Summary
Barry Irwin is a Professor of Cyber Security with 13 years of professional experience and a multi-decade career designing and deploying large-scale networking and infosec solutions across mobile operators in Asia, Africa, Europe and Oceania. He combines academic research—holding a PhD in Information Security and published work on emerging threats—with hands-on engineering, having built custom high-availability firewall solutions and led global content delivery rollouts. His roles span university professorships and applied research at CSIR, together with consulting and systems management for education and telecom clients. Barry’s technical strengths include TCP/IP, Layer 2/3 design, Linux/FreeBSD systems administration and NGN architectures, reinforced by CISSP certification. He mentors graduate students (and humorously describes himself as a “herder of packets and Grad students”) while staying actively involved in threat intelligence and cyber range development. Based in Agder, Norway, he blends practical operator-grade deployment experience with rigorous postgraduate supervision and curriculum leadership.
