OpenVAS Feuilles de chaleur

- :material-content-copy: **[Copier sur le presse-papiers] (__LINK_0__)** - **[Télécharger PDF](__LINK_0__)**

Aperçu général

OpenVAS (Open Vulnerability Assessment System) est un scanner de vulnérabilité complet et une solution de gestion de vulnérabilité. Il fait partie du cadre de gestion de la vulnérabilité de Greenbone (GVM) et fournit de puissantes capacités pour identifier les vulnérabilités de sécurité dans les réseaux, les systèmes et les applications.

Caractéristiques principales

• ** Scannage complet**: Détection et évaluation de la vulnérabilité du réseau
• Extensive NVT Database: plus de 50 000 essais de vulnérabilité réseau (NVT)
• Interface Web: Assistant de sécurité pour Greenbone (GSA)
• Reportage flexible: formats de rapport multiples et options de personnalisation
• ** Numérisation de la conformité** : appui à divers cadres de conformité
• Scannage authentifié: scans reconnus pour une analyse plus approfondie
• Intégration API: API REST pour l'automatisation et l'intégration
