# port\_8443\_scanning\_internal

**Explanation**

This NDM was created by the Netography Threat Research team to detect unauthorized scanning activities on port 8443 inside the network.

**What to Look For**

When reviewing the results of this NDM event, look for any Source IPs that are not authorized for scanning activities on port 8443. These IPs should be investigated immediately to determine if there is any malicious intent behind the scanning activity. Remediation steps should be taken to block or restrict access to these IPs to prevent further scanning activities on the network.

## 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/port_8443_scanning_internal.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.
