To schedule this query, we add it into the schedule in our nf: '.format( | type | user | tty | host | time | pid | The nf controls these settings, including other daemon ( osqueryd) behaviors.įor example, the following query output can display all currently logged in osquery> SELECT * FROM logged_in_users WHERE type ='user' Osquery periodically reports data by querying specific tables and sending results in JSON format to the configured logger_plugin(s), which can be the filesystem, a TLS endpoint, or AWS. Osquery can be installed on Mac, Linux, or Windows. To install osquery, follow the instructions here. Local Configuration for osquery on Windows I pretty commonly get asked by folks for a generic Windows configuration for osquery, as the example configuration pack in the osquery repository favors posix systems a bit ( Something we’re hoping to make better ). This tutorial was last updated in February 2021. Panther also comes with pre-installed rules based on default query packs, which provides value for most osquery deployments.įor the purpose of this tutorial, we will assume an osquery installation on Ubuntu 18.04. In this tutorial, we will walk through how to configure osquery with Panther to create an end-to-end security alerting pipeline to send logs for analysis and then notifying your team on a specific activity. Security teams use osquery to track activity in their fleet such as user logins, installed programs, running processes, network connections, or system log collection. Osquery is a powerful, host-based application that exposes the operating system as a set of SQLite tables. Onboard and analyze Osquery logs with Panther Overview
