On May 16, 2026, ISFnet (Headquarters: Minato-ku, Tokyo; President: Takayoshi Watanabe) provided a guest lecturer for a free seminar titled "[Understand the Latest Vulnerabilities!!] Microsoft Monthly Vulnerability Study Session," hosted by the practical security school 'Secujuku,' operated by Heatwave Co., Ltd.

### Background and Results As cyberattacks grow more sophisticated, security knowledge has become indispensable in the IT infrastructure sector. This study session aimed to teach infrastructure engineers and security personnel 'how to truly identify vulnerabilities required in the field.'

With 15 in-person attendees and 84 joining online, the event was a great success, drawing 99 participants in total. Koji Nonoshita from ISFnet's Technical Education Department presented on the latest updates regarding vulnerabilities released in the previous month and practical approaches to Microsoft's security measures. He emphasized that instead of relying solely on vendor 'severity' or CVSS scores, one must comprehensively judge factors such as exploitability to assess the true impact on the organization. This provided attendees with practical knowledge to accelerate professional development and reduce the workload in their daily operations.

### Participant Feedback In the post-seminar survey, the majority of participants rated the session as 'highly satisfied' or 'satisfied.' The Q&A session featured practical inquiries regarding AI utilization for listing and summarizing vulnerability information, highlighting the keen interest among attendees.

Key feedback included: - "I used to apply patches mechanically without proper scrutiny. This has inspired me to properly understand Microsoft security information before applying patches." - "I used to only check if information existed without checking details. I now intend to check Microsoft's vulnerability information every month." - "I would like this to be held monthly."

### Future Outlook Following this success and positive feedback, ISFnet intends to further disseminate practical security know-how developed through its own operations. By continuing such initiatives, the company aims to contribute to the training of practical security personnel and improve the overall safety of IT infrastructure in society.
