Operational Best Practices for Esquema Nacional de Seguridad (ENS) Low
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 Spain Esquema Nacional de Seguridad (ENS) Low framework controls and AWS managed Config rules. Each Config rule applies to a specific AWS resource, and relates to one or more Spain ENS Low controls. A Spain ENS control can be related to multiple Config rules. Refer to the table below for more detail and guidance related to these mappings.
This sample conformance pack template contains mappings to controls within the Spain ENS Low framework, as last updated on 2020/10/23.

| Art. 25 | To help with data back-up processes, ensure your Amazon Redshift clusters have automated snapshots. When automated snapshots are enabled for a cluster, Redshift periodically takes snapshots of that cluster. By default, Redshift takes a snapshot every eight hours or every 5 GB per node of data changes, or whichever comes first. | |
| Art. 25 | The backup feature of Amazon RDS creates backups of your databases and transaction logs. Amazon RDS automatically creates a storage volume snapshot of your DB instance, backing up the entire DB instance. The system allows you to set specific retention periods to meet your resilience requirements. | |
| Art. 25 | Enable this rule to check that information has been backed up. It also maintains the backups by ensuring that point-in-time recovery is enabled in Amazon DynamoDB. The recovery maintains continuous backups of your table for the last 35 days. | |
| Art. 25 | An optimized instance in Amazon Elastic Block Store (Amazon EBS) provides additional, dedicated capacity for Amazon EBS I/O operations. This optimization provides the most efficient performance for your EBS volumes by minimizing contention between Amazon EBS I/O operations and other traffic from your instance. | |
| Art. 25 | When automatic backups are enabled, Amazon ElastiCache creates a backup of the cluster on a daily basis. The backup can be retained for a number of days as specified by your organization. Automatic backups can help guard against data loss. If a failure occurs, you can create a new cluster, which restores your data from the most recent backup. | |
| Art. 25 | Amazon Simple Storage Service (Amazon S3) Cross-Region Replication (CRR) supports maintaining adequate capacity and availability. CRR enables automatic, asynchronous copying of objects across Amazon S3 buckets to help ensure that data availability is maintained. | |
| Art. 25 | Amazon Simple Storage Service (Amazon S3) bucket versioning helps keep multiple variants of an object in the same Amazon S3 bucket.
