confinement mechanism for Linux using eBPF ▶ Users write per-application policy in a simple policy language ▶ Policy is enforced by attaching BPF programs to LSM hooks ▶ Integrates userspace and kernelspace uprobes, etc.) with policy enforcement (LSM probes) ▶ Rapid prototyping ▶ Safe production deployment of new security solutions We have an opportunity to rethink process confinement from the ground up. 3 / and production-safe ▶ Works out of the box on any vanilla Linux kernel ≥ 5.8 4 / 7 Our Policy Language Rules and Directives Rules specify access to system objects: ▶ fs(file, access) ▶ net(socket

tracing programs almost anywhere in kernel or user applications. eBPF is a strictly-typed assembly language with a stable instruction set. eBPF programs can be loaded and upgraded in real time without the module. Linux supports JIT compilation towards all widespread architectures. System calls Acquiring a new taste for engine room hacking, The bees developed their activities more and more. In the narrow spaces messages in their own encoding. When the bees jumped on the case, it marked the beginning Of a whole new era for data sharing and messaging. Mail was still slow to go through the ship’s processors, But the
