I got my VISA for this fall 2013 on NYIT Old Westbury campus in Computer Science . But I have changed my travel plan and going to New York for 2014 spring . I also want to transfer my University to any other best university which is offering MS in NETWORK SECURITY ( not as a major , it has to be a group directly ) / CYBER SECURITY / INFORMATION SECURITY ....
my profile

UG % = 61%
IELTS=6.0 (6.0 in every section and 6.5 in speaking ) ( I can take it once again necessary if necessary )
GRE =282
Certifications= CISCO CERTIFIED INTERNETWORK EXPERT in Security vertion 4.0 (CCIE sec)

Suggest me the best universities which offer any of these programmes ,And where I can get GRADUATE ASSISTANTSHIP also .
Thank you .
