Information technology — Security techniques — Evaluation criteria for IT security — Part 3: Security assurance components

ISO/IEC 15408-3:2008 defines the assurance requirements of the evaluation criteria. It includes the evaluation assurance levels that define a scale for measuring assurance for component targets of evaluation (TOEs), the composed assurance packages that define a scale for measuring assurance for composed TOEs, the individual assurance components from which the assurance levels and packages are composed, and the criteria for evaluation of protection profiles and security targets. ISO/IEC 15408-3:2008 defines the content and presentation of the assurance requirements in the form of assurance classes, families and components and provides guidance on the organization of new assurance requirements. The assurance components within the assurance families are presented in a hierarchical order.

Technologies de l'information — Techniques de sécurité — Critères d'évaluation pour la sécurité TI — Partie 3: Composants d'assurance de sécurité

La présente partie de l'ISO/IEC 15408 définit les exigences d'assurance de l'ISO/IEC 15408. Elle comprend les niveaux d'assurance de l'évaluation (Évaluation Assurance Level, EAL) qui définissent une échelle pour mesurer l'assurance pour les cibles d'évaluation (Targets of Évaluation, TOE) des composants, les paquets d'assurance composés (Composed Assurance Packages, CAP) qui définissent une échelle pour mesurer l'assurance des TOE composées, les composants individuels d'assurance à partir desquels sont composés les niveaux et les paquets d'assurance, et les critères pour l'évaluation des profils de protection (Protection Profiles, PP) et des cibles de sécurité (Security Targets, ST).
