Description

Abstract

I want to add support to identify aws_ec2_client_vpn_endpoint resources that do not set client_login_banner_options arguments.

Motivation

When supplying security scan results to clients, we need the ability to show VPN client banner options are properly set in accordance with NIST CPRT SP 800-53 Release 5.1.1 AC-08 control.

Proposal

I'm considering adding the following code:
