What is osquery?
osquery is an open-source endpoint visibility tool that uses SQL to collect and analyze data from operating systems, providing a unified interface for querying and managing endpoint data. It allows administrators to write SQL queries to explore operating system data, providing a powerful tool for IT, security, and compliance teams. osquery is widely used for its ability to provide real-time visibility into endpoint activity, enabling teams to detect and respond to security threats more effectively.

While these tools offer similar functionality, osquery’s use of SQL and its flexible architecture set it apart from other solutions.
osquery Snapshot and Restore Workflow
Overview
The osquery snapshot and restore workflow allows administrators to capture and restore endpoint data, providing a way to recover from system failures or security incidents.
Step-by-Step Guide
Follow these steps to use the osquery snapshot and restore workflow:
- Create a snapshot of the endpoint data using the osquery snapshot command.
- Store the snapshot in a secure location, such as a network share or cloud storage.
- In the event of a system failure or security incident, restore the endpoint data from the snapshot using the osquery restore command.
