My friend Brian writes Databases, Infrastructure, and Security and like me, he writes about an eclectic mix that goes beyond SQL to Windows and life, but the part that makes me recommend that you visit his blog is the emphasis on security. Brian is always there with reminders about vulnerabilities and he's got the Active Directory experience to bake the whole cake and not just logins and permissions within SQL. Worth reading!
