Security Hub controls for Route 53
These AWS Security Hub controls evaluate the Amazon Route 53 service and resources.
These controls may not be available in all AWS Regions. For more information, see Availability of controls by Region.
[Route53.1] Route 53 health checks should be tagged
Category: Identify > Inventory > Tagging
Severity: Low
Resource type:
AWS::Route53::HealthCheck
AWS Config rule:tagged-route53-healthcheck (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 Route 53 health check has tags with the specific keys defined in the parameter
requiredTagKeys. The control fails if the health check 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 health check 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 Route 53 health check, see Naming and tagging health checks in the Amazon Route 53 Developer Guide.

Category: Identify > Logging
Severity: Medium
Resource type:
AWS::Route53::HostedZone
AWS Config rule:
route53-query-logging-enabled
Schedule type: Change triggered
Parameters: None
This control checks if DNS query logging is enabled for an Amazon Route 53 public hosted zone. The control fails if DNS query logging isn't enabled for a Route 53 public hosted zone.
Logging DNS queries for a Route 53 hosted zone addresses DNS security and compliance requirements and grants visibility.
The logs include information such as the domain or subdomain that was queried, the date and time of the query, the DNS record type
(for example, A or AAAA), and the DNS response code (for example, NoError or ServFail). When DNS query
logging is enabled, Route 53 publishes the log files to Amazon CloudWatch Logs.
Remediation
To log DNS queries for Route 53 public hosted zones, see Configuring logging for DNS queries in the Amazon Route 53 Developer Guide.
