AWS autoscaling documentation change
Summary
Updated terminology from 'Auto Scaling group' to 'Amazon EC2 Auto Scaling group' throughout the document for consistency
Security assessment
The changes are purely terminological updates to use the full service name ('Amazon EC2 Auto Scaling group') consistently. There are no modifications to security-related content, vulnerability disclosures, or new security guidance. The existing security-related information about instance protection mechanisms remains unchanged.
