osquery
Operating system instrumentation framework that exposes low-level system telemetry as SQL tables for security monitoring.
Technical Architecture & Overview
osquery is an open-source endpoint telemetry framework originally developed by Facebook (Meta). It exposes operating system data as high-performance SQL tables, allowing security teams to query running processes, network connections, file hashes, and system configurations using standard SQL syntax.
Targeted Technical Use Cases
SQL-based endpoint telemetry collection, threat hunting, and compliance auditing across fleet endpoints.
Evaluation & Trade-offs
Core Strengths
- +SQL interface makes endpoint querying accessible to analysts without specialized tool knowledge.
- +Cross-platform support for Linux, macOS, and Windows from a single agent.
- +Used as the data collection layer by many EDR, SOAR, and fleet management platforms.
Trade-Offs & Limitations
- -Point-in-time queries only; does not provide continuous event streaming without additional configuration.
- -Distributed query management requires FleetDM or a custom orchestration layer.
Defensive Security Application
Fleet-wide endpoint visibility, threat hunting, and configuration compliance auditing via SQL queries.
