# censys\_scanning

**Explanation**

The censys\_scanning NDM is designed to detect any activity on your network that is related to Censys scanning.

**What to Look For**

If the censys\_scanning NDM is triggered, you should examine network configurations of devices like the firewall to ensure that you want to allow Censys to scan your network. Additionally, examine endpoint logs to identify any anomalies or security events that may have been caused by the scanning activity. To remediate the issue, you may need to block traffic from the identified IP addresses or take additional security measures to protect your network from potential attacks.

## 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.fusion.vectra.ai/detection-models/library/reconnaissance/censys_scanning.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.
