Here are a few basic sites. Wikipedia even has one.

I hope this gives you some food for thought. If you need something more imaginative, you can grab a copy of The Shadow Warriors.
The Shadow Warriors is a genre-busting novel of suspense, incorporating international locales (Singapore, Hong Kong, Boston, Brussels and Germany), technology (software agents) and the derring-do at a German university. The story is framed by an outbreak of information warfare. Emma Lee Davis, a web security consultant, must dredge up a painful summer in her past to discover a means to end the info-war that has disrupted civilization.
