Heuristics

Automated inference - use with caution

All attributes shown in this section (e.g., links between certificates, products, vendors, and known CVEs) are generated by automated heuristics and have not been reviewed by humans. These methods can produce false positives or false negatives and should not be treated as definitive without independent verification. For details on our data sources and inference methods, see our methodology. If you believe any information here is inaccurate or harmful, please submit feedback.

Description The TOE is the L4Re Secure Separation Kernel CC 1.0.1 (L4Re SSK). L4Re SSK is a distribution of the open-source L4Re Operating System Framework. As such it is based on the L4Re Microkernel. The L4Re Microkernel is a 3rd-generation microkernel with a state-of-the-art capability-based mandatory access control security model. It allows the separation of applications into different security domains, information flow control, and, subject to access control, dynamic assignment of resources and communication channels. Further the L4Re Microkernel supports static workloads alongside dynamic workloads, which allows to start, restart and shutdown applications during runtime. L4Re SSK is configured to act as a separation kernel, to provide the security features claimed by the ST. The TOE supports native applications as well as virtual machines (VMs). Access to every resource including but not limited to memory, hardware devices and CPU cores is protected by capabilities. Applications and VMs can only access a resource if they possess a capability with suitable permissions for that resource.
