## Impact

This rule ensures that MongoDB instances in Alibaba Cloud are deployed inside a VPC (Virtual Private Cloud). Deploying MongoDB inside a VPC provides network isolation and enhanced security, ensuring that the database is accessible only to resources within the same VPC and not exposed to the public internet.

Failing to deploy MongoDB inside a VPC can result in exposure to public internet traffic, increasing the risk of unauthorized access and potential data breaches.

## How to Fix

*Resource:* alicloud\_mongodb\_instance

* *Attribute:* network\_type

To mitigate this issue, ensure that the `network_type` attribute in the `alicloud_mongodb_instance` resource is set to `VPC`.

## Example: \[source,go]

resource "alicloud\_mongodb\_instance" "example" { ...

* network\_type = "VPC" }

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://cortex-docs.paloaltonetworks.com/appsec-rules/iac-security/networking/appsec-ali-41.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
