#MAXMIND FRAUD RISK SCORE MANUAL#
The minFraud service helps companies prevent fraudulent online transactions and reduce manual review. The typical types of changes that occur are: MaxMind is a leading provider of IP geolocation and fraud detection data services. Since the data is derived from updates individual ISP's provide the various registries the frequency varies depending on the volume and timing of those updates. Conversely if an IP address is reassigned to a new location the new GeoIP data might result in a higher risk score.Ī new GeoIP data is available from RSA every month, however it's up to each individual customer to decide how frequently they want to talke the latest file. For example a newly assigned IP address not in theGeoIP data will generate a higher risk score than it would if the GeoIP database had been updated. Not updating the GeoIP data file regularly can cause some users to have a higher risk score and some a lower risk score.
In particular since most retail ISP's allocate IP addresses dynamically we can't assume that a home user will maintain the same IP address indefinitely, so when their IP address changes we can asses the probability that the same computer was reassigned a different IP address by comparing the old and newGeoIP data. Some of these values can then be used in Policies (For example DENY all requests originating in Nigeria) and also factor in to the overall risk score. If included in your contract RSA will provide an updated data file around the middle of each month through your RSA Central reporting account.īy looking up the Geoip data for the source IP of an incoming request we can determine the Country, State, City, ISP and approx Latitude and Longitude of the computer making the request. RSA provides geographic IP location information with your initial build. The risk score criteria can be customized to better fit the needs of the business. The CCFD service checks credit card orders and returns a risk score on a 0-10 scale.
