Enhancing Cloud-Native Security Through eBPF Technology

In the cloud industry, eBPF (extended Berkeley Packet Filter) security technology is one of the most popular and influential technologies in the Linux kernel in recent years. With the rapid development of networking and cloud-native technologies, eBPF is extensively applied in network and security, performance analysis, container and cloud-native environments, operations and troubleshooting, as well as observability of application systems. This paper focuses on the practical application of eBPF technology in cloud environments for ensuring the secure operation, event-driven security handling capability, and performance hotspots observation of transaction systems. The integration of eBPF technology significantly enhances efficiency and reduces costs across the development, testing, and operational phases of systems, providing effective means for security optimization, assisting in testing, and facilitating fault localization and troubleshooting during secure production operations. Moreover, eBPF plays a crucial role in handling security events in cloud environments.
