Yêu cầu bằng cấp thực tế (Reality Check)
- Entry Level: Nhiều JD yêu cầu **Bachelor's Degree (IT/CS/Cyber)** + **Security+** (hoặc đang học). Một số nhận Associate Degree + Cert + Portfolio (Home Lab, CTF, Writeup, GitHub).
- Mid/Senior: **Kinh nghiệm thực tế (Hands-on) quan trọng hơn bằng cấp**. Bằng Thạc sĩ (MS Cybersecurity, MS CS, MBA) giúp thăng tiến Management/Architect.
- Không có bằng Đại học? Vẫn có thể vào nghề qua: **Bootcamp uy tín (SANS, Flatiron, Springboard, TCM)** + **Cert stack mạnh (Security+ → CySA+ → OSCP/PCNSE/Cloud Spec)** + **Portfolio GitHub/Blog/CTF** + **Networking (LinkedIn, Discord, Conference, Meetup)**. Khó hơn, lâu hơn, nhưng có thật.
