About
My AI and Cybersecurity Learning Journey.
Welcome to CyberLens. I’m Abdurahim Yongho, a student at Metropolitan State University studying Cybersecurity and Intelligence and Security Analysis. This blog documents my learning in CYBR 325: Fundamentals of AI and ML in Cybersecurity. Each week, I explore a relevant resource, connect its ideas to course concepts, and reflect on how AI and machine learning are changing cybersecurity.
