Steelin's ENZ-Engineering Zero Blog

Hello, I am Seongjin Kim (Steelin), a Cloud Security Engineer.
I follow the principle "Protect to the extent of your knowledge" and I’m constantly striving to become a top information security expert through diverse experiences.
Building on this mindset, I started my career as a security consultant and have consistently worked to broaden my knowledge in information security and cloud infrastructure.
I am now responsible for infrastructure security at a cloud service provider.
Recently, I have developed a strong interest in enhancing security for AI infrastructure and implementing Zero Trust strategies in cloud environments.
