Avoid fingerprinting columns with repetitive values

Columns having repetitive values are quite common in databases. Fingerprinting such columns may cause performance issues both during the fingerprinting stage and real- time analysis. Fingerprinted repetitive fields may lead to large amounts of records matching analyzed transactions, and it will take time for the policy engine to go over the results.

For now, Forcepoint recommends that you avoid fingerprinting columns with repetitive values. Many times, such columns have a very limited range of values, and they actually can be turned into a dictionary and attached to other policy rules in a database policy.
