Integrating Osquery With Blumira’s Cloud SIEM

Note: Commands listed in this document are Linux flavor-agnostic and should work on all tested OSes, including Ubtunu, CentOS and RHEL.

There are two ways to send logs from Osquery to Blumira, manually or automatically (via a script). Do one of the following, depending on how you want to send logs:

  • For manual deployment, follow steps 1-5 in Section 1 below.
  • For automated deployment, skip to Section 2 below.

Section 1

1. Set Up Rsyslog For Blumira

Follow the steps in this document: https://www.blumira.com/integration/linux/

2. Install Osquery

Go to the following link and download the most recent version of Osquery for your respective OS:  https://osquery.io/downloads/ 

3. Download Osquery Config

Run the following commands: 

git clone https://github.com/palantir/osquery-configuration.git

sudo cp -av osquery-configuration/Classic/Servers/Linux/* /etc/osquery/
sudo chown -R root. /etc/osquery/

sudo systemctl enable osqueryd.service

sudo systemctl start osqueryd.service

4. Create Osquery Rsyslog Config File

Run the following command: 

sudo vim /etc/rsyslog.d/osquery.conf


sudo nano /etc/rsyslog.d/osquery.conf

Copy and paste the following code into the osquery.conf:

# Prep
$ModLoad imfile
$InputFilePollInterval 10
$PrivDropToGroup adm
$WorkDirectory /var/spool/rsyslog


# Apache Access File:
$InputFileName /var/log/osquery/osqueryd.results.log
$InputFileTag osqueryd:
$InputFileStateFile stat-osquery
$InputFileSeverity info
$InputFilePersistStateInterval 20000


# Tag, Forward to BLUNIX System Logger then Stop
if $programname == 'osqueryd' then stop

5. Ensure Rsyslog Can Read the File and then Restart

Run the following commands: 

sudo chown syslog. /var/log/osquery/osqueryd.results.log
sudo systemctl restart rsyslog.service

Section 2

Automated Deployment Option: Run OSquery Autodeploy Script

If you need to support larger deployments, Blumira has a script that will automate the process listed in Section 1.

Before you begin:

  1. Install git 
  2. Disable auditd 

After you’ve met the Section 2 prerequisites, follow the steps below:

1. Download the Config File From Github

To download, visit: https://github.com/Blumira/blumira-osquery-config

2. Run Commands

Run the command: >./osquery-deploy.sh -h

sudo osquery-deploy.sh -d [select OS: ubuntu|rhel|centos] -s <IP of Blumira Sensor>

For example: sudo osquery-deploy.sh -d ubuntu -s


On RedHat/Centos systems in AWS auditd is enabled, which will prevent osquery process monitoring.

To disable this, run the following commands:
sudo systemctl stop auditd.service
sudo systemctl disable auditd.service
sudo systemctl restart osqueryd.service
