This process involves mapping the severity levels from various scanners and sources to a common severity scale used within Unified Security Exposure Management. ## Severity mapping **Note:** Business rules run in the background to evaluate the priority for Qualys data and perform the corresponding mapping to the **Priority** field. Therefore, the business rule is responsible for handling the mapping of Qualys data.
| Field | Description |
|---|---|
| Normalised\_Severity | Calculates the severity values received from the scanner. |
| **Source\_severity** | - Data from the **severity\_score** table is mapped to the **source\_severity** table during the execution of the **Rapid7 Vulnerability Integration- API.** - Data from the **SEVERITY\_LEVEL** is mapped to the **source\_severity** table during the execution of the **Qualys Knowledge Base Integration**. - Data for **risk\_factor** table is mapped to **source\_severity** during the execution of the **Tenable.io Plugin Integration**. - Data for **riskFactor** table is mapped to **source\_severity** during the execution of the **Tenable.io Plugin Integration**. - Data from **severity** table is mapped to **source\_severity** during the execution of the **Microsoft TVM Vulnerability\(CVE\) Integration**. |
