# rdp\_scanning\_outside\_to\_inside

**Explanation**

This NDM was created by the Netography Threat Research team to detect Microsoft RDP scanning. It triggers when an external IP address attempts to scan the network for open RDP ports in an attempt to gain access to internal systems.

**What to Look For**

When this event is triggered, examine the IP address of the attacker and the targeted IP addresses to determine if any unauthorized RDP connections were made. It is recommended to immediately block the external IP address and review internal security policies and configurations to prevent future 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/rdp_scanning_outside_to_inside.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.
