Under the Guidelines, a bank must protect against unauthorized access to or use of customer information that could result in substantial harm or inconvenience to any customer. Substantial harm or inconvenience is most likely to result from improper access to sensitive customer information because this type of information is most likely to be misused, as in the commission of identity theft.
For purposes of this Guidance, sensitive customer information means a customer’s name, address, or telephone number, in conjunction with the customer’s social security number, driver’s license number, account number, credit or debit card number, or a personal identification number or password that would permit access to the customer’s account. Sensitive customer information also includes any combination of components of customer information that would allow someone to log onto or access the customer’s account, such as user name and password or password and account number.
