# Updating an AWS service account stack

> Learn how to update an AWS service account stacks to maintain permissions and regional infrastructure for CWPP scanning.

With the AWS service account integration, you can update existing **Permission** and **Region Stacks** to ensure your Plerion CWPP appliances continue to operate securely and efficiently across regions.

A **service account stack** may require updates over time due to changes in permissions, AWS regional support, or infrastructure improvements.\
There are two types of stacks that may need updates:

* **Permission Stack:** Grants Plerion access to the service account through IAM roles and policies.
* **Region Stacks:** Provisions the infrastructure required to run Plerion Service Account Appliances, including VPCs, subnets, security groups, and auto-scaling resources.
