# BigID Integration Discovered Resources

## Overview

The BigID integration augments **table** and **column** resources with BigID classification and sensitivity metadata. BigID does not create new resource types; it adds BigID-specific indexed properties to warehouse tables and columns that already exist in Euno.

For each structured BigID catalog row that passes filters and maps to a supported warehouse (**BigQuery**, **Snowflake**, or **Databricks**), Euno emits a **table** observation with `bigid_`\* properties—even when BigID has no attributes or sensitivity tags for that table (properties may be empty lists or null). **Column** observations are emitted only when BigID reports attributes and/or column-level sensitivity tags for that column.

The following properties are written when those observations are materialized.

## Table – BigID Properties

For each observed table, the integration sets these properties on the table resource (values may be empty or null when BigID provides no matching metadata):

| Property           | Value                                                                                                                                                                                                                                                 |
| ------------------ | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| bigid\_attributes  | Distinct BigID attribute names assigned to the table and its columns (for example, `Email`, `SSN`, `businessTerm.CustomerName`). Values pass the source's attribute pattern and confidence threshold filters. An empty list when no attributes match. |
| bigid\_sensitivity | The highest BigID sensitivity label on the table or any of its columns, stored as the **raw BigID value** (for example, `High`, `Restricted`, `Confidential`).                                                                                        |
| bigid\_categories  | Attribute categories from BigID metadata (for example, `PII`, `PHI`, `PCI`, `Personal Data`). Empty or absent if no categories are present.                                                                                                           |

### Sensitivity display mapping

BigID sensitivity labels are tenant-configurable. The stored `bigid_sensitivity` value is always the raw BigID label; the Euno UI maps common BigID values onto its shared seven-level display scale (badges and sidepane) as follows:

| BigID label (examples)  | Euno display name |
| ----------------------- | ----------------- |
| Restricted, Top Secret  | Top Secret        |
| Critical, High          | Very Sensitive    |
| Confidential            | Confidential      |
| Medium                  | Sensitive         |
| Internal, Internal Use  | Internal          |
| Low, Public             | Public            |
| Missing or unrecognized | Unclassified      |

## Column – BigID Properties

When a column has BigID attribute or sensitivity metadata, the BigID integration adds these indexed properties to the column resource:

| Property           | Value                                                                                                                                                                                                                       |
| ------------------ | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| bigid\_attributes  | List of BigID attribute names assigned to the column (for example, classification labels or data categories).                                                                                                               |
| bigid\_sensitivity | The highest BigID sensitivity label assigned directly to the column, stored as the **raw BigID value** (for example, `High` or `Restricted`). Null when BigID currently reports no sensitivity tag for the observed column. |

Columns do not have `bigid_categories`; attribute categories apply at the table resource.

## Relationships

The BigID integration does not create new relationships. It enriches existing table and column resources that match warehouse URIs in Euno.

## Usage in EQL

You can filter and search by BigID properties in Euno's search and EQL:

**Examples**:

```
# Tables with at least one BigID attribute
bigid_attributes is not null

# Tables whose attribute list includes a specific label
'classifier.Email' IN bigid_attributes

# Case-insensitive attribute match
i'email' IN bigid_attributes

# Tables at a specific BigID sensitivity (raw BigID label, as configured in your BigID tenant)
bigid_sensitivity = 'High'

# Columns at a specific BigID sensitivity
bigid_sensitivity = 'Restricted' AND type = 'column'

# Tables in a BigID attribute category
'PII' IN bigid_categories

# Columns with BigID attribute metadata (column observations are only emitted when metadata exists)
bigid_attributes is not null AND type = 'column'
```

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.euno.ai/sources/data-security/bigid-integration/bigid-integration-discovered-resources.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
