Understanding the value of persistent document security with IRM and DLP

Bodyguard.png
Great progress is being made here at integrating many DLP vendors with our information rights management (IRM) document security solution. Keep an eye out over the coming months for some sneak previews into this work. Our integration with Symantec DLP is also in the pipe for a vast increase in functionality as part of an integration with Oracle IRM 11g.

DLP and IRM together make a lot of sense. DLP is an excellent technology for watching systems and network perimeters to recognize content as sensitive so it can monitor/warn/block activities. For example, if you try to email a sensitive doc out of the business, DLP might block the email due to policy.

But DLP is an internal solution. No third party is going to let you monitor their networks and systems to protect anything that you send out, or that the third party is doing on your behalf. Especially with many looking to the cloud to store and manage content, does the cloud integration with your DLP? Does the cloud provide the same level of security and integrate with your existing internal security technologies and policies? So, many DLP implementations involve monitoring the perimeter of your network trying to prevent things leaving - or monitor your USB ports trying to prevent you from copying information to USB memory. Your USB port is an example of many different "perimeters" that DLP needs to monitor if it can.

IRM on the other hand protects information more directly. You seal a document and it is encrypted. You can send sealed documents to external parties - or allow third parties to create sealed content because they are working for you - but policy and audit still apply. The solution can be used in third party networks because the IRM solution only monitors/controls sealed documents - it does not monitor the third party's networks or systems or intervene in third party processes that have nothing to do with you.

Recent interest from both customers as well as partners and vendors has sparked a lot of discussion within the walls of Oracle and one of our expert IRM consultants came up with a great way to explain the abilities of these two technologies and how they work well together. I thought i'd share his analogy here;

 


  • DLP is like a police force. It watches as many things as it can for breaches of policy and intervenes in some way when it can. It needs to monitor all the channels that you identify as a potential risk, and its effectiveness stops at your border. You need constant adjustment to be confident that you are catching everything you should catch, and the trick is defining a comprehensive set of policies without making everyone feel that they are living in a police state. In practice, this might mean that you define very simple policies and warn rather than block. Once a document has left your borders, you have no further control and no means of revoking access.


  • IRM is more like a bodyguard. It goes wherever the sensitive assets go - even if they go beyond your border - but it takes no interest in anything that is not sealed. It applies policy consistently even if policy changes over time - so you can revoke access to external copies long after sending them. However, it only protects the assets it is assigned to protect, so the trick is using business process or automation to ensure that all sensitive assets are sealed. The automation could be managed by DLP.
