FedRAMP Low Baseline Rev 4¶
The Federal Risk and Authorization Management Program (FedRAMP) Low Impact Baseline Revision 4 establishes security requirements for cloud services handling low-impact federal information. Managed by the U.S. General Services Administration (GSA), this baseline is derived from NIST SP 800-53 and requires implementation of 125 security controls. It applies to cloud service providers offering services to U.S. federal agencies for systems with low confidentiality, integrity, and availability requirements.

Enable/Disable Controls¶
You can customize the Terraform module for the desired compliance requirements by enabling/disabling individual controls.
Examples¶
S3 bucket module with FedRAMP Low Baseline Rev 4 compliance framework controls enabled, and a couple of controls disabled¶
module "..." {
source = "https://fedramplow.compliance.tf/terraform-aws-modules/s3-bucket/aws?disable=apigateway_stage_logging_enabled,backup_plan_min_retention_35_days"
