Telling Your Superiors Their Financial Data Is At Risk?

alterimage asks: "I'm a Computer Science major at night, working by day in Accounting for a major telecom provider, with clients consisting of most the entities on Fortune's Top 20 Most Admired Companies of 2006 list. Daily, I see customer payments in excess of $50,000 come and go. Strangely enough, rather than have these payments conducted by an IVR system or over the Internet, the majority of these payments are conducted over the phone with individuals such as myself, who are instructed to write down, document all the specific banking information, and to keep them on hard-copy in an unlocked file cabinet that is accessible to anyone. Having experience with social engineering and fraud, I've already advised my boss that it's probably not a good idea for those bank routing and account numbers to be laying around unsecured, and was told that I'm over-reacting. So I ask Slashdot: At what point should the human aspect of security be considered in the business environment? Should I just smile, nod, and play along in this situation?"
