What is osquery?

osquery is an open-source endpoint visibility tool that allows administrators to query and manage their infrastructure using SQL. It provides a powerful way to collect and analyze data from endpoints, enabling teams to identify and respond to security threats, monitor system performance, and enforce compliance. With osquery, organizations can gain real-time visibility into their infrastructure, making it easier to detect and respond to potential security issues.

Key Features

Endpoint Visibility

osquery provides a comprehensive view of endpoint activity, including process creation, network connections, and file system modifications. This allows administrators to quickly identify potential security threats and take corrective action.

SQL-based Querying

osquery uses a SQL-based query language, making it easy for administrators to write custom queries and analyze data. This allows teams to create tailored queries to meet specific security and compliance requirements.

Scalability and Performance

osquery is designed to scale to large environments, making it an ideal solution for organizations with thousands of endpoints. Its high-performance architecture ensures that queries are executed quickly, even in large environments.

osquery Snapshot and Restore Workflow

Creating a Snapshot

A snapshot is a point-in-time representation of your endpoint’s state. To create a snapshot, use the following command:

osqueryctl snapshot --interval 3600

This command creates a snapshot every hour.

Restoring from a Snapshot

To restore from a snapshot, use the following command:

osqueryctl restore --snapshot-id <snapshot_id>

Replace <snapshot_id> with the ID of the snapshot you want to restore from.
