Few security technologies have received as much attention over the past few years as Data Leakage Prevention (DLP) solutions have. The concept behind them is exciting, offering the ability to scan traffic on your network and in your systems, and assign rules-based protections to the data that you want to protect. Someone e-mailing out a copy of customer records with SSNs? The DLP system will block it or encrypt it on the fly. Someone trying to copy IP to a USB drive? Alert management and block the action. It can be a great way to protect your most critical information assets, but as many have found, it is not an end-all, be-all solution to your data leakage problems.
