Osquery runs as a service via the osqueryd service.The parameters for configuring this connection to Fleet are stored in C:\Program Files\osquery\osquery.flags.The queries and configurations for the Osquery agent are supplied by Fleet over a TLS connection. In DetectionLab, Osquery agents are enrolled into Fleet.Osquery is able to introspect into many areas in the operating system, and using JOINs, it allows you to gather quite a bit of context with a single query. While many endpoint security agents collect ongoing and streaming data such as process creation and file modification, Osquery allows you to take a “point in time” examination about the state of your devices which makes searching for anomolies and outliers more straightforward. With Osquery, SQL tables represent abstract concepts such as running processes, loaded kernel modules, open network connections, browser plugins, hardware events or file hashes. New post: Setup my GoLang Osquery-file-carving server with Kolide. Osquery 1 is a cross-platform open source. A wonderful complimentary tool to osquery, query your endpoints and your cloud. This allows you to write SQL queries to explore operating system data. If you crave a unified interface for querying the different aspects of the operating system, you need osquery. Osquery exposes an operating system as a high-performance relational database. The tools make low-level operating system analytics and monitoring both performant and intuitive. Note that due to the nature of the environments that osquery runs in, the osquery agent does not listen for incoming connections. When this is enabled, osqueryd will periodically check in to a remote server to see whether there are queries for it to execute (typical intervals for this check range from 10 seconds to 1 minute). Osquery is an operating system instrumentation framework for Windows, OS X (macOS), Linux, and FreeBSD. When osquery is running in daemon mode, you can enable the distributed query facilities.
