I'm a post graduate student and self taught programmer. I concentrated on Computer Networks & Operating Systems more during my undergraduate studies. I can explain usually used protocols by sniffing the traffic on wires. Operating Systems was my obsession, I know internals of Linux (read code & books).
Now I'm teaching myself Penetration testing from books that are well known to the community and practicing the same. I've no interest in getting "certification" but knowledge wise, would preparing CCNA syllabus help me "significantly" during my penetration tests?
I doubt because its "Cisco" certification. I mean its just one company that produces routers & firewalls.
