Security Hub controls for Kinesis
These AWS Security Hub controls evaluate the Amazon Kinesis service and resources.
These controls may not be available in all AWS Regions. For more information, see Availability of controls by Region.
[Kinesis.1] Kinesis streams should be encrypted at rest
Related requirements: NIST.800-53.r5 CA-9(1), NIST.800-53.r5 CM-3(6), NIST.800-53.r5 SC-13, NIST.800-53.r5 SC-28, NIST.800-53.r5 SC-28(1), NIST.800-53.r5 SC-7(10), NIST.800-53.r5 SI-7(6)
Category: Protect > Data Protection > Encryption of data-at-rest
Severity: Medium
Resource type:
AWS::Kinesis::Stream
AWS Config rule: kinesis-stream-encrypted
Schedule type: Change triggered
Parameters: None
This control checks if Kinesis Data Streams are encrypted at rest with server-side encryption. This control fails if a Kinesis stream is not encrypted at rest with server-side encryption.
Server-side encryption is a feature in Amazon Kinesis Data Streams that automatically encrypts data before it's at rest by using an AWS KMS key. Data is encrypted before it's written to the Kinesis stream storage layer, and decrypted after it's retrieved from storage. As a result, your data is encrypted at rest within the Amazon Kinesis Data Streams service.
Remediation
For information about enabling server-side encryption for Kinesis streams, see How do I get started with server-side encryption? in the Amazon Kinesis Developer Guide.
[Kinesis.2] Kinesis streams should be tagged
Category: Identify > Inventory > Tagging
Severity: Low
Resource type:
AWS::Kinesis::Stream
AWS Configrule: tagged-kinesis-stream (custom Security Hub rule)
Schedule type: Change triggered
Parameters:
| Parameter | Description | Type | Allowed custom values | Security Hub default value |
|---|---|---|---|---|
requiredTagKeys
|
List of non-system tag keys that the evaluated resource must contain. Tag keys are case sensitive. | StringList | List of tags that meet AWS requirements | No default value |
This control checks whether an Amazon Kinesis data stream has tags with the specific keys defined in the parameter
requiredTagKeys. The control fails if the data stream doesn’t have any tag keys or if it doesn’t have all the keys specified in the
parameter requiredTagKeys. If the parameter requiredTagKeys isn't provided, the control only checks for the existence
of a tag key and fails if the data stream isn't tagged with any key. System tags, which are automatically applied and begin with aws:,
are ignored.
A tag is a label that you assign to an AWS resource, and it consists of a key and an optional value. You can create tags to categorize resources by purpose, owner, environment, or other criteria. Tags can help you identify, organize, search for, and filter resources. Tagging also helps you track accountable resource owners for actions and notifications. When you use tagging, you can implement attribute-based access control (ABAC) as an authorization strategy, which defines permissions based on tags. You can attach tags to IAM entities (users or roles) and to AWS resources. You can create a single ABAC policy or a separate set of policies for your IAM principals. You can design these ABAC policies to allow operations when the principal's tag matches the resource tag. For more information, see What is ABAC for AWS? in the IAM User Guide.
Note
Don’t add personally identifiable information (PII) or other confidential or sensitive information in tags. Tags are accessible to many AWS services, including AWS Billing. For more tagging best practices, see Tagging your AWS resources in the AWS General Reference.
Remediation
To add tags to a Kinesis data stream, see Tagging your streams in Amazon Kinesis Data Streams in the Amazon Kinesis Developer Guide.
[Kinesis.3] Kinesis streams should have an adequate data retention period
Category: Recover > Resilience > Backups enabled
Severity: Medium
Resource type:
AWS::Kinesis::Stream
AWS Configrule: kinesis-stream-backup-retention-check
Schedule type: Change triggered
Parameters:
| Parameter | Description | Type | Allowed custom values | Security Hub default value |
|---|---|---|---|---|
minimumBackupRetentionPeriod
|
Minimum number of hours that the data should be retained. | String | 24 to 8760 | 168 |
This control checks whether an Amazon Kinesis data stream has a data retention period greater than or equal to the specified time frame. The control fails if the data retention period is less than the specified time frame. Unless you provide a custom parameter value for the data retention period, Security Hub uses a default value of 168 hours.
In Kinesis Data Streams, a data stream is an ordered sequence of data records meant to be written to and read from in real time. Data records are stored in shards in your stream temporarily. The time period from when a record is added to when it is no longer accessible is called the retention period. Kinesis Data Streams almost immediately makes records older than the new retention period inaccessible after decreasing the retention period. For example, changing the retention period from 24 hours to 48 hours means that records added to the stream 23 hours 55 minutes prior are still available after 24 hours.
Remediation
To change the backup retention period for your Kinesis Data Streams, see Change the data retention period in the Amazon Kinesis Data Streams Developer Guide.
