# Security

{% hint style="info" %}
This page was generated from content adapted from the [AWS Developer Guide](https://github.com/awsdocs/aws-transfer-user-guide.git)

## Working with security policies

* **Note**\
  We support TLS 1.2.
* **Note**\
  `TransferSecurityPolicy-2020-06` is the default security policy attached to your server when creating a server using the console. `TransferSecurityPolicy-2018-11` is the default security policy attached to your server when creating a server using the API or CLI.
* **Note**\
  The FIPS service endpoint and TransferSecurityPolicy-FIPS-2020-06 security policy is only available in some AWS Regions. For more information, see [AWS Transfer Family endpoints and quotas](https://docs.aws.amazon.com/general/latest/gr/transfer-service.html) in the *AWS General Reference*.

## Cross-service confused deputy prevention

* **Note**\
  In the following examples, replace each *user input placeholder* with your own information.
* **Note**\
  In our examples, we use both `ArnLike` and `ArnEquals`. They are functionally identical, and therefore you may use either when you construct your policies. Transfer Family documentation uses `ArnLike` when the condition contains a wildcard character, and `ArnEquals` to indicate an exact match condition.
* **Note**\
  The following examples can be used in both logging and invocation roles.

## 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://awsnotes.dendron.so/migration-and-transfer/aws-transfer-family/common/security.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.
