# There are not only GCP-managed service account keys for each service account misconfiguration detect

## Impact

Anyone who has access to the keys will be able to access resources through the service account. GCP-managed keys are used by Cloud Platform services such as App Engine and Compute Engine. These keys cannot be downloaded.

Google will keep the keys and automatically rotate them on an approximately weekly basis. User-managed keys are created, downloadable, and managed by users. They expire 10 years from creation.

For user-managed keys, the user has to take ownership of key management activities which include:

* Key storage
* Key distribution
* Key revocation
* Key rotation
* Protecting the keys from unauthorized users
* Key recovery Even with key owner precautions, keys can be easily leaked by common development malpractices like checking keys into the source code or leaving them in the Downloads directory, or accidentally leaving them on support blogs/channels.

We recommended you prevent user-managed service account keys.

## How to Fix

*Resource:* google\_service\_account, google\_service\_account\_key

* *Arguments:* service\_account\_id \[source,go]

***

{ "resource "google\_service\_account" "account\_ok" { account\_id = "dev-foo-account" }

resource "google\_service\_account\_key" "ok\_key" { service\_account\_id = google\_service\_account.account\_ok.name }

## ", }

## 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-gcp-3.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.
