We are all in need for cyber pre-flagging of individuals with potential for violent acts (especially recently reoccurring school shooting), pedophile activity, etc. I am not sure how that can be done though, but it may give you an idea or direction.

Hmm thanks Maria. That's another interesting area. Though it would take a lot of resources to achieve that.

One author recommended in this area is Eoghan Casey. Other authors are Dan Farmer and Wietse Venema. They talk about various aspects of computer forensics.

Thanks much Mr. Marcelo. I will check the authors out.

I agree with Marcelo on the recommendation of Eoghan Casey. Begin your literature search with the Journal Digital Investigation.
