Network Security Research Group (NSRG) is a group of passionate researchers working in network-based security. We investigate various network security issues such as the detection of zero-day attacks, detection of botnets, profiling Voice over IP (VoIP)  users to detect spam, detection of application layer tunnels, network traffic classification, security issues in IoT communications, malware analysis, and many more.  Following are the team members (other than me) in the NSRG:
