Amazon DynamoDB Streams now supports attribute-based access control (ABAC), enabling you to use tag-based conditions in your Identity and Access Management (IAM) policies to control access to your data streams. ABAC is an authorization strategy that simplifies access management by allowing you to enforce different access levels for multiple teams and applications using fewer IAM policies. This capability is built for teams that manage DynamoDB Streams access across multiple applications and environments and need finer-grained, scalable access control.
