Does Security Observability Really Need eBPF?

Extended Berkeley Packet Filters (eBPF) are valuable tools for gathering significant volumes of telemetry data from the Linux kernel, aiding in security tasks such as detecting stealthy attacks. While eBPF is effective for capturing detailed data, its utility varies based on system manageability, with "unmanageable" systems like containers requiring less telemetry and manageable systems like servers needing more extensive data collection. Observe offers a platform to handle this data efficiently through resource-aware and temporal Explorers, enhancing the understanding of systems for security purposes. The article emphasizes the importance of Security Observability, using tools like eBPF and AI to infer risk and monitor behavior, but cautions against over-reliance on telemetry in situations where simpler sampling may suffice. By leveraging AI techniques, organizations can enhance data analysis, focusing efforts on critical systems while balancing cost and resource allocation.
