Ensure IAM password policy prevents password reuse

This control checks whether the number of passwords to remember is set to 24. The control fails if the value is not 24. IAM password policies can prevent the reuse of a given password by the same user.

How to fix

Attribute password_reuse_prevention of aws_iam_account_password_policy 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_iam_account_password_policy.

resource "aws_iam_account_password_policy" "this" {
  minimum_password_length = 14
}
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.
