The osquery has a vibrant community of users and developers, most of which hang out on Slack. If you’ve found this article interesting, I encourage you to check out the Launcher source.
Launcher implements config, logger and other pugins for osquery using gRPC and the Go kit toolkit to effectively manage osqueryd at scale for various environments. Once again, Go makes this process easy by allowing us to use build tags when writing platform specific plugins.Īt Kolide, we’ve been writing our own open source osqueryd extension called Launcher. For example, the journal and systemd APIs are not available on macOS or windows, so we have to compile our custom extensions in a different way for each platform.
KOLIDE OSQUERY HOW TO
In the article I’ve given an overview of osquery and how to use the Go plugin SDK to write your own custom extensions.īesides creating the plugins we also have to think about packaging, distribution and the platforms we’re running the osquery daemon on. To keep things simple, we’ll load configuration from a GitHub gist.īy now, you can probably guess what the API of the /kolide/osquery-go/plugin/config looks like. We’ll implement a plugin which configures the osquery process and schedules a list of schedules queries to run. Just like you can log results with a custom logger, you can load configuration through a custom plugin. Speaking of configuration, how are you configuring the osquery process? The recommended way is a configuration management tool like Chef, or a dedicated TLS server like Fleet, but maybe you’ve got custom requirements? Config plugins for osquery | 6308708 | rvice | nginx | :: | 443 | 25859 |īy configuring the query to run on a schedule, and using the logger plugin to aggregate the results centrally, we can begin to instrument our systems and create alerts. | start_time | service | name | address | port | pid | Osquery> SELECT process.start_time, systemd.name AS service, process.name, listening.address, listening.port, process.pid FROM processes AS process JOIN listening_ports AS listening ON (process.pid = listening.pid) JOIN systemd ON systemd.pid = process.pid and listening.port = 443 The /kolide/osquery-go/plugin/logger package exposes the following API which we need to implement. The go-systemd library from CoreOS has a convenient package we can use to write to journald. Go, having support for most APIs these days, is an ideal language for implementing a logger.įor the purpose of this tutorial, we’ll implement a systemd journal logger. With the Thrift bindings to osquery, you can write your own logger. But what if you already have a well established logging pipeline with the systemd journal, Splunk, fluentd or any number of proprietary logging systems. The kinesis plugin sends logs results to AWS, allowing advanced monitoring with applications like StreamAlert. The tls plugin sends all logs to a remote TLS server like Fleet. Commonly oquery users use aggregation tools like filebeat to send the result logs to a centralized log platform. By default, a filesystem plugin is used, which logs the results to a local file. When a scheduled query like SELECT name, version from deb_packages is executed, the osqueryd daemon will create a JSON log event with the results of the query. In this blog post, it’s my goal to show you how you can get started with osquery development using the osquery-go SDK.
KOLIDE OSQUERY FULL
Earlier this year our team at Kolide released a set of Go packages with idiomatic interfaces that allow anyone to use the full power of Go to extend osquery.

Osquery is a powerful tool, but it’s written in C++, so why are we talking about it in a GopherAcademy post? Osquery uses Thrift (a project similar to gRPC) to allow developers to extend osquery through a series of plugin types.
KOLIDE OSQUERY WINDOWS
With almost 200 tables available by default and support for macOS, Linux and Windows hosts, osquery is the tool of choice for many security and system administration teams.
KOLIDE OSQUERY PASSWORD
When the root password vulnerability became know a few weeks ago, the osquery community quickly crafted a query which would identify vulnerable macs in a fleet of devices. \tools\deployment\make_windows_package.ps1 -Type msi - ConfigFile C:\Path\To\nf -FlagFIle C:\Path\To\osquery.What if you could use SQL to query any aspect of your infrastructure? Osquery, an open source instrumentation tool released by the Facebook security team allows you to do just that.įor example, SELECT network_name, last_connected, captive_portal FROM wifi_networks WHERE captive_portal=1 will show all captive portal WiFi networks that a laptop has connected to.Īnd SELECT * FROM processes WHERE on_disk = 0 will show any process that is running where the binary has been deleted from disk.
