Summary

Improved security in WAF script: added JSON validation, secure logging, error handling, sensitive data redaction, and automatic cleanup

Security assessment

Changes include: 1) JSON response validation to prevent processing malicious payloads; 2) Secure log file handling (chmod 600); 3) Lock token redaction in outputs; 4) EXIT trap for guaranteed cleanup; 5) AWS CLI output sanitization; 6) Stricter error handling. These address risks of credential leakage, insecure temp files, and command injection via malformed responses.
