## Impact

This rule detects whether an AWS Transfer Server is not configured to use the latest security policy, defined as one that is no older than 24 months. Security policies in AWS Transfer specify the encryption algorithms and protocols used during file transfers. Using outdated policies can be risky, as they may rely on deprecated or weaker encryption methods vulnerable to security threats. By ensuring that the latest security policy is applied, organizations can maintain strong encryption standards, enhance data protection, and adhere to best practices for secure communication, safeguarding sensitive data from unauthorized access and potential breaches.

## How to Fix

*Resource:* aws\_transfer\_server

* *Arguments:* security\_policy\_name

Set your AWS Transfer Server to use the latest security policy to secure data transfers. Associate each `aws_transfer_server` resource with the most recent `security_policy_name` to maintain high security standards.

## In this example, the security policy for an AWS Transfer Server is updated to the latest version using Terraform. \[source,go]

resource "aws\_transfer\_server" "example" { ...

* security\_policy\_name = "TransferSecurityPolicy-2024-01" ... }

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 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/public-exposure/appsec-aws-380.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.
