Wireshark Case Studies [Data Network, System & Security] Jan 2019 – May 2019 Involved in several Wireshark oriented case studies, with focus on TCP, and learned Packet Sniffing. Simulated and verified that TELNET, FTP & HTTP are not secure during data transmission. Also, simulated & verified SSH (using PUTTY) was encrypted & secure while data transmission (Login using Username & password). Involved in examining Trouble-shooting Wi-Fi Problems-customer getting disconnected again & again, Diagnosing pre-collected Trace to resolve the issue of servers taking too long to transfer ~300 GB Data (Issue zeroed using Delta time & Window Scaling) Used variety of Wireshark filters to remove noise, follow TCP stream & searching specific packets based on protocols.

octoScope WiFi-Testing [ Wireless Communication Systems Lab] Jan 2019 - April 2019 Weekly project involves introduction to oscilloscopes, octoScope Testbed for WiFi oriented experiments to gather observations like– RateVsRange (RvR), RvR Versus Orientation, Rate Versus Orientation Versus Range. Used STAPal to gather observations like Throughput, RSSI, Rx/Tx MCS, Rx/Tx Data Rate for MIMO. For OFDMA, observed the latency of signal with alternative configurations. Also exposed to the working of Synchrosniffer while taking observations for OFDMA. Malware Traffic Analysis [Cryptography & Data Security] Jan 2018 – May 2018 Exploited a given trace to find the Indicators of Compromise including IP address, Domain Name, User Agent, Host Name, File Hashes, Specific pattern using Wireshark & “totalvirus” portal.
