Operational Best Practices for RBI MD-ITF - AWS Config

Operational Best Practices for RBI MD-ITF

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 Reserve Bank of India (RBI) Master Direction – Information Technology Framework and AWS managed Config rules. Each Config rule applies to a specific AWS resource, and relates to one or more RBI Master Direction – Information Technology Framework controls. An RBI Master Direction – Information Technology Framework control can be related to multiple Config rules. Refer to the table below for more detail and guidance related to these mappings.

Control ID Control Description AWS Config Rule Guidance
3.1(a) Identification and Classification of Information Assets.

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.
3.1(c ) Role Based Access Control

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.
3.1(c ) Role Based Access Control

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.
3.1(c ) Role Based Access Control

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 IAM user. Placing IAM users in groups based on their associated permissions or job function is one way to incorporate least privilege.
3.1(c ) Role Based Access Control

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.
3.1(c ) Role Based Access Control

iam-password-policy

The identities and the credentials are issued, managed, and verified based on an organizational IAM password policy. They meet or exceed requirements as stated by NIST SP 800-63 and the AWS Foundational Security Best Practices standard for password strength. This rule allows you to optionally set RequireUppercaseCharacters (AWS Foundational Security Best Practices value: true), RequireLowercaseCharacters (AWS Foundational Security Best Practices value: true), RequireSymbols (AWS Foundational Security Best Practices value: true), RequireNumbers (AWS Foundational Security Best Practices value: true), MinimumPasswordLength (AWS Foundational Security Best Practices value: 14), PasswordReusePrevention (AWS Foundational Security Best Practices value: 24), and MaxPasswordAge (AWS Foundational Security Best Practices value: 90) for your IAM Password Policy. The actual values should reflect your organization's policies.
3.1(c ) Role Based Access Control

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.
3.1(c ) Role Based Access Control

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.
3.1(c ) Role Based Access Control

iam-user-group-membership-check

AWS Identity and Access Management (IAM) can help you restrict access permissions and authorizations, by ensuring IAM users are members of at least one group. Allowing users more privileges than needed to complete a task may violate the principle of least privilege and separation of duties.
3.1(c ) Role Based Access Control

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 IAM 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 IAM users.
3.1(c ) Role Based Access Control

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.
3.1(c ) Role Based Access Control

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.
3.1(c ) Role Based Access Control

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.
3.1(c ) Role Based Access Control

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.
3.1(c ) Role Based Access Control

mfa-enabled-for-iam-console-access

Manage access to resources in the AWS Cloud by ensuring that MFA is enabled for all AWS Identity and Access Management (IAM) users that have a console password.
