Operational Best Practices for CMMC Level 2
Conformance packs provide a general-purpose compliance framework designed to enable you to create security, operational or cost-optimization governance checks using managed or custom AWS Config rules and AWS Config remediation actions. Conformance Packs, as sample templates, are not designed to fully ensure compliance with a specific governance or compliance standard. You are responsible for making your own assessment of whether your use of the Services meets applicable legal and regulatory requirements.
The following provides a sample mapping between the Cybersecurity Maturity Model Certification (CMMC) Level 2 and AWS managed Config rules. Each Config rule applies to a specific AWS resource, and relates to one or more CMMC Level 2 controls. A CMMC Level 2 control can be related to multiple Config rules. Refer to the table below for more detail and guidance related to these mappings.
AWS Region: All AWS Regions where conformance packs are supported (Region support) except AWS GovCloud (US-East), AWS GovCloud (US-West), and Middle East (Bahrain)
| Control ID | Control Description | AWS Config Rule | Guidance |
|---|---|---|---|
| AC.1.001 | Limit information system access to authorized users, processes acting on behalf of authorized users, or devices (including other information systems). | The credentials are audited for authorized devices, users, and processes by ensuring IAM access keys are rotated as per organizational policy. Changing the access keys on a regular schedule is a security best practice. It shortens the period an access key is active and reduces the business impact if the keys are compromised. This rule requires an access key rotation value (Config Default: 90). The actual value should reflect your organization's policies. | |
| AC.1.001 | Limit information system access to authorized users, processes acting on behalf of authorized users, or devices (including other information systems). | Manage access to the AWS Cloud by ensuring DMS replication instances cannot be publicly accessed. DMS replication instances can contain sensitive information and access control is required for such accounts. | |
| AC.1.001 | Limit information system access to authorized users, processes acting on behalf of authorized users, or devices (including other information systems). | Manage access to the AWS Cloud by ensuring EBS snapshots are not publicly restorable. EBS volume snapshots can contain sensitive information and access control is required for such accounts. | |
| AC.1.001 | Limit information system access to authorized users, processes acting on behalf of authorized users, or devices (including other information systems). | Ensure the Instance Metadata Service Version 2 (IMDSv2) method is enabled to help protect access and control of Amazon Elastic Compute Cloud (Amazon EC2) instance metadata. The IMDSv2 method uses session-based controls. With IMDSv2, controls can be implemented to restrict changes to instance metadata. | |
| AC.1.001 | Limit information system access to authorized users, processes acting on behalf of authorized users, or devices (including other information systems). | Manage access to the AWS Cloud by ensuring Amazon Elastic Compute Cloud (Amazon EC2) instances cannot be publicly accessed. Amazon EC2 instances can contain sensitive information and access control is required for such accounts. | |
| AC.1.001 | Limit information system access to authorized users, processes acting on behalf of authorized users, or devices (including other information systems). | EC2 instance profiles pass an IAM role to an EC2 instance. Attaching an instance profile to your instances can assist with least privilege and permissions management. | |
| AC.1.001 | Limit information system access to authorized users, processes acting on behalf of authorized users, or devices (including other information systems). | Manage access to the AWS Cloud by ensuring Amazon OpenSearch Service (OpenSearch Service) Domains are within an Amazon Virtual Private Cloud (Amazon VPC). An OpenSearch Service domain within an Amazon VPC enables secure communication between OpenSearch Service and other services within the Amazon VPC without the need for an internet gateway, NAT device, or VPN connection. | |
| AC.1.001 | Limit information system access to authorized users, processes acting on behalf of authorized users, or devices (including other information systems). | The access permissions and authorizations can be managed and incorporated with the principles of least privilege and separation of duties, by enabling Kerberos for Amazon EMR clusters. In Kerberos, the services and the users that need to authenticate are known as principals. The principals exist within a Kerberos realm. Within the realm, a Kerberos server is known as the key distribution center (KDC). It provides a means for the principals to authenticate. The KDC authenticates by issuing tickets for authentication. The KDC maintains a database of the principals within its realm, their passwords, and other administrative information about each principal. | |
| AC.1.001 | Limit information system access to authorized users, processes acting on behalf of authorized users, or devices (including other information systems). | Manage access to the AWS Cloud by ensuring Amazon EMR cluster master nodes cannot be publicly accessed.

| AC.1.001 | Limit information system access to authorized users, processes acting on behalf of authorized users, or devices (including other information systems). | Enable this rule to restrict access to resources in the AWS Cloud. This rule ensures multi-factor authentication (MFA) is enabled for all users. MFA adds an extra layer of protection on top of sign-in credentials. Reduce the incidents of compromised accounts by requiring MFA for users. | |
| AC.1.001 | Limit information system access to authorized users, processes acting on behalf of authorized users, or devices (including other information systems). | This rule ensures AWS Identity and Access Management (IAM) policies are attached only to groups or roles to control access to systems and assets. Assigning privileges at the group or the role level helps to reduce opportunity for an identity to receive or retain excessive privileges. | |
| AC.1.001 | Limit information system access to authorized users, processes acting on behalf of authorized users, or devices (including other information systems). | AWS Identity and Access Management (IAM) can help you with access permissions and authorizations by checking for IAM passwords and access keys that are not used for a specified time period. If these unused credentials are identified, you should disable and/or remove the credentials, as this may violate the principle of least privilege. This rule requires you to set a value to the maxCredentialUsageAge (Config Default: 90). The actual value should reflect your organization's policies. | |
| AC.1.001 | Limit information system access to authorized users, processes acting on behalf of authorized users, or devices (including other information systems). | Amazon Elastic Compute Cloud (Amazon EC2) Security Groups can help manage network access by providing stateful filtering of ingress and egress network traffic to AWS resources.
