Exchange 2013 Data Loss Prevention (Part 3)

By Nuno Mota,

In this third and last part of the article, we will explore Policy Tips, test these policies and look at all the information that DLP logs.

So far in this article series we have seen what the purpose of the new Data Loss Prevention feature of Exchange 2013 Preview is, how it works and how to create DLP Policies using both the Exchange Administration Center and the Exchange Management Shell.

Policy Tips

In the first part of this article, we say that we can notify a sender if he/she is about to send information that violates a DLP Policy. But how is the sender notified? By introducing a Policy Tip notification message!

These Policy Tips are similar to Mail Tips introduced in Exchange 2010 as they display a notification message to Outlook users when they are composing an e-mail. Obviously they only show up if Exchange detects something in the e-mail that violates a DLP Policy currently in place and if this policy has a rule to notify the sender.

A great thing about Data Loss Prevention [DLP] and Policy Tips is that Exchange will automatically look into a message's subject, body and even attachments when evaluating conditions within policies. This means that if a user is writing an e-mail with a perfectly normal body text but attaches an Excel document with credit card details, then a Policy Tip notification that you create will be shown to the sender in Outlook reminding him/her of the policy against such action.

The benefit of Policy Tips is that if a user writing an e-mail is made aware in real-time that he/she might be violating a corporate policy, then he/she is less likely to violate it.

Now let's test a few DLP Policies and look how these Policy Tips look like.
