I've just put up a Database Security Brief; the first of many to come. http://www.databasesecurity.com/dbsec-briefs.htm It's called a brief because there's enough meat to make it interesting but not enough to make it a paper ;) This brief, Snagging Security Tokens to Elevate Privileges, details how a database server running as a low privileged user on Windows can still provide an attacker with the ability to gain elevated privileges on the network and suggests a change it security policy to mitigate the risk. As a side note, this affects all network servers that offer OS based authentication - not just database servers. Cheers, David
