Nmap From an Ethical Hacker's Point of View

ddonzal notes a new tutorial that introduces Nmap from the viewpoint of an ethical hacker. (Part 1 of 2 parts is up now.) The author is Kirby Tucker, who writes: "After completing this 2 Part Series and having practiced the techniques described, one should not only be able to sit at a 'roundtable' with advanced security professionals and 'hold their own' in a discussion concerning Nmap, but also utilize this great tool in protecting their own network."
