Introduction

This document provides sample data that can be used to test Data Loss Prevention (DLP) policies in order to confirm that they work as intended.

Prerequisites

Requirements

Cisco recommends that you have the DLP feature key installed and in use.

Components Used

The information in this document is based on these software and hardware versions:

- ESA that runs AsyncOS 11.x or later.

- DLP engine 1.0.18.d7b4601 or later (can be obtained with the dlpstatus command from the CLI).

The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, ensure that you understand the potential impact of any command.

Examples

In order to utilize the sample data, complete these steps:

1. Create the DLP policy (for example, American Banking Association (ABA) Routing Numbers) and attach it to an Outgoing Mail Policy.

2. Choose Submit > Commit in order to commit the changes.

3. Send an email through the ESA which will hit the newly created DLP policy on the Outgoing Mail Policy it was applied to.

The test email should include the sample data, which can be placed in the body (for example, ABA Routing Number: 800000080).

4. Review the mail logs or Message Tracking in order to confirm that a DLP violation had occurred.
