EFS access points should enforce a user identity

This control checks whether AWS EFS access points are configured to enforce a user identity. This control fails if a POSIX user identity is not defined while creating the EFS access point.

How to fix

Attribute posix_user[0].uid of aws_efs_access_point must be non-empty.

Implementation options

Choose the option that matches how you manage Terraform. All options satisfy this control.

Option 1: Terraform AWS provider resources

If you manage resources directly, configure the relevant Terraform AWS provider resources to meet this control. See docs for the resources involved: aws_efs_access_point.

resource "aws_efs_access_point" "this" {
  file_system_id = "fs-abc123"

  posix_user {
    gid = 1000
    uid = 1000
  }
}
Which option should I choose?
  • Compliance.tf module (recommended): controls enforced by default and mapped to frameworks.
  • Open source module (terraform-aws-modules): compatible by design with compliance.tf. Same variable names for an easy, low-change migration path when you are ready.
  • Terraform AWS provider resources: manage Terraform resources directly.
