USAGE:
`basename $0` -p <profile> -r <region> [ -h ]
Options:
-p <profile> specify your AWS profile to use (i.e.: default)
-r <region> specify an AWS region to direct API requests to
(i.e.: us-east-1), all regions are checked anyway
-c <check_id> specify a check number or group from the AWS CIS benchmark
(i.e.: "check11" for check 1.1, "check3" for entire section 3, "level1" for CIS Level 1 Profile Definitions or "forensics-ready")
-f <filterregion> specify an AWS region to run checks against
(i.e.: us-west-1)
-m <maxitems> specify the maximum number of items to return for long-running requests (default: 100)
-M <mode> output mode: text (defalut), mono, csv (separator is ","; data is on stdout; progress on stderr)
-k keep the credential report
-n show check numbers to sort easier
(i.e.: 1.01 instead of 1.1)
-l list all available checks only (does not perform any check)
-e exclude extras
-h this help
