Operational Best Practices for NIST 1800 25

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 NIST 1800-25 and AWS managed Config rules. Each AWS Config applies to a specific AWS resource,and relates to one or more NIST 1800-25 controls. A NIST 1800-25 control can be related to multiple AWS Config rules. Refer to the table below for more detail and guidance related to these mappings.

Control ID	Control Description	AWS Config Rule	Guidance
ID.AM-2	Software platforms and applications within the organization are inventoried	ec2-instance-managed-by-systems-manager	An inventory of the software platforms and applications within the organization is possible by managing Amazon Elastic Compute Cloud (Amazon EC2) instances with AWS Systems Manager. Use AWS Systems Manager to provide detailed system configurations, operating system patch levels, services name and type, software installations, application name, publisher and version, and other details about your environment.
ID.AM-2	Software platforms and applications within the organization are inventoried	ec2-managedinstance-association-compliance-status-check	Use AWS Systems Manager Associations to help with inventory of software platforms and applications within an organization. AWS Systems Manager assigns a configuration state to your managed instances and allows you to set baselines of operating system patch levels, software installations, application configurations, and other details about your environment.
ID.AM-2	Software platforms and applications within the organization are inventoried	ec2-stopped-instance	Enable this rule to help with the baseline configuration of Amazon Elastic Compute Cloud (Amazon EC2) instances by checking whether Amazon EC2 instances have been stopped for more than the allowed number of days, according to your organization's standards.
ID.AM-2	Software platforms and applications within the organization are inventoried	eip-attached	This rule ensures Elastic IPs allocated to a Amazon Virtual Private Cloud (Amazon VPC) are attached to Amazon Elastic Compute Cloud (Amazon EC2) instances or in-use Elastic Network Interfaces. This rule helps monitor unused EIPs in your environment.
ID.AM-2	Software platforms and applications within the organization are inventoried	vpc-network-acl-unused-check	This rule ensures that Amazon Virtual Private Cloud (VPC) network access control lists are in use. Monitoring for unused network access control lists can assist in accurate inventory and management of your environment.
ID.RA-1	Asset vulnerabilities are identified and documented	rds-automatic-minor-version-upgrade-enabled	Enable automatic minor version upgrades on your Amazon Relational Database Service (RDS) instances to ensure the latest minor version updates to the Relational Database Management System (RDBMS) are installed, which may include security patches and bug fixes.
ID.RA-1	Asset vulnerabilities are identified and documented	ec2-managedinstance-patch-compliance-status-check	Enable this rule to help with identification and documentation of Amazon Elastic Compute Cloud (Amazon EC2) vulnerabilities. The rule checks if Amazon EC2 instance patch compliance in AWS Systems Manager as required by your organization's policies and procedures.
ID.RA-1	Asset vulnerabilities are identified and documented	elastic-beanstalk-managed-updates-enabled	Enabling managed platform updates for an Amazon Elastic Beanstalk environment ensures that the latest available platform fixes, updates, and features for the environment are installed. Keeping up to date with patch installation is a best practice in securing systems.
ID.RA-1	Asset vulnerabilities are identified and documented	guardduty-enabled-centralized	Amazon GuardDuty can help to monitor and detect potential cybersecurity events by using threat intelligence feeds. These include lists of malicious IPs and machine learning to identify unexpected, unauthorized, and malicious activity within your AWS Cloud environment.
PR.AC-1	Identities and credentials are issued, managed, verified, revoked, and audited for authorized devices, users and processes	ec2-instance-profile-attached	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.
PR.AC-1	Identities and credentials are issued, managed, verified, revoked, and audited for authorized devices, users and processes	ecs-task-definition-user-for-host-mode-check	If a task definition has elevated privileges it is because the customer has specifically opted-in to those configurations. This control checks for unexpected privilege escalation when a task definition has host networking enabled but the customer has not opted-in to elevated privileges.
PR.AC-1	Identities and credentials are issued, managed, verified, revoked, and audited for authorized devices, users and processes	iam-no-inline-policy-check	Ensure an AWS Identity and Access Management (IAM) user, IAM role or IAM group does not have an inline policy to control access to systems and assets. AWS recommends to use managed policies instead of inline policies. The managed policies allow reusability, versioning and rolling back, and delegating permissions management.
PR.AC-1	Identities and credentials are issued, managed, verified, revoked, and audited for authorized devices, users and processes	iam-policy-no-statements-with-full-access	Ensure IAM Actions are restricted to only those actions that are needed. Allowing users to have more privileges than needed to complete a task may violate the principle of least privilege and separation of duties.
PR.AC-1	Identities and credentials are issued, managed, verified, revoked, and audited for authorized devices, users and processes	access-keys-rotated	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.
PR.AC-1	Identities and credentials are issued, managed, verified, revoked, and audited for authorized devices, users and processes	emr-kerberos-enabled	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.
PR.AC-1	Identities and credentials are issued, managed, verified, revoked, and audited for authorized devices, users and processes	iam-group-has-users-check	AWS Identity and Access Management (IAM) can help you incorporate the principles of least privilege and separation of duties with access permissions and authorizations, by ensuring that IAM groups have at least one user.

PR.AC-1	Identities and credentials are issued, managed, verified, revoked, and audited for authorized devices, users and processes	iam-policy-no-statements-with-admin-access	AWS Identity and Access Management (IAM) can help you incorporate the principles of least privilege and separation of duties with access permissions and authorizations, restricting policies from containing "Effect": "Allow" with "Action": "*" over "Resource": "*". Allowing users to have more privileges than needed to complete a task may violate the principle of least privilege and separation of duties.
PR.AC-1	Identities and credentials are issued, managed, verified, revoked, and audited for authorized devices, users and processes	iam-root-access-key-check	Access to systems and assets can be controlled by checking that the root user does not have access keys attached to their AWS Identity and Access Management (IAM) role. Ensure that the root access keys are deleted. Instead, create and use role-based AWS accounts to help to incorporate the principle of least functionality.
PR.AC-1	Identities and credentials are issued, managed, verified, revoked, and audited for authorized devices, users and processes	iam-user-mfa-enabled	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 a user name and password. Reduce the incidents of compromised accounts by requiring MFA for users.
PR.AC-1	Identities and credentials are issued, managed, verified, revoked, and audited for authorized devices, users and processes	iam-user-no-policies-check	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.
PR.AC-1	Identities and credentials are issued, managed, verified, revoked, and audited for authorized devices, users and processes	iam-user-unused-credentials-check	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.
PR.AC-1	Identities and credentials are issued, managed, verified, revoked, and audited for authorized devices, users and processes	secretsmanager-rotation-enabled-check	This rule ensures AWS Secrets Manager secrets have rotation enabled. Rotating secrets on a regular schedule can shorten the period a secret is active, and potentially reduce the business impact if the secret is compromised.
PR.AC-3	Remote access is managed.	autoscaling-launch-config-public-ip-disabled	If you configure your Network Interfaces with a public IP address, then the associated resources to those Network Interfaces are reachable from the internet.
