- Move Security Hub related code to a dedicated include/securityhub_integration file - Check that Security Hub is enabled in the target region before beginning checks when -S is specified - Add error handling to the batch-import-findings call - Add CHECK_ASFF_TYPE variables to all CIS checks to override the default - Add support for CHECK_ASFF_RESOURCE_TYPE variables which override the default 'AwsAccount' value for the resource a finding relates to. - Add CHECK_ASFF_RESOURCE_TYPE variables to all checks where there is a suitable value in the schema - Remove json-asff output for info messages as they are not appropriate for possible submission to Security Hub - Update the README to cover Security Hub integration - Add an IAM policy JSON document that provides the necessary BatchImportFindings permission for Security Hub - Remove trailing whitespace and periods in pass/fail messages to be consistent with the majority of messages, to prevent future tidy-up from changing the finding IDs
