4.8 Ensure Database has delete protection enabled

Description

Ensure that delete protection is enabled on database instances to prevent accidental or unauthorized deletion. This setting safeguards critical databases by requiring explicit disabling of delete protection before deletion, reducing the risk of data loss through human error or malicious activity.

Rationale

Delete protection provides a safeguard against inadvertent or malicious deletion of critical databases. By requiring deliberate action to disable deletion protection, organizations mitigate risks associated with accidental data deletion and enhance the overall resilience of their data storage platform.

Impact

Failure to enable delete protection increases the risk of irreversible data loss, potential service disruption, and operational downtime.

Audit Procedure

Using AWS CLI

To check whether delete protection is enabled on your DynamoDB tables, use the following command for each table:

aws dynamodb describe-table --table-name <your-table-name> \
  --query "{TableName: Table.TableName, DeleteProtectionEnabled: Table.DeletionProtectionEnabled}" \
  --output table

• Replace with your DynamoDB table name.
• This will return True if delete protection is enabled, False otherwise.

Expected Result

DeleteProtectionEnabled returns True for all critical DynamoDB tables.

Remediation

Using AWS CLI

To enable delete protection on an existing DynamoDB table, use the following command:

aws dynamodb update-table \
    --table-name my-table \
    --deletion-protection-enabled

• Replace with your DynamoDB table name.
• Delete protection prevents the table from being deleted until the protection is disabled explicitly.

Default Value

By default, delete protection is not enabled on DynamoDB tables.
