Configuring data loss prevention signatures

The Network IPS appliance uses data loss prevention signatures that you create for predefined events, user-combined events, and user-defined events.

How Data Loss Prevention works

Data Loss Prevention inspects data packets as they move across the network, detecting the transmission of many types of confidential information. The feature can identify patterns such as credit card numbers, names, dates, dollar amounts, email addresses, social security numbers, United States phone numbers, and United States postal addresses in various protocols and content.

In addition to the preset signatures, you can create up to eight custom user-defined signatures. You can also create up to eight user-combined signatures by grouping combinations of preset and user-defined signatures. A user-combined signature functions as a single data set.
