Mengamankan AWS melibatkan berbilang lapisan — identiti dan akses (IAM), keselamatan rangkaian, perlindungan data (penyulitan), pemantauan/pengesanan, dan mematuhi model tanggungjawab bersama (shared responsibility model). Keselamatan ialah disiplin kritikal yang berterusan dan satu tonggak Well-Architected.
Model tanggungjawab bersama
AWS secures the CLOUD (infrastructure: hardware, facilities, managed service internals).
YOU secure what's IN the cloud (your data, IAM, network config, OS patching on EC2,
application security, access control).
→ Know the boundary: AWS handles infrastructure; YOU handle configuration and data.
Most breaches are CUSTOMER misconfigurations (e.g. public S3 buckets), not AWS failures.
