AWS Kinesis AccessDeniedException encountered when attempting to perform an operation on AWS Kinesis.

What is AWS Kinesis AccessDeniedException encountered when attempting to perform an operation on AWS Kinesis.

Understanding AWS Kinesis

AWS Kinesis is a platform on AWS to collect, process, and analyze real-time, streaming data. It enables developers to build real-time applications that can process or analyze streaming data for specialized needs. Kinesis is often used for log and event data collection, real-time analytics, and data ingestion into other AWS services.

Identifying the Symptom: AccessDeniedException

When working with AWS Kinesis, you might encounter the AccessDeniedException. This error typically occurs when a user attempts to perform an operation without the necessary permissions. The error message usually indicates that the user is not authorized to perform the requested action.

Understanding the AccessDeniedException

The AccessDeniedException is a common error in AWS services, including Kinesis. It signifies that the AWS Identity and Access Management (IAM) policies do not grant the user the required permissions to execute the operation. This can happen if the IAM role or user policy is missing necessary permissions or if there are explicit deny rules in place.

Common Scenarios for AccessDeniedException

Attempting to create or delete a Kinesis stream without the kinesis:CreateStream or kinesis:DeleteStream permissions.Trying to put records into a stream without kinesis:PutRecord or kinesis:PutRecords permissions.Accessing a stream without kinesis:DescribeStream permissions.

Steps to Resolve AccessDeniedException

To resolve the AccessDeniedException, follow these steps:

Step 1: Review IAM Policies

Check the IAM policies attached to the user or role attempting the operation. Ensure that the necessary permissions are included. For example, if you are trying to put records into a stream, ensure the policy includes kinesis:PutRecord or kinesis:PutRecords.

{ "Version": "2012-10-17", "Statement": [ { "Effect": "Allow", "Action": [ "kinesis:PutRecord", "kinesis:PutRecords" ], "Resource": "arn:aws:kinesis:REGION:ACCOUNT_ID:stream/STREAM_NAME" } ]}

Step 2: Verify Explicit Deny Rules

Ensure there are no explicit deny rules that might override the allow permissions. Explicit deny rules take precedence over allow rules in IAM policies.

Step 3: Use the AWS Policy Simulator

Utilize the AWS Policy Simulator to test and verify the permissions. This tool helps you understand which policies are granting or denying permissions.
