Overview

You can use the Information Security Analytics (ISA) Manager to build a lookup table (LUT) in the platform.  Building a lookup table describes the process of indicating the JSON share where the lookup table is located, and specifying the Key Field and Header Fields in your lookup table.

Once the lookup table is built there are a number of different possible applications.  For example, you can apply the LUT to compare two sets of records and then create new records based on the results.

1. From the Treat Analytics Dashboard, click on Data Sources (top right).
2. Click on Add New Source.

About Testing

If the source has been configured properly testing with return test results, and you will be able to move forward with Publishing the new source.  Otherwise, a failure message is generated which can be used for troubleshooting (currently it only says FAIL).  You can always Save your source and come back to fix any testing errors later.
