how_to_implement: You must install the AWS App for Splunk (version 5.1.0 or later)
  and Splunk Add-on for AWS (version 4.4.0 or later), then configure your CloudTrail
  inputs. This search works best when you run the "Previously Seen AWS Provisioning
  Activity Sources" support search once to create a history of previously seen locations
  that have provisioned AWS resources.
known_false_positives: "This is a strictly behavioral search, so we define \"false\
  \ positive\" slightly differently. Every time this fires, it will accurately reflect\
  \ the first occurrence in the time period you're searching over plus what is stored\
  \ in the cache feature. But while there are really no \"false positives\" in a traditional\
  \ sense, there is definitely lots of noise.\\\n This search will fire any time a\
  \ new country is seen in the **GeoIP** database for any kind of provisioning activity.\
  \ If you typically do all provisioning from tools inside of your country, there\
  \ should be few false positives. If you are located in countries where the free\
  \ version of **MaxMind GeoIP** that ships by default with Splunk has weak resolution\
  \ (particularly small countries in less economically powerful regions), this may\
  \ be much less valuable to you."
