Integrating Microsoft Exchange Server and NXLog

Before you configure Microsoft Exchange Server to send logs to Sheriff CSM through NXLog, you must have the IP Address of the Sheriff CSM Sensor (Deputy).

Configure NXLog on Windows

To send log data through NXLog to Sheriff CSM

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 AT&T Cybersecurity.

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 Sheriff CSM Sensor IP address.

   1. Locate the following line:

      define OUTPUT_DESTINATION_ADDRESS <Sheriff-CSM-Sensor-IP>

   2. Replace <Sheriff-CSM-Sensor-IP> with the IP address of the Sheriff CSM All-in-One or Sheriff CSM Sensor that will receive the Windows events.

5. Uncomment the section between EXCHANGE-NXLOG and /EXCHANGE-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. Verify the file path defined in the section. Depending on the version of your Exchange Server, you may need to update the path to your Exchange Server logs.

7. Save the file.

8. Start or restart the NXLog service.
