The telemetry path is the chain that moves security data from collection points to analysis and alerting. On a Linux host, that may include kernel probes, eBPF programs, agents, local buffers, and a backend that raises an alert. If any part of that chain is changed, filtered, or disabled, the security team may never see the event.
This matters because defenders often trust telemetry to prove that a kernel module loaded, a process spawned, or a policy was violated. Attackers can target the telemetry path instead of the detector itself, tampering with maps, filters, queues, or permissions so suspicious activity is suppressed at the source. In real defenses, the response is to treat telemetry controls as security-critical state, monitor the health of the pipeline, and corroborate alerts with independent logs, process lineage, package records, and kernel indicators. A reliable detection program does not depend on one sensor alone.
