Integrating ObserveIT Logs

The USM Appliance ObserveIT plugin leverages the integration support that ObserveIT provides for the HP ArcSight SIEM monitoring software. Follow the ObserveIT documentation to configure the SIEM Log Integration.

Important: Follow the steps closely and keep all the default values even though they contain the word "ArcSight". The NXLog configuration file that you download from AlienVault has been specified to parse logs in the default location.

Before you configure the integration, you must have the IP Address of the USM Appliance Sensor.

Configure NXLog on Windows

To send log data through NXLog to USM Appliance

  1. If not done already, download nxlog.conf, and then place it in the conf directory of your NXLog installation. Depending on which version you use, the directory can be C:\Program Files (x86)\nxlog\conf for the 32-bit version or C:\Program Files\nxlog\conf for the 64-bit version.

    Note: This step overwrites the default nxlog.conf file. You may want to back up the original copy before placing the one provided by AlienVault.

  2. Open the nxlog.conf file in a text editor.
  3. Update the ROOT path of your NXLog installation.

    1. Locate the following lines

      #define ROOT C:\Program Files\nxlog

      #define ROOT C:\Program Files (x86)\nxlog

    2. Uncomment the path that matches the NXLog installation on your Windows machine.
  4. Enter the USM Appliance Sensor IP address.

    1. Locate the following line

      define OUTPUT_DESTINATION_ADDRESS <USM-Appliance-Sensor-IP>

    2. Replace <USM-Appliance-Sensor-IP> with the IP address of the USM Appliance All-in-One or USM Appliance Sensor that will receive the Windows events.
  5. Uncomment the section between OBSERVEIT-NXLOG and /OBSERVEIT-NXLOG.

    Important: Only remove the first # symbol in each line when uncommenting the sections. The remaining # symbol indicates that the line is either a comment or optional.

  6. Save the file.
  7. Start or restart the NXLog service.
