Abstract

Keio is a leading research university where 33,436 students are currently registered with 3,140 faculty members. The university system was cracked in September 2020 by malicious crackers where it is composed of the internet-connected-integrated database across the administrative and academic units. The cracked system was completely down, so that all courses from October 1 to October 7 in 2020 were canceled except my courses. The minimum survival system using private mail servers functioned, and my online courses were successfully held. This article shows my story of how to build a resilient secured education system for online lectures against malicious attacks during the pandemic.

摘要

庆应义塾是一所领先的研究型大学，目前在校学生 33,436 名，教职员工 3,140 名。该大学系统于 2020 年 9 月被恶意破解者破解，该系统由跨行政和学术单位的联网集成数据库组成。破解系统彻底宕机，以至于2020年10月1日到10月7日的所有课程都取消了，除了我的课程。使用私人邮件服务器的最低生存系统运行，我的在线课程成功举办。这篇文章展示了我在大流行期间如何为在线讲座构建一个有弹性的安全教育系统以抵御恶意攻击的故事。
