# teamviewer\_usage

**Explanation**

This NDM looks for the usage of the TeamViewer software, which may pose a security risk for organizations. The NDM is triggered when the software is detected on a network or endpoint, and analyzes the activity associated with it.

**What to Look For**

To examine the results of the teamviewer\_usage NDM event, look for instances of TeamViewer software on your network or endpoints. Review any associated activity logs for suspicious or unauthorized access attempts. Consider restricting or monitoring the use of TeamViewer to reduce the risk of unauthorized access and data breaches.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## 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/operational-governance/teamviewer_usage.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.
