The articles featured here will primarily highlight current security issues and solutions that may impact small business owners with office networks.  The target audience is the successful business leader with limited or no access to their own in-house IT support.  We hope that our suggestions here will enable you to prevent many problems before they strike.

This is “mostly” a Windows shop.  Most of the information we present will be centered around securing Microsoft Windows products.

I would like to draw your attention to the Related links in the side bar on your right.  They are a great place to start your education.  I urge you to take a few minutes to learn about the types of threats you and your employees may face daily when interacting with the Internet.  Topics include Phishing, SpyWare or MalWare, Virus protection and more.  Becoming Internet “street-wise” and learning to be just paranoid enough to suspect that odd email is a good thing nowadays.

The Internet really is a jungle, and knowledge is the best defense.
