Security Best Practices for Kinesis Data Streams
Amazon Kinesis Data Streams provides a number of security features to consider as you develop and implement your own security policies. The following best practices are general guidelines and don’t represent a complete security solution. Because these best practices might not be appropriate or sufficient for your environment, treat them as helpful considerations rather than prescriptions.
Implement least privilege access
When granting permissions, you decide who is getting what permissions to which Kinesis Data Streams resources. You enable specific actions that you want to allow on those resources. Therefore you should grant only the permissions that are required to perform a task. Implementing least privilege access is fundamental in reducing security risk and the impact that could result from errors or malicious intent.
Use IAM roles
Producer and client applications must have valid credentials to access Kinesis data streams. You should not store AWS credentials directly in a client application or in an Amazon S3 bucket. These are long-term credentials that are not automatically rotated and could have a significant business impact if they are compromised.
Instead, you should use an IAM role to manage temporary credentials for your producer and client applications to access Kinesis data streams. When you use a role, you don't have to use long-term credentials (such as a user name and password or access keys) to access other resources.

Implement Server-Side Encryption in Dependent Resources
Data at rest and data in transit can be encrypted in Kinesis Data Streams. For more information, see Data Protection in Amazon Kinesis Data Streams.
Use CloudTrail to Monitor API Calls
Kinesis Data Streams is integrated with AWS CloudTrail, a service that provides a record of actions taken by a user, role, or an AWS service in Kinesis Data Streams.
Using the information collected by CloudTrail, you can determine the request that was made to Kinesis Data Streams, the IP address from which the request was made, who made the request, when it was made, and additional details.
For more information, see Logging Amazon Kinesis Data Streams API Calls with AWS CloudTrail.
