# outbound\_smb\_traffic

**Explanation**

This Netography Fusion Portal security event is triggered when outbound Windows Networking traffic is detected (including DCE-RPC, Netbios, or SMB).

**What to Look For**

When well tuned, this event can detect unauthorized Windows Networking activity, which may be indicative of data exfiltration or exploitation of vulnerabilities. Often, networks interact with cloud hosted Active Directory servers. Discards should be crafted for these known, authorized destination addresses so that unauthorized activity can be detected.

## 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/misconfiguration/outbound_smb_traffic.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.
