Cet article sera utile à ceux qui connaissent les technologies Check Point pour l'émulation de fichiers ( Threat Emulation ) et le nettoyage proactif des fichiers ( Threat Extraction ) et qui souhaitent franchir une étape vers l'automatisation de ces tâches. Check Point dispose d'une API de prévention des menaces qui fonctionne à la fois dans le cloud et sur les appareils locaux, et est fonctionnellement identique à la vérification des fichiers dans les flux de trafic web / smtp / ftp / smb / nfs . Cet article est en partie l'interprétation par l'auteur d'un ensemble d'articles de la documentation officielle, mais construit sur ma propre expérience opérationnelle et sur mes propres exemples. Vous trouverez également dans l'article les collections Postman de l'auteur pour travailler avec l'API Threat Prevention.
