Il-Sung Lee and Art Rask’s whitepaper, Auditing in SQL Server 2008, just hit the web. Congratulations!
I just wanted to add to what Il-Sung already has said about this paper that this is a great resource that will answer some of the big questions we get repeatedly asked. Such as performance impact – the whitepaper includes some hard numbers about performance impact of some workloads typical of customer environments. If you have any interest in SQL Server Audit, this is the paper for you! Hope you enjoy.
