This is a in depth look at WP security. I think it is going to help some here. I hope you enjoy.
I love wordpress (most of the time :-)
From the Youtube Publisher:
As part of our Make Waves campaign for 2012, we believe every WordPress site should be safe and secure. That means having a backup strategy, but also making sure your site is clean of malware and security holes. We asked our good friend and security expert Dre Armeda, CEO and co-founder at Sucuri, to share security tips for locking down your WordPress site via a free webinar. You'll learn how to do basic garage cleaning on your WordPress site, what security hacks Sucuri is seeing infected and tips on helping reduce your site risk.
PS. I'm Not sure how to embed youtube on this forum yet if it is possible.
