Controlling Access to Kinesis Video Streams with WebRTC Resources Using Amazon Identity and Access Management - Kinesis Video Streams
Services or capabilities described in Amazon Web Services documentation might vary by Region. To see the differences applicable to the China Regions, see Getting Started with Amazon Web Services in China (PDF).

Controlling Access to Kinesis Video Streams with WebRTC Resources Using Amazon Identity and Access Management

By using Amazon Identity and Access Management (IAM) with Amazon Kinesis Video Streams with WebRTC, you can control whether users in your organization can perform a task using specific Kinesis Video Streams with WebRTC API operations and whether they can use specific Amazon resources.

For more information about IAM, see the following:

Policy Syntax

An IAM policy is a JSON document that consists of one or more statements. Each statement is structured as follows:

{ "Statement":[{ "Effect":"effect", "Action":"action", "Resource":"arn", "Condition":{ "condition":{ "key":"value" } } } ] }

There are various elements that make up a statement:

  • Effect: The effect can be Allow or Deny. By default, IAM users don't have permission to use resources and API actions, so all requests are denied. An explicit allow overrides the default. An explicit deny overrides any allows.

  • Action: The action is the specific API action for which you are granting or denying permission.

  • Resource: The resource that's affected by the action. To specify a resource in the statement, you need to use its Amazon Resource Name (ARN).

  • Condition: Conditions are optional. They can be used to control when your policy is in effect.

As you create and manage IAM policies, you might want to use the IAM Policy Generator and the IAM Policy Simulator.

Actions for Kinesis Video Streams with WebRTC

In an IAM policy statement, you can specify any API action from any service that supports IAM. For Kinesis Video Streams with WebRTC, use the following prefix with the name of the API action: kinesisvideo:. For example: kinesisvideo:CreateSignalingChannel, kinesisvideo:ListSignalingChannels, and kinesisvideo:DescribeSignalingChannel.

To specify multiple actions in a single statement, separate them with commas as follows:

"Action": ["kinesisvideo:action1", "kinesisvideo:action2"]

You can also specify multiple actions using wildcards. For example, you can specify all actions whose name begins with the word "Get" as follows:

"Action": "kinesisvideo:Get*"

To specify all Kinesis Video Streams operations, use the asterisk (*) wildcard as follows:

"Action": "kinesisvideo:*"

For the complete list of Kinesis Video Streams API actions, see the Kinesis Video Streams API reference.

Amazon Resource Names (ARNs) for Kinesis Video Streams

Each IAM policy statement applies to the resources that you specify using their ARNs.

Use the following ARN resource format for Kinesis Video Streams:

arn:aws:kinesisvideo:region:account-id:channel/channel-name/code

For example:

"Resource": arn:aws:kinesisvideo::*:111122223333:channel/my-channel/0123456789012

You can get the ARN of a channel using DescribeSignalingChannel.

Granting Other IAM Accounts Access to a Kinesis Video Stream

You might need to grant permission to other IAM accounts to perform operations on Kinesis Video Streams with WebRTC signaling channels. A service role is an IAM role that a service assumes to perform actions on your behalf. An IAM administrator can create, modify, and delete a service role from within IAM. For more information, see Creating a role to delegate permissions to an Amazon Web Service in the IAM User Guide.

Example Policies for Kinesis Video Streams with WebRTC

The following example policies demonstrate how you can control user access to your Kinesis Video Streams with WebRTC channels.

Example 1: Allow users to get data from any signaling channel

This policy allows a user or group to perform the DescribeSignalingChannel, GetSignalingChannelEndpoint, ListSignalingChannels, and ListTagsForResource operations on any signaling channel.

{ "Version": "2012-10-17", "Statement": [ { "Effect": "Allow", "Action": [ "kinesisvideo:Describe*", "kinesisvideo:Get*", "kinesisvideo:List*" ], "Resource": "*" } ] }
Example 2: Allow a user to create a signaling channel

This policy allows a user or group to perform the CreateSignalingChannel operation.

{ "Statement": [ { "Effect": "Allow", "Action": [ "kinesisvideo:CreateSignalingChannel" ], "Resource": "*" } ] }
Example 3: Allow a user full access to all Kinesis Video Streams and Kinesis Video Streams with WebRTC resources

This policy allows a user or group to perform any Kinesis Video Streams operation on any resource. This policy is appropriate for administrators.

{ "Version": "2012-10-17", "Statement": [ { "Effect": "Allow", "Action": "kinesisvideo:*", "Resource": "*" } ] }
Example 4: Allow a user to get data from a specific signaling channel

This policy allows a user or group to get data from a specific signaling channel.

{ "Version": "2012-10-17", "Statement": [ { "Effect": "Allow", "Action": "kinesisvideo:DescribeSignalingChannel", "Resource": "arn:aws:kinesisvideo:us-west-2:123456789012:channel/channel_name/0123456789012" } ] }
