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).
