AWS lambda documentation change
Summary
Restructured documentation with new example application categories (File Processing, Database Integration, Scheduled Tasks) and added specific security-focused PDF encryption example
Security assessment
Added explicit documentation about a PDF encryption application that secures sensitive documents through automatic encryption. While this demonstrates security best practices, there's no evidence of addressing a specific vulnerability or security incident.
