What is osquery?
Osquery is an open-source endpoint visibility tool developed by Facebook. It allows administrators to query and manage the state of their infrastructure using SQL queries. Osquery provides a powerful way to monitor, investigate, and remediate security incidents, as well as ensure compliance with security policies. With osquery, administrators can collect and analyze data from endpoints, including process lists, file systems, network connections, and more.
Main Features
Osquery provides several key features that make it a powerful tool for endpoint security and management, including:
- Endpoint Visibility: Osquery provides real-time visibility into endpoint activity, allowing administrators to monitor and analyze data from endpoints.
- SQL Querying: Osquery allows administrators to query endpoint data using SQL queries, making it easy to collect and analyze data.
- Extensibility: Osquery has a modular architecture, allowing administrators to extend its functionality with custom plugins and integrations.

Osquery Snapshot and Restore Workflow
What is a Snapshot?
A snapshot is a point-in-time image of an endpoint’s state. Osquery allows administrators to create snapshots of endpoints, which can be used to restore an endpoint to a previous state in case of a security incident or other issue.
Creating a Snapshot
To create a snapshot, use the osqueryi command-line tool. For example:
osqueryi --snapshot /path/to/snapshot
Restoring a Snapshot
To restore a snapshot, use the osqueryi command-line tool. For example:
osqueryi --restore /path/to/snapshot
