# Target Variant

Every Custom Scan step needs a [target and baseline](/security-testing-orchestration/new-to-sto/key-concepts/targets-and-baselines.md).

* [Target name](#target-name)
* [Target variant](#target-variant)

**Target name**

**Key**

```yaml
target_name
```

**Value**

A user-defined label for the code repository, container, application, or configuration to scan. Specify a unique, descriptive name. This makes it much easier to navigate your scan results in the STO UI.

**Target variant**

**Key**

```yaml
target_variant
```

**Value**

A [user-defined label](/security-testing-orchestration/new-to-sto/key-concepts/targets-and-baselines.md) for the branch, tag, or other target variant to scan.
