I'm particles (素粒子).

I'm a human person who lives in Tokyo and plays maimai でらっくす.

I also have a neat-ish about page at particles.moe.

Perhaps some particles move backward in time; perhaps the future affects the past in some way we don’t understand; or perhaps the universe is simply more aware than we are. — Phillip Pullman, in Lyra’s Oxford

It is the case that people have asked what my MBTI is on a semi-regular basis, and it's INTP.

I started “working” “in information security” in high school, in the United States CyberPatriot program, fka., “High School CCDC”, a cyber defense program. In truth, I spent most of my time in high school teaching threat modeling, hardening, etc to other classmates. In CyberPatriot 6, my team made it to the national finals. In college, I ran a side business producing practice materials, including vulnerable systems, patching guides, lectures, and other content, across all major operating systems. I was a formal technical mentor to teams for several years.

In my career, I've implemented ISO/IEC 27001:2013 and transitioned to ISO/IEC 27001:2022, implemented ISO/IEC 27701:2019, and worked on implementing SOC 2 Type 1 & SOC 2 Type 2, in addition to technical, architectural, and organizational guidance on information security from software design to networking to organization, including all aspects of risk management and treatment.
