RBAC assigns privileges via roles (like IAM groups or IAM roles), while ABAC uses tags and rule engines evaluating user, resource, and environment attributes for finer-grained control. A comparison table highlights that RBAC is simpler but less scalable and granular, while ABAC is more complex but offers greater flexibility. AWS IAM tags and condition keys are pointed to as the mechanism for building ABAC policies. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### What is the difference between RBAC and ABAC access control? Role-based access control (RBAC) assigns privileges based on a user's role, such as user, manager, or administrator, making it simple to implement but limited in granularity and scalability. Attribute-based access control (ABAC) instead evaluates attributes of the user, resource, and environment through a rule engine, offering much finer-grained and more scalable access control at the cost of implementation complexity. _Comparing access control models like RBAC and ABAC before choosing one is easier with daily.dev's developer community insights._ ### How do you implement attribute-based access control (ABAC) in AWS IAM? AWS IAM supports ABAC by letting you attach tags to IAM entities, such as users or roles, and to AWS resources like S3 buckets. You then define policies using tag condition keys that grant permissions based on matching attributes between the principal and resource, enabling fine-grained rules such as restricting access by age or geo-location that would be hard to maintain with RBAC alone. _Developers designing fine-grained IAM policies can find practical AWS access control guidance on daily.dev._ ## Similar posts on daily.dev - [RBAC vs ReBAC: Comparing Role-Based & Relationship-Based Access Control](https://daily.dev/posts/rbac-vs-rebac-comparing-role-based-relationship-based-access-control-a4hkfzjx5) · Security Boulevard · 0 upvotes · 0 comments - [How Attribute-Based Access Control Helps You Write Better Authorization Rules](https://daily.dev/posts/how-attribute-based-access-control-helps-you-write-better-authorization-rules-uk1hcwjwk) · freeCodeCamp · 1 upvotes · 0 comments - [What Is Role-Based Access Control \(RBAC\)?](https://daily.dev/posts/what-is-role-based-access-control-rbac--ofppjlkdu) · Nordic APIs · 0 upvotes · 0 comments - [Introducing attribute-based access control for Amazon S3 general purpose buckets](https://daily.dev/posts/introducing-attribute-based-access-control-for-amazon-s3-general-purpose-buckets-5rdbbb8ga) · AWS · 1 upvotes · 0 comments - [The Essential Guide to Access Control](https://daily.dev/posts/the-essential-guide-to-access-control-34kfxpgrj) · Descope · 0 upvotes · 0 comments --- Tags: [#aws](https://daily.dev/tags/aws), [#authorization](https://daily.dev/tags/authorization), [#aws-iam](https://daily.dev/tags/aws-iam) [View this post on daily.dev](https://daily.dev/posts/rbac-and-abac-with-aws-iam-lrfxdgwl6) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"RBAC and ABAC with AWS IAM","url":"https://daily.dev/posts/rbac-and-abac-with-aws-iam-lrfxdgwl6","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/rbac-and-abac-with-aws-iam-lrfxdgwl6"},"datePublished":"2026-08-23T12:21:59.016Z","dateModified":"2026-08-23T12:40:35.169Z","description":"An explainer comparing role-based access control (RBAC) and attribute-based access control (ABAC) using AWS IAM as the implementation context.
