If you are a sysadmin, developer, security researcher then this course is for you. It is a beginners course and no prior knowledge is required, not even about SQL. In this course you will learn how to use OSQuery to find information about your computers and servers. No privilege escalation is involved in using the OSQuery command line tool. However, these tools often require particular privilege to run (typically root) and have a narrow scope. It does this by collecting information from the operating system and making it available to clients (the osquery client, shipped as part of osqueryd), which can then be queried using a SQL-like query language.Ī lot of command-line tools such as ps, lsof, netstat or ss are available on every Linux distribution and allow you to query the operating system. Here are some of the API calls we used from D-Bus to extract the. D-Bus can be used to query things other than systemd. Meanwhile, D-Bus does use CMake, so it was simpler to integrate with osquery. It is a project that aims to make operating systems more transparent. Now, systemd does have its own bus library, sd-bus, but we still prefer D-Bus because: osquery uses CMake as its build system and systemd does not. ![]() Controls (Critical Security Controls for Effective Cyber Defense 2015) and. Get comprehensive, customizable data from all your devices and operating systems. By aggregating the individual data sources into a graph database based on a. ![]() This provides the flexibility that is unique to SQL-based interfaces and allows users to define a flexible query workflow. Lightweight telemetry platform for servers and workstations. A query may consist of individual or aggregated components that are composed together with AND / OR operators to form a complete query. Some sources of information include parts of the /proc file system, API calls to container daemons, reading logs or status files on disk, and event streams coming from the Linux audit frame. This allows complex queries to be constructed within a familiar environment that is both robust and secure. Inside osquery, theres typically a 1:1 correspondence between a source of information and the SQL table you can use to browse or search this information. They can also provide rich data for implementing supporting controls for compliance standards such as PCI, SOC2, and FedRAMP. These advanced capabilities provide a flexible and reliable source of data for auditing and implementing benchmarks such as CIS. The osquery toolset provides a SQL-based interface for querying operating system data. Using parsing lens (e.g., augeas), one can parse various configuration files. osquery supports multiple platforms including Windows, Linux and macOS. It is often used to collect information for security forensics, application performance management and compliance auditing. ![]() Osquery is an operating system instrumentation framework for collecting information from operating systems, hypervisors and applications.
