MTech or Phd Or Something else????

Hi,

I have done my Bachelors in Computer Applications and then did my Masters in Computer Application through Distance. I don’t want to stop here but want to do specialization in Network Security. Could you please suggest a good Masters/Phd Degree in my domain ?

Also, just to give you better picture, I am already working as a Network Engineer and my core domain is VPN security. I have already started my preparations for Juniper SSL and FW Certifications. I consider all these to be at professional end but I also want to gain a Higher Degree.

Thanks a ton.

Srini.
