How Data Loss Prevention Software Works


Recently I was asked to propose a solution that can ensure protection of Intellectual Property. I categorized Intellectual Property in to following items:

Application source code, project data, customer list, new designs, patentable ideas, financial reports, minutes of the meeting, plans, employee information etc

The challenge seem to be huge as the expectation is to effectively block IP going through laptops, dasktops or any other source.

Initially it seemed impossible till I came across End Point Data Loss Prevention solutions.

As per the concept of DLP, an agent sits on every machine. It ensures to synchronize the policies with the centralized policy management server and protect information leaking out of the system.Typically if you stop the agent you are gone! You just need to rely on the agent, which does the trick even when you are in offline mode.

If you are working from home or out of office network or connecting to USB internet the information in that system is still secure. However in offline mode the policies that were set while in online mode gets enforced. If you want policy synchronization to kick off, you need to be online with the network.

Best part is with DLP you can also monitor users taking printout of a classified document.

I evaluated TrendMicro, McAfee and RSA. RSA was good, McAfee was next better and TrendMicro also behaved well.
