RegEx Pattern for Danish SSN in Data Filtering Profile

RegEx Pattern for Danish SSN in Data Filtering Profile

Created On 09/26/18 13:49 PM - Last Modified 02/07/19 23:46 PM



The Danish SSN is composed of 10 digits with a dash/hyphen between the 6th and 7th digit (for example, 120965-1472). The first 6 digits are the date of birth (day, month, year) and the last 4 digits uniquely identify people born on the same day. To detect outbound emails that include a Danish SSN, a custom regex pattern can be applied to a data filtering profile on the Palo Alto Networks firewall.


In PAN-OS, each regex pattern must include a fixed 7-byte string in order to be valid.  The string "subject" can be included to key the pattern for an email. Therefore, the basic regex pattern, valid in PAN-OS, would be the following:





Note: The regex above can be enhanced to further limit the pattern matches.
