What new security features does Microsoft Office Sharepoint (MOSS) 2007 bring?

It seems like a long time since we launched Microsoft Office Sharepoint (MOSS) 2007 and it's great to see how many people are using it day to day. I remember at the Exchange, Vista and Office launch (almost a year ago) and the subsequent roadshow we made a point of showing how Sharepoint made life so much easier for information workers and IT Professionals alike.

Whilst researching a talk for the Sharepoint User Group I came across a nice article on TechNet Magazine titled 7 New Features That Enhance Sharepoint - it's a great overview of the new security features - well worth a read.
