AWS code-library medium security documentation change
Summary
Updated AWS Connect bash script to improve security and reliability: added strict error handling, restricted log file permissions, AWS CLI validation, JSON parsing with jq, automatic resource cleanup, and secure credential handling.
Security assessment
Added chmod 600 for log files to prevent unauthorized access to sensitive data like passwords and credentials. Implemented automatic cleanup of AWS resources using ERR/EXIT traps to prevent resource leakage. These changes directly address security risks of accidental credential exposure and orphaned cloud resources.
