The process table also includes a column called on_disk which might help identify suspicious processes spawned from memory. You can use query recursion to iterate through parent processes to identify a given processes execution path. WITH RECURSIVE rc(pid, parent, name) AS ( SELECT pid, parent, name FROM processes WHERE pid = 55334 UNION ALL SELECT p.pid, p.parent, p.name FROM processes AS p, rc WHERE p.pid = rc.parent AND p.pid != 0 ) SELECT pid, parent, name FROM rc LIMIT 20 However, I want to cover a few neat tricks taking advantage of the SQLite engine used by OSquery. We published a previous post on this which covers collecting process information from the processes table and the corresponding application hashes as well as event information from process_events table. SELECT name, version, build, platform FROM os_version Processes and process events This is useful for identifying systems that may not be running the latest OS release. The os_version table provides operating system information and the current patch level. SELECT uuid, hardware_serial, hostname, cpu_subtype, cpu_brand, physical_memory, hardware_vendor, hardware_model FROM system_info A serial number in the case of Apple or Dell service tag. The hardware_serial column will also provide the manufactures hardware identifier. The system_info table also provides the system UUID to help uniquely identify the asset within your IT estate. The system_info table will provide basic system information around the CPU and available memory. The following system queries will run across all platforms. Osquery provides access to several tables relating to various aspects of system information. Install Osquery on the monitored CentOS 8 endpoint.Īdd this content block to the Osquery configuration file /etc/osquery/ captured from systems using Osquery System information.ConfigurationĬonfigure your environment as follows to test the POC. More information about using Osquery with Wazuh can be found in the Osquery section of our documentation. This integration can be helpful for telemetry and threat hinging. Wazuh agent can be integrated with Osquery, making it easy to capture additional information from the endpoint. Monitor your corporate Windows or macOS clients the same way you monitor your production Linux servers. This has the distinct advantage of allowing you to be able to use one platform for monitoring complex operating system state across your entire infrastructure. Even though osquery takes advantage of very low-level operating system APIs, you can build and use osquery on Windows, macOS, Ubuntu, CentOS and other popular enterprise Linux distributions. With the power of a complete SQL language and dozens of useful tables built-in, osqueryi is an invaluable tool when performing incident response, diagnosing a systems operations problem, troubleshooting a performance issue, etc. The interactive query console, osqueryi, gives you a SQL interface to try out new queries and explore your operating system. osqueryd‘s logging can integrate into your internal log aggregation pipeline, regardless of your technology stack, via a robust plugin architecture. You can use this to maintain insight into the security, performance, configuration, and state of your entire infrastructure. The daemon takes care of aggregating the query results over time and generates logs which indicate state changes in your infrastructure. The high-performance and low-footprint distributed host monitoring daemon, osqueryd, allows you to schedule queries to be executed across your entire infrastructure. With osquery, SQL tables represent abstract concepts such as running processes, loaded kernel modules, open network connections, browser plugins, hardware events or file hashes. This allows you to write SQL queries to explore operating system data. Osquery exposes an operating system as a high-performance relational database. The tools make low-level operating system analytics and monitoring both performant and intuitive. Osquery is an operating system instrumentation framework for Windows, OS X (macOS), Linux, and FreeBSD. This post is about “Osquery integration with Wazuh” What is osquery?
