The location latitude and longitude are used in the Zone Hopping Check rule. This rule checks the required speed of physical travel required for the user to make successive transactions from the IP addresses they used for access. If the users are traveling too fast, then you must conclude that either two people were accessing the account or the user did something, either intentionally or inadvertently, to mask their true location. CA suggests that you start by setting the values of the Zone Hopping Check rule to the default values provided. Based on performance, you can tune the settings of this rule to meet the requirements of your particular user base. In its default settings, you should expect the rule to fire about 0.02% of the time. The false positive rate for this rule is good at under 10:1.
