Amazon Detective identifies additional information related to a finding group based on data in your behavior graph collected within the last 45 days. Detective presents this information as a finding with the Informational severity. Evidence provides supporting information that highlights an unusual activity or unknown behavior that is potentially suspicious when viewed within a finding group. This might include newly observed geolocations or API calls observed within the scope time of a finding. Evidence findings are only viewable in Detective and are not sent to AWS Security Hub.
Detective determines the location of requests using MaxMind GeoIP databases.
MaxMind reports very high accuracy of their data at the country level,
although accuracy varies according to factors such as country and type of
IP. For more information about MaxMind, see MaxMind IP Geolocation
You can observe evidence for different principal types (such as IAM user or IAM role). For some evidence types, you can observe evidence for all accounts. This means evidences affect your entire behavior graph. If an evidence finding is observed for all accounts, you will also see at least one additional informational evidence finding of the same type for an individual IAM role. For example, if you see a New geolocation observed for all accounts finding, you will see another for New geolocation observed for a principal.
