Microsoft has returned to developing 'Hornet', a security feature for eBPF programs on Linux. The project, highlighted by Phoronix, focuses on enhancing protections for these kernel-level programs.
Microsoft engineers are once again advancing the 'Hornet' initiative, which targets security improvements for eBPF programs operating within the Linux kernel. eBPF, or extended Berkeley Packet Filter, enables efficient execution of user-defined programs in the kernel without modifying its code, and Hornet aims to bolster safeguards around this technology.
Phoronix reports that after a period of inactivity, Microsoft has picked up development efforts on Hornet. This work is part of broader contributions to Linux security, particularly for eBPF, which is widely used in networking, tracing, and security monitoring. No specific timelines or additional details on the project's progress were provided in the coverage.
The resumption of Hornet development underscores Microsoft's ongoing investment in open-source Linux technologies, despite its primary focus on Windows. eBPF has become a cornerstone of modern Linux distributions, and strengthening its security could benefit developers and system administrators relying on it for performance-critical tasks.
