• •Exein reported a technical workflow for enabling BPF LSM (Linux Security Modules) on ARM64-based hardware using ftrace.
• •The guide confirms that ftrace can be used to trace kernel function calls and verify BPF hook points without specialized vendor hardware.
• •The feasibility of deploying these security policies at scale remains unconfirmed, as the process requires kernel-level debugging expertise and lacks standardized automation.

Exein has published a technical walkthrough for deploying BPF LSM on aarch64 systems using ftrace to monitor hook execution. While BPF-based security has become common on x86_64, the ecosystem for ARM-based implementations like this is still in its early, manual-heavy phase. However, the reliance on ftrace for validation highlights a significant barrier to entry, as debugging kernel hooks requires advanced knowledge of specific register states. Whether this method scales beyond specialized development environments depends on whether the community can standardize these tracepoints for production security monitoring.
