Data Filtering Profiles

Data filtering profiles prevent sensitive information such as credit card or social security numbers from leaving a protected network. The data filtering profile also allows you to filter on key words, such as a sensitive project name or the word confidential. It is important to focus your profile on the desired file types to reduce false positives. For example, you may only want to search Word documents or Excel spreadsheets. You may also only want to scan web-browsing traffic, or FTP.
You can use default profiles, or create custom data patterns. There are two default profiles:
  • CC# (Credit Card)—Identifies credit card numbers using a hash algorithm. The content must match the hash algorithm in order for data to be detected as a credit card number. This method will reduce false positives.
  • SSN# (Social Security Number)—Uses an algorithm to detect nine digit numbers, regardless of format. There are two fields: SSN# and SSN# (no dash).
