Hi all,
I was looking to find out your opinion on attempting the GSEC without taking the related SANS training?  Reason, it's a lot of $ to get that training and my employer wants at least 3 of my kidneys to send me as it's not a requirement for my job.  I passed the CISSP earlier this year via self study and previous work experience, was wondering if I could do the same for GSEC.
If so, what books/websites?
If not, anyone got any extra kidneys I can borrow? 

Thanks,
