Security Insights: What it Takes to Protect the Institution and its Customers. Debbie Wheeler, CISO at Fifth Third BankCorp, explains how to secure business and reduce risk. Wheeler: Fraud happens in two primary ways: When resources internal to a bank take advantage of their position, their access or processes to commit fraud, and when customers fail to educate themselves about the risks associated with their activities online, or fail to take the necessary steps to protect their information. Customers want to know that the information they have entrusted to your care is secure.”]
