The OpenUI provides advanced security settings to fix some known holes in different versions of Miva Merchant. These includes ways that hackers
can bypass important steps such as: Shipping, Payment and Tax Calculations.
Also, becoming more common these days is Hackers using online stores to test their lists of stolen credit cards. The OpenUI Security Settings
provide a way to insert delays based on the number of Payment Failures a shopper has. These delays make your store almost worthless to a Hacker
trying to do this. It becomes even more important as many Payment Gateways now charge a per-transaction fee, and a hacker running 1000's of
credit card attempts thru your store can cost you real $$$.
