# port\_8443\_scanning\_outbound

**Explanation**

The port\_8443\_scanning\_outbound NDM detects outbound scans on port 8443 from the customer’s network.

**What to Look For**

To examine the results of the port\_8443\_scanning\_outbound NDM, check the network logs for outbound traffic on port 8443 from an internal source IP. Check the endpoint logs for any suspicious activity related to scanning or port 8443. This event indicates a potential security threat and should be investigated further to prevent any malicious activity.

## 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_outbound.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.
