Data Sources
A data source is any product that feeds data into the Lumin Exposure View interface. By default, Lumin Exposure View automatically ingests data from any Tenable product for which you have a license. On the Data Sources tab, you can view details for each data source.
To view the Data Sources page:
-
Access the Settings menu.
-
Click Data Sources.
The Data Sources page appears.
On the Data Sources page, you can view the following information:
| Column | Description |
|---|---|
| Data Source | The product feeding data into the Lumin Exposure View interface. |
| Description | A description of the data source. |
| Category | The category to which the data source belongs. For more information, see Lumin Exposure View Metrics. |
Data Timing
Data within Lumin Exposure View refreshes on the following cadence:
-
Asset Data — Asset information is updated every time the asset is seen as part of a scan.
-
Tag Application — When a tag is first created, it can take several hours to assign the tag to the appropriate asset, depending on the number of assets and the tag's rules.
-
Tag Reevaluation — Every 12 hours, Lumin Exposure View automatically reevaluates tags to ensure they apply to newly discovered assets, and are removed from any inactive assets.
