Cb Defense Syslog Connector 1.2.3 Released

Posted on June 27, 2017

The Carbon Black Developer Network is proud to announce the first public release of our syslog connector for Cb Defense. This connector allows you to forward alert notifications from your Cb Defense cloud instance into local, on-premise SIEM systems that accept industry standard syslog notifications. By default, it will generate pipe-delimited syslog messages containing the key metadata associated with any alert identified by the Cb Defense streaming prevention system.

The syslog connector will aggregate data from one or more Cb Defense organizations into a single syslog stream. The connector can be configured to use UDP, TCP, or encrypted (TCP over TLS) syslog protocols.

This connector is distributed as a binary RPM package compatible with any Red Hat or CentOS Linux distribution, CentOS/RHEL 6.x and above, running on a 64-bit Intel platform.

Installation

  1. Install the software. As root on your Carbon Black or other RPM based 64-bit Linux distribution server:

    cd /etc/yum.repos.d
    
    curl -O https://opensource.carbonblack.com/release/x86_64/CbOpenSource.repo
    
    yum install python-cb-defense-syslog
    
  2. Copy the example config file:

    cd /etc/cb/integrations/cb-defense-syslog
    
    cp cb-defense-syslog.conf.example cb-defense-syslog.conf
    
  3. Modify the config file /etc/cb/integrations/cb-defense-syslog/cb-defense-syslog.conf as needed

  4. Test the new connector. As root, execute:

    /usr/share/cb/integrations/cb-defense-syslog/cb-defense-syslog --config-file /etc/cb/integrations/cb-defense-syslog/cb-defense-syslog.conf --log-file /var/log/cb/integrations/cb-defense-syslog/cb-defense-syslog.log
    

    Then:

    cat /var/log/cb/integrations/cb-defense-syslog/cb-defense-syslog.log
    

    A successful run will look like:

  5. Start the connector by enabling it in cron. Uncomment the Cb Defense Connector (remove the beginning # from the last line) in /etc/cron.d/cb-defense-syslog. By default, the connector will run once per hour.
