cybersecurity-architecture - Personal study & reference collection on security

项目说明

Cybersecurity Architecture & Defense Strategies

A personal study collection of security architecture, threat models, incident response playbooks, and defensi — compiled as learning material and reference.

> Note — this is a personal study & reference repository. It is learning material I maintain to study security architecture, threat modeling, and defense. It is not a service I offer, not a claim of professional penetration-testing or incident-response experience, and not a claim that I operated these systems in production. My professional focus is software engineering, AI, and solutions architecture — this repository reflects study, not offensive work performed.

O

This repository collects security patterns, threat-modeling frameworks, and infrastructure-as-code references for studying how secure systems are built and defended. Each component includes attack , detection strategies, mitigation controls, and compliance mappings.

Topics covered (for study & reference): threat modeling, security frameworks, incident response, cloud security, and defensi.
