Barry Irwin started off as a Systems and Network administrator at the dawn of the millennium and tripped and fell into the security field. Finding nothing on the market that met the operational needs, he led the development and deployment of an open-source derived firewalling system in the early 2000’s for a global telecoms operator. He returned to academia and has spent the last 19 years working in academia on research in the larger information security field, often returning to his first love of packets and network traffic analysis. He has significant experience in, and a passion for training the next generation of security professionals within academia and a cross section of public and private sector industry.  His current areas of research include network traffic analysis, data visualisation, web-based malware, botnet identification and anti-phishing tools. Prior to relocating to Norway in 2019, he developed and headed a very successful information security focussed postgraduate program at Rhodes University, South Africa. He has a love of military history especially as it relates to codes, ciphers and espionage, and is a somewhat dormant rhykenologist.
