H. B. Acharya, Ph.D.'s Linkedin Analytics

I'm an engineer, researcher, and educator in Networks and Cybersecurity. I have ten years' experience creating and leading research projects, coordinating small teams, presenting reports, and teaching. Other interests: Distributed Systems, Protocols, Network Science, and Algorithms (string matching, sequence alignment, etc.) PROJECTS: 1. Data-plane network security. - The P4 language allows SDN switches to parse packets and extract header fields – but not payload fields. It's "not for DPI". Or is it? We built DeeP4R, a system that actually *does* perform DPI on P4. We currently have a limited next-gen firewall, and aim to explore intrusion detection, DNS server, and other use cases. 2. Internet Security. - Do network outages and censors affect users *in other countries*? Can we route around them using overlays or CDN? Or, in the worst case (no disruption-free paths), can we "punch through" the blockage? Our Decoy Routing system, SiegeBreaker, is one way to do this. 3. Meshed Tree Protocol. - In Data Centers etc., we no longer compute loop-free paths or multi-paths at L2; it is all done in L3. *Can* a fast, resilient network backplane at L2 outperform L3 solutions? SKILLS: 1. Communication – Ten years of experience in teaching, presentation, and technical and non-technical writing. Ratings of 4.5+/ 5 as a teacher. 2. CyberSecurity – Research experience in Firewalls, Intrusion Detection, Internet Security (BGP, DNS). Five years of experience teaching skills (VM lab, firewall/proxy, flow tools, Snort/Zeek, VPN etc.) 3. Networks – Research experience with SDN, Internet Measurement, and Protocols. Five years of experience teaching skills (Wireshark/Scapy, Traceroute, Layer-2/Layer-3/overlay networks, software-defined and data-center networks etc.)
