What is "digital forensics"? Digital forensics: Recently, it is sometimes called "digital forensics" or "electronic forensics", but legal proceedings and laws regarding electromagnetic records (digital data) in various electronic devices and recording media such as personal computers, servers, and smartphones. It is a scientific research method / technology that preserves and analyzes data so that it can be used as evidence in legal disputes.For example, when corporate information is leaked, the information necessary for investigations and trials is clarified by clarifying what was done using information processing technology, such as the intrusion route from the outside to the server and the authenticity of the mail sender. Digital forensics has become important in today's world where cyber attacks continue to increase, such as collecting information. Cyber ​​security human resource development course by Tokyo Denki University Tokyo Denki University has established the "Internationalized Cyber ​​Security Special Course" (CySec) in April 2015 to develop human resources for cyber security.This course has also been selected by the Ministry of Education, Culture, Sports, Science and Technology's "Graduate School Program for Re-learning Adults for Advanced Human Resource Development", and can be studied by motivated students and adults who want to acquire specialized knowledge.One of the courses, the Digital Forensics Course (mainly in charge: Professor Ryoichi Sasaki, Department of Information and Media Studies, Faculty of Future Science, Tokyo Denki University), which was held in September 4, is an executive officer, chief engineer, and general manager of the Legal Tech Operations Department of FRONTEO. Shusaku Nozaki was in charge of 2015 lectures out of a total of 9 lectures.15th October 5, 4 Basics of forensic work 2015th October 10, 9 Forensic work data preservation 5th November 2015, 10 Forensic work data analysis ② 16th November 9, 2015 Forensic Work Exercise (Collaboration by the instructor) 11th December 13, 10 Digital forensics method for typical subjects (2015) -Fraud accounting and e-discovery All five lectures given by Nozaki will be digital forensics. This is an important and practical content.In addition, through the entire course, you will be able to learn the concept and basic technology of digital forensics so that you can take emergency measures in the event of an incident such as personal information leakage or unauthorized intrusion, and you can appropriately collect and analyze logs in preparation for a trial. I aimed to acquire the ability to prepare the necessary materials without any legal problems.Participants were highly satisfied with the practical and highly specialized content. A total of 11 people, 20 students and 14 working adults, participated in this course.Many working people are security experts, and there were also participants from public institutions.In the questionnaire to the participants, a high degree of satisfaction of 2015 points was obtained out of 12 points. ・ I was able to learn from the basics of computer science to the latest technology. ・ The instructor is involved in practical work in each industry. It was well received that it was a top human resource and the content was easy to understand.Instructor Nozaki said, "Many of the students were enthusiastic about studying. After each lecture, there was a line in front of me, and I had an individual question and answer session for about an hour. I felt the students' high motivation and realized that the acquisition of digital forensics knowledge and skills is now a necessary situation. " From materials created by Professor Ryoichi Sasaki, Professor, Department of Information and Media Studies, Faculty of Science and Technology for Future Science, Tokyo Denki University CySec will continue to focus on training advanced cybersecurity experts in Japan, such as Chief Information Security Officers (CISOs) or senior security engineers, and will continue to focus internationally in the future. We aim to send out human resources who can play an active role. FRONTEO will continue to cooperate as an opportunity to widely convey the advanced technology and experience gained through practice.Tokyo Denki University International Cyber ​​Security Special Course https://cysec.dendai.ac.jp/ FRONTEO e Discovery & Forensics Co., Ltd. https://legal.fronteo.com/forensics/
