HOSPITAL: Host and Network System Profiler and Internet Traffic Analyzer
The ever-increasing complexity and diversity of the Internet pose several challenges to network operators and administrators and, in general, Internet users. More specifically, because of the diversity in applications and usage patterns; the prevalence of dynamic IP addresses and applications that do not conform to standard configuration (e.g. VoIP to bypass firewalls), monitoring and securing networks and end hosts is no longer a trivial task. In this paper, the authors propose Host and netwOrk System Profiler and Internet Traffic AnaLysis (HOSPITAL): a tool for the summarization, characterization of traffic and the troubleshooting of potential suspicious activities.
