IAM (Identity and Access Management) AWS मा को के गर्न सक्छ यो नियन्त्रण गर्छ — प्रयोगकर्ता, समूह, भूमिका, र अनुमतिहरू व्यवस्थापन गर्छ। यो AWS सुरक्षाको आधार हो: प्रत्येक कार्य IAM मार्फत अनुमोदित हुन्छ, त्यसैले यसलाई बुझ्नु आवश्यक छ।
IAM ले के व्यवस्थापन गर्छ
IAM controls AUTHENTICATION (who you are) and AUTHORIZATION (what you can do):
USERS → individual identities (people or applications) with credentials
GROUPS → collections of users (assign permissions to a group → all its users get them)
ROLES → identities ASSUMED temporarily (by users, services, or AWS resources)
— no permanent credentials; key for services/cross-account access
POLICIES → JSON documents defining PERMISSIONS (what actions on what resources)
