Revisiting computer networking protocols by wireless sniffing on brain signal/image portals

Brain signal/image processing is of significant attention not only the physiologist carrying out analysis and probe and the clinician investigating patients but further to the biomedical engineer who is vital for acquisition, processing, and interpreting the electroencephalogram signals by designing systems and algorithms for their control. The precious, abundant materials or information in the field of brain signal/image processing is distributed in the diverse scientific, technological and physiological periodicals, magazines, journals, international conference proceedings, and also in various portals/databases. Security threats or attacks may happen for a portal using data interruption, information interception, content modification and fabrication with new data. This study interprets the protocol layering information for the captured packets, image reconstruction after sniffing the packets, and the DNS/rDNS response times for a given portal/IP address using a Wireshark open source tool. Also, the security assessment results such as OS fingerprinting and port sweeping on the remote machines are performed using Nmap open source tool. Results are analyzed on specific brain signal/image processing portals around the globe located in USA, UK, and other countries.
