I found this training session from Dino Dai Zovi to be very useful.

Thanks for all your advises. According to what you have mentioned it seems  CISSP would be the best option as i have just started my career. According to what i found out people here are much aware of CISSP than GSEC.So it would be CISSP first and then i will go for GSEC some time later.

I' am planning to get CISSP or GSEC . Please advise me on what would be the best certification to acquire first?.
