WebThe concept of Trusted Execution Environments has been broadly introduced to microcontrollers with ARM’s TrustZone-M. While much experience with TrustZone-A can be applied, architectural differences with ARMv8-M lead to a very different approach to configuration and transitions between secure and non-secure worlds. WebeBPF can be used to for software defined networks, DDoS mitigation (early packet drop), improving network performance (eXpress Data Path), intrusion detection, and more. On this page I'm focusing on its use for observability tools, where it …

WebExtended Berkeley Packet Filter (eBPF) addresses both these issues. eBPF is a kernel technology (fully available since Linux 4.4). It lets programs run without needing to add additional modules or modify the kernel source code. You can conceive of it as a lightweight, sandboxed virtual machine (VM) within the Linux kernel. WebFeb 22, 2024 · As a result, enabling eBPF programs written for Linux to run on top of the eBPF for Windows platform is very important to us. In this update, we want to talk about our learning and observations using an application that was fundamentally written for Linux.
