About Shimori Cyber
Systems thinking backed by practical work.
Cybersecurity, Linux, infrastructure, networking, development, and automation documented through projects and technical writeups.
Kizura / Shimori Cyber
Build the system. Understand the failure. Improve the design.
Shimori Cyber is the professional record of my hands-on work across cybersecurity, systems, infrastructure, development, and automation. I use projects and writeups to show the reasoning behind the work rather than only listing tools.

How I Work
One repeatable technical loop.
The same process applies whether I am working on a Linux service, a network boundary, a website deployment, or a development system.
Test
Validate behavior, security, reliability, and assumptions.
Troubleshoot
Trace failures and understand what the system is actually doing.
Document
Preserve decisions, commands, failures, and useful lessons.
Improve
Refine the architecture so the next iteration is stronger.
Proof in Practice
Where the approach shows up.
Infrastructure / Security
Secure Home Lab
Trust boundaries, service exposure, credentials, recovery, monitoring, and documentation in a practical Linux environment.
View Case Study →Linux / Systems
Secure Linux Workstation
A workstation build focused on administration, security, tooling, repeatable configuration, and day-to-day usability.
Read Writeup →Networking / Security
Network Segmentation
Practical trust boundaries, isolation, firewall thinking, and why network structure matters to security and troubleshooting.
Read Writeup →Background
Security makes more sense when the whole system is visible.
My professional background includes communications and IT work with the Canadian Armed Forces, along with independent Linux administration, networking, infrastructure, technical troubleshooting, and software development.
That experience shaped how I approach cybersecurity. Security is connected to users, services, networks, software, operations, and recovery. Understanding those relationships is more useful than treating security as an isolated layer.
Shimori Cyber is where I continue building that capability in public through practical work, technical documentation, and case studies that can be inspected rather than simply claimed.
