![]() Return process count, name for the top 10 most active processes Select pid, name, uid, resident_size from processes order by resident_size desc limit 10 osquery at a glance Query for top 10 largest processes by resident memory size ![]() We’ll talk about some more of these below. For example: if you suspect a malicious process is running on a system, you can query for the process by name or even a filename it has open. From a security perspective, it can be used to query your endpoints to detect, investigate, and proactively hunt for various types of threats. Osquery is a flexible tool and can be used for a variety of use cases to troubleshoot performance and operational issues. Osquery allows you to craft your system queries using SQL statements, making it easy to use by security engineers that are already familiar with SQL. Osquery is an open source tool created by Facebook for querying various information about the state of your machines. There’s a lot of open source information on osquery.Last updated at Wed, 21:29:25 GMT What is osquery? Surprising there’s a nice starting point over at the Hortonworks Perfect fit for ingesting into a Hadoop environment, and not I briefly toyed with the idea that this would be a The local setup obviously does not scale beyond your ownĬomputer. Priority.A couple of things that I would have liked to see was support for TheĬlosed in 2018 and Android and iOS is low Platform support for other than Windows, MacOS andįreeBSD are issues left for exploration and needs porting. Of osquery and also had a compact view on a lab-setupĭemonstrating centralised logging, to Kolide, using the tls API of Through this article we’ve reviewed some of the basic capabilities SELECT hostname AS hostname FROM system_info ĭistributed_tls_read_endpoint: /api/v1/osquery/distributed/readĭistributed_tls_write_endpoint: /api/v1/osquery/distributed/write SELECT uuid AS host_uuid FROM system_info The config monitors changes in files under /etcĪnd a test directory at /var/tmp/filetest. Which I wasn’t able to get working by the patching curl Setup also involves setting up the osquery File Integrity The options.yaml I used for testing was the following. Managing the Kolide Configurationįor this part I found what worked best was using the Kolide CLIĬlient. To make the client persistent on macOS, use the following Local instance, based on a local configuration file: sudo osqueryi -disable_events=false -config_path=/etc/osquery/nf -config_path=/etc/osquery/nf Osquery also has an interactive mode if you would like to test the usr/local/bin/osqueryd -disable_events=false -flagfile=/private/var/osquery/osquery.flags Packaging, which is detailed in the osqueryĭocs. At this point you should start thinking about You can start the osquery daemon on the client by using theįollowing command. distributed_tls_write_endpoint=/api/v1/osquery/distributed/write distributed_tls_read_endpoint=/api/v1/osquery/distributed/read config_tls_endpoint=/api/v1/osquery/config enroll_tls_endpoint=/api/v1/osquery/enroll tls_server_certs=/etc/osquery/kolide.crt One the client uses to apply the centralised tls logging method, Make the API-token (enrollment secret) persistent at theĮnd-point: export > /etc/osquery/cretĭefine flags file in /private/var/osquery/osquery.flags. Get enrollment secret and certificate from the Kolide UI at build/fleet serve -auth_jwt_key=3zqHl2cPa0tMmaCa9vPSEq6dcwN7oLbP You are now ready to boot up the web UI and API server. There’s only two things that you need setup for the rest of thisĪrticle if you are on macOS, which can both be easily installedĪlso you need to configure your Go-path, which can basically be: echo "export GOPATH=$HOME/go" > ~/.bash_profileįleet: mkdir -p $GOPATH/src//kolide The next section shows you how to quickly get a lab environment up and running. So that was a couple of links to get you started. Doug Wilson’s excellent presentation on FIRST 2018.Posts about osquery that you should review before moving on:ĭoug Wilsons presentation during FIRST 2018 That is also some of what separates it from its Osquery is cross-platform, and now supports: Linux, FreeBSD, The briefs that’s online several major institutions, includingįacebook, now uses osquery in service networks. Since 2014 osquery has been open sourced and now has a largeĬommunity developing about every aspect of the tool. On the other hand, events can be streamed as wellĮxample of the hardware_events table when plugging in and then detaching a Yubikey In practical terms this means that queriesĪre distributed. osquery can even parse native sqlite-databases, Near-infinite amount of available data, which is perfect to a The agent runs, to a SQL-based interface. With osquery data is abstracted, in the operating system in which Maintaining real-time insight into the current state of your infrastructure
