Thanks a lot for sharing the info. It was very useful. I'm very much interested in Security testing & had no idea where to start with. This doc. surely threw some light on that.
However, from the info. provided I assume that it's not going to be easy to become a Security Tester, is that true ? Further When I referred some sites it refers Sec. testing to kind of System / Network Admin job rather than a tester's job, can you explain me a bit more on that perspective, as I'm completely a functional tester ?
