I stumbled upon a site yesterday dealing with blog security specifically and felt it was worth posting.

"BlogSecurity is the only organization that deals with web blog security exclusively. We understand that it is difficult to keep track of the latest security vulnerabilties and version updates, and we believe you shouldn’t have to."

"Our aim is to provide you with the security advice, services, tools and information you need to better secure your blog, allowing you to focus on the important stuff, your content."
