Organization
The Organization category includes Sharing, Apps and Address Lists. Sharing allows us to identify domains with whom we want to share free/busy data.
Apps are cloud friendly Exchange add-on applications. Exchange 2013 includes 3 Apps; Bing Maps, Suggested Appointments, and Action Items. We can expect more Apps from independent software vendors. These will be made available from the Office App store.
Lastly we have the Organization | Address Lists sub-category:
Protection
The Protection category brings the new Anti-malware options. To put this into context, I refer you to the announcement Microsoft made here: Important Changes to Forefront Product Roadmaps. Basically many of the Forefront products will be discontinued, including the on-premises Forefront Protection 2010 for Exchange (FPE).
With the on-premises FPE out of the equation, Microsoft is promising to improve the message hygiene it provides out-of-the-box. This is where the anti-malware functionality fits into the picture. Of course Microsoft will continue advancing Forefront Online Protection for filtering emails at the cloud.
Here is what the Anti-malware default policy looks like:
There isn't much to configure. We can choose how the malware is to be deleted and the type of notifications sent when malware is detected. Looks like there will be plenty of opportunity for products like IMF Tune to beef this up.
