## Impact

This rule identifies Azure Storage accounts not configured with SAS expiration policy.

A Shared Access Signature (SAS) expiration policy specifies a recommended interval over which the SAS is valid. SAS expiration policies apply to a service SAS or an account SAS. When a user generates service SAS or an account SAS with a validity interval that is larger than the recommended interval, they'll see a warning. If Azure Storage logging with Azure Monitor is enabled, then an entry is written to the Azure Storage logs. It is recommended that you limit the interval for a SAS in case it is compromised.

## How to Fix

*Resource:* azurerm\_storage\_account

* *Arguments:* shared\_access\_key\_enabled, sas\_policy.expiration\_period

To mitigate this issue, implement one of the following options:

* Set the `shared_access_key_enabled` attribute in the `azurerm_storage_account` resource to 'false'
* Configure a `sas_policy` with a defined `expiration_period` if the `shared_access_key_enabled` attribute is set to 'true'

## Example: \[source,go]

resource "azurerm\_storage\_account" "example" { ... shared\_access\_key\_enabled = true

* sas\_policy {
* expiration\_period = "01.12:00:00"
* } }

## 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://cortex-docs.paloaltonetworks.com/appsec-rules/iac-security/iam/appsec2-azure-41.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.
