# Select Detection Rules in Nightfall for JIRA
Now you must create the detection rules that define the types of sensitive data that Nightfall scans and capture any violations.
A detection rule can be one detector or a combination of detectors and confidence levels/findings that will define a violation or finding and record it. The following table defines the rules for detectors.
To learn more about Detection Rules and how to set them up, refer [Detection Rules](https://app.nightfall.ai/detection-engine/detection-rules).
Nightfall recommends configuring a simple detection rule to start as shown below.
| Detector | Minimum Confidence | Minimum Count |
| ------------------------- | ------------------ | ------------- |
| Credit Card Number | Likely | 1 |
| US Social Security Number | Likely | 1 |
| API Key | Likely | 1 |
To select detection rules, select a detection rule from the list of rules that are displayed and then select one of the following options.
* **All Detection Rules**: Select this option to include all the detection rules in the policy.
* **Selected Detection Rules**: Select this option to include only that detection rule in the policy that you selected above.
* **Unselected Detection Rules**: Select this option to include all the other detection rules in the policy, that you did not select above.
Click **Next**.

## 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://help.nightfall.ai/jira/policies/detection_rules.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.
