Editor's note: It's that time again -- time for the fifty-first in our regular weekly series of PowerBlog Reviews of business weblogs.

We like to think that all the blogs we review in our PowerBlog Review series are helpful resources. But The Security Mentor has to be one of the most practical of all the blogs we've looked at.

The Security Mentor provides "advice for normal people about computer and information security from Beryllium Sphere(R) LLC." (By the way, aren't blogs great, with their plain English topic descriptions? How different from traditional websites they are, where you can read the About section and still not have a clue what the business does.)

The blog is a client resource and marketing tool for Beryllium Sphere LLC, a computer security consulting company in Redmond, Washington, USA. Fred Wamsley is the owner and chief blogger. His company specializes in serving small businesses, especially the SOHO (small office/home office) market.

Fred has a crystal clear idea of who he is trying to reach with his blog, saying:

'My target reader is someone motivated enough to do online research but unwilling to become a full-fledged nerd. The "computer person by default" at a small business, who becomes the de facto IT department because "s/he knows about those computers", is a perfect example.'
