# Enable new attack surface tests by default
When you first enable Attack Surface Testing, all existing attack surface tests with intrusiveness level 0 or level 1 are enabled by default. Moving forward, all new tests that are introduced, for all intrusiveness levels, are disabled by default. To configure Cortex Xpanse to automatically enable new attack surface tests and to specify the intrusiveness level of those default tests, perform the steps below. After the initial set-up, you can update this set of defaults anytime.
1. Navigate to **Settings** → **Configurations** → **Vulnerability Testing Configuration**.
2. In the **New Vulnerability Tests section**, select the intrusiveness level for the new tests you want to be enabled by default moving forward. The intrusiveness level you select will include the tests for the levels below it. For example, if you select Level 2, then new level 0, level 1, and level 2 tests will be enabled moving forward.

## 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://cortex-docs.paloaltonetworks.com/cortex-xpanse/attack-surface-testing/enable-new-attack-surface-tests-by-default.md?ask=&goal=
```
`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.
