Protecting Data by Pattern

You can create a regular expression matched against content in data transmissions. Transmissions that contain strings that match the pattern in their data get matched.

Note - Use the Check Point supported regular expression syntax.

To create a data type representation of a pattern:

  1. In the Data Type Wizard, select Pattern (regular expressions).

  2. Click Next.

  3. Enter a pattern to match against content.

  4. Click Add.

  5. Enter as many regular expressions as you want in this data type.

    You must go for one of these options to match data type:

    • If the pattern is matched even once.

    • Allow it until a given number of times.

      For example, if you want to ensure that no one can send an email that contains a complete price-list of five products, set the pattern to "^[0-9]+(\.[0-9]{2})?$" and set the Number of occurrences to 5.

  6. Click Next.

  7. Click Finish.

  8. (Optional) To add more parameters to the Data TypeClosed Classification of data in a Check Point Security Policy for the Content Awareness Software Blade., select the checkbox. Click Finish.
