Operational Best Practices for NERC CIP BCSI - AWS Config

Operational Best Practices for NERC CIP BCSI

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 North American Electric Reliability Corporation Critical Infrastructure Protection Standards (NERC CIP) for BES Cyber System Information (BCSI), CIP-004-7 & CIP-011-3, and AWS Config managed rules. Each AWS Config rule applies to a specific AWS resource, and relates to one or more NERC CIP controls applicable to BCSI. A NERC CIP 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
CIP-004-7-R6-Part 6.1 Each Responsible Entity shall implement one or more documented access management program(s) to authorize, verify, and revoke provisioned access to BCSI pertaining to the “Applicable Systems” identified in CIP-004-7 Table R6 – Access Management for BES Cyber System Information that collectively include each of the applicable requirement parts in CIP-004-7 Table R6 – Access Management for BES Cyber System Information. To be considered access to BCSI in the context of this requirement, an individual has both the ability to obtain and use BCSI. Provisioned access is to be considered the result of the specific actions taken to provide an individual(s) the means to access BCSI (e.g., may include physical keys or access cards, user accounts and associated rights and privileges, encryption keys). Part 6.1: Prior to provisioning, authorize (unless already authorized according to Part 4.1.) based on need, as determined by the Responsible Entity, except for CIP Exceptional Circumstances: 6.1.1. Provisioned electronic access to electronic BCSI

opensearch-access-control-enabled

Ensure fine-grained access control is enabled on your Amazon OpenSearch Service domains. Fine-grained access control provides enhanced authorization mechanisms to achieve least-privileged access to Amazon OpenSearch domains. It allows for role-based access control to the domain, as well as index, document, and field-level security, support for OpenSearch dashboards multi-tenancy, and HTTP basic authentication for OpenSearch and Kibana.

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.

s3-bucket-acl-prohibited

This rule checks to see if Access Control Lists (ACLs) are used for access control on Amazon S3 Buckets. ACLs are legacy access control mechanisms for Amazon S3 buckets that predate AWS Identity and Access Management (IAM). Instead of ACLs, it is a best practice to use IAM policies or S3 bucket policies to more easily manage access to your S3 buckets.
