The 17th Asia Joint Conference on Information Security (AsiaJCIS2022) was held online using Zoom on August 15 and 16. Oral and poster presentations were given, including security alert analysis using machine learning, information leakage countermeasures using log management, and a proposal for high-speed symmetric key cryptography for 5G/6G communications. There were also many invited lectures, and it was a meaningful meeting where participants could come into contact with practical research with an eye toward social implementation. A lively Q&A session was held via Zoom and Slack.
