de gouvernance des données et de conformité qui peuvent être mis en place dans l’entreprise.
- Risques liés à la sécurité : Étant donné que le logiciel d’accès à distance n’a pas été soumis aux mêmes mesures de sécurité que les ressources informatiques autorisées, il peut introduire des vulnérabilités (le département informatique ne peut pas corriger un logiciel dont il n’a pas connaissance) qui peuvent potentiellement entraîner des violations de données ou des incidents de sécurité
- Risque lié au fournisseur : Certains fournisseurs disposent de meilleures couches de sécurité que d’autres. L’introduction de logiciels, en particulier de logiciels d’accès à distance dont les fournisseurs n’ont pas fait l’objet d’un contrôle approprié, peut présenter des risques supplémentaires pour l’organisation, voire lui faire courir le risque d’échouer aux évaluations de conformité ou de sécurité
Ce script peut aider en détectant une liste connue de logiciels d’accès à distance et en se déclenchant lorsqu’il détecte un logiciel qui ne figure pas dans la liste de ceux autorisés. Au-delà des questions de sécurité, ce type de détection présente d’autres avantages :
- Pour les entreprises MSP, il peut s’agir d’une bonne indication que votre client est en train de s’engager avec une autre MSP ou une entreprise informatique
- Il peut aider à identifier les restes d’anciens logiciels d’accès à distance installés sur le réseau
Conclusions
Un logiciel d’accès à distance non détecté peut entraîner des failles importantes, des vols de données, voire des attaques par ransomware. Étant donné que de plus en plus d’entreprises migrent en ligne, assurer la sécurité de chaque point d’accès devient une tâche fondamentale. Ne pas prendre cela au sérieux pourrait avoir des répercussions financières, opérationnelles et de réputation.
