Summary

Added notes clarifying that CloudFront DNS configuration checks apply to 'classic' distributions and updated check descriptions

Security assessment

The changes are documentation clarifications about performance check scope without any security-specific context or references to security vulnerabilities/features. The DNS configuration check improvements are operational rather than security-focused.
