This is useful in my security work.

Please tell us why you chose Kisarazu National College of Technology

Since I lived in Chiba, I chose Kisarazu National College of Technology because it was a place where I could study computers professionally.
I didn't have many opportunities to do so, but I found it interesting to work with computers, and I wanted to learn more about what they could do, so I became interested in control engineering and information engineering.

Did you have any experience using a computer before junior high school?

The first time I used a computer was in an elementary school class where we were just trying to use the Internet. I only knew the word "programming" until junior high school, but I didn't know what it actually meant until I entered technical college.

Did you have any memorable information classes during your studies?

When I took my first programming class in my first year, I was left with an impression that I learned that programming was all about writing using a language.
Programming is interesting, but difficult, and at first I struggled to keep up with the classes. It wasn't until I was in third grade that I was able to write fluently.

Please tell us about your experience of participating in K-SEC events.

I participated in Sekucon* held in Kochi. Other things that left a lasting impression on me were learning the basics of reverse engineering from a company employee and touring a SOC.

A major factor in my introduction to the security field was attending a lecture given by then-President Hidehiko Tanaka of the Information Security Graduate University during my fourth year.

What was your graduation research like?

In the main course, we researched the strength of passwords, and in the major course, we researched the psychology of falling for spam emails.

Please tell me why you chose your current career path.

First, I listened to a lecture given by the professor at the Information Security Graduate University mentioned earlier, and I wanted to learn more about security there, so I decided to go to university.
After entering my major, I entered the Information Security Graduate University, which I had wanted to attend since my fifth year, as there was a scholarship system.
Regarding employment, I chose my current job because I was aware of SOC as a security job where I could put my knowledge to use.

Please tell us about your current job content.

My main job now is to monitor communications flowing through the network and the behavior of terminals, and analyze alerts that come up when something goes wrong to see if they are being compromised. A separate team handles customer support, so the analysis team starts by looking at communication behavior and analyzing whether it is malicious or normal.
Most of the attacks are not malicious, but in rare cases where a particular attack method is popular, we gain knowledge from the news and use it for analysis.

Has your experience as a student been useful in your current job?

I gained the basic computer knowledge necessary for working in security through the information engineering department at a technical college, and I feel that it has been useful.
I think participating in Sekyucon was also a good opportunity for me to learn. At the K-SEC event, it was very valuable and refreshing to have the opportunity to receive lectures and lectures from people from companies who are actually working in the outside world.

At the Information Security Graduate University, all classes and research are security-related, so I think I was able to learn a wide range of topics, including not only security technology, but also cryptography, law, management, and more. At graduate school, many of the students were working adults, so I learned a lot from them, such as getting used to speaking in front of people and giving me information about the industry.

Please tell us your future goals.

First of all, since I am currently experiencing SOC, I would like to be able to perform more advanced analysis than I am currently able to do.
Also, when I was choosing a career, I was torn between penetrating testing, so I would like to gain some experience in that field before deciding which one to pursue.

Please give a message to your juniors.

I think I learned enough basic things at a technical college, so I think it's important to first find a field that interests me and then deepen that field.
Security is a wide field, so I hope you find something that fits you.
