Other Notes

If you are using email subscriptions, they must be created outside of terraform because of the validation required. This is a design decision made Terraform developers that can't easily be worked around. See the Unsupported protocol list here: https://www.terraform.io/docs/providers/aws/r/sns_topic_subscription.html

TODO

• Add support for notification subscriptions
• Consider creating a control sub-module that would define datasource,create the metric and the alarm (e.g. module "cis_control_3_1")
• As I expand the Controls cloudtrail_log_group should optionally be created in module
