Input Validation Is Not The Answer

I just sent a piece of e-mail to my team about input validation and SQL injection and it occurred to me that I've been meaning to get into this here, too: If you're trying to solve a SQL injection problem, input validation is NOT the answer! There, I've

LogParser, Event Logs, and Vista

LogParser is one of my absolute favorite tools, particularly for doing incident response. I use it a lot to extract and order data into a timeline (hmmm...that's a good topic for a future post). When I moved to Vista, I found one annoyance, though. The
