A manager for a hospital billing system wants to display the last four digits of a credit card number when printing invoices.
Which credit card security action does this?
To display only the last four digits of a credit card number for security purposes, the appropriate action is to mask or hide the remaining digits. This is commonly done by replacing the sensitive portions with 'X' characters. This action is often referred to as 'X-Out', where most of the digits are replaced with 'X's, leaving only the last four digits visible. This ensures that while the credit card number is protected, enough information is provided for reference purposes.
The number of X'd out digits depends on the length of the credit card numbers. Ten digits are X'd out for credit cards that have 13 through 15 digits. Twelve digits are X'd out for credit cards that have 16 digits. If your application does not require sending the entire credit card number in the response, Citrix recommends that you enable this action to mask the digits in the credit card numbers.
A. X-Out X-Out is typically used to mask or hide sensitive information, such as credit card numbers, by replacing part of the data with "X" characters, except for the last few digits. This helps protect sensitive information while still providing some information for reference purposes.
Credit card protection The Application Firewall offers an option to inspect the headers and body of the response and either removes or x-outs the Credit Card numbers before forwarding the response to the client. Currently Application Firewall offers protection for the following major credit cards: American Express, Diners Club, Discover, JCB, MasterCard, and Visa. The x-out action works independent of the Block action.
