  • protection (bool) – A Boolean that determines the value of the X-XSS-Protection HTTP response header. When this setting is true, the value of the X-XSS-Protection header is 1. When this setting is false, the value of the X-XSS-Protection header is 0.

  • mode_block (Optional[bool]) – A Boolean that determines whether CloudFront includes the mode=block directive in the X-XSS-Protection header. Default: false

  • report_uri (Optional[str]) – A reporting URI, which CloudFront uses as the value of the report directive in the X-XSS-Protection header. You cannot specify a ReportUri when ModeBlock is true. Default: - no report uri
