The only thing I did was the CWA Certification for 99$.
I'm looking forward for the next level certs, CWE and CWP.
The CWA is a very good entry level cert for whit hat hackers and is (in my point of view) already better then the CEH by EC-Counsil.
I'm really looking forward for the next ones because these will be also practical, so you really have to hack a system (CTF kinda thing I suppose). The CWE should be available around June this year.
I haven't heard about the 24/hr access yet. What exactly is that?
