120 Barracuda Spam Firewall Administrator’s Guide
Setting Up Subject and Body Filtering
You can use compliance buttons to filter information containing credit card, information, privacy, or
HIPAA information that are confidential or sensitive material for outbound mail. These buttons
contain pre-set patterns. When selected, they are inserted as keyword listings that have precoded
patterns that contain regular expressions. Outbound e-mails that contain these patterns are blocked.
This information include:
• Credit Cards: Messages sent through the Barracuda Outbound Spam Firewall containing
recognizable Master Card, Visa, American Express, Diners Club or Discover card numbers are
blocked or quarantined when this pattern is used.
• Social Security: Messages sent with valid social security numbers are blocked or quarantined
when using this pattern.
• Privacy: Messages are blocked or quarantined for privacy if they contain two or more of the
following information: Address, Birthday, Social Security number, credit card number, driver's
license number, phone number, or expiration date.
• HIPAA: Messages are blocked or quarantined if they are identified by the Privacy option above
or these messages contain two or more phrases indicative of private medical information.
These patterns help minimize the misuse of confidential information for outbound mails but they do
not guarantee that these patterns cannot be overrided or that misuse of confidential be completely
prevented. These patterns cannot take away the importance of educating your employees on
recognizing misuse of confidential information.
