Route 53 Health Check Suboptimal

What this rule checks

Detects Route 53 health checks using HTTP instead of HTTPS or the standard request interval.

How to fix it

1. 1Use HTTPS to validate certificate and endpoint security
2. 2Use a 10-second request interval for critical endpoints

import * as route53 from 'aws-cdk-lib/aws-route53';

new route53.CfnHealthCheck(this, 'Hc', {
  healthCheckConfig: { type: 'HTTP', fullyQualifiedDomainName: 'example.com', port: 80 },
});

import * as route53 from 'aws-cdk-lib/aws-route53';

new route53.CfnHealthCheck(this, 'Hc', {
  healthCheckConfig: { type: 'HTTPS', fullyQualifiedDomainName: 'example.com', port: 443, requestInterval: 10 },
});

CDK Insights pinpoints the exact file and line in your CDK source for every finding, so you can jump straight to the fix.

Intentional? Suppress this finding

Sometimes a flag is deliberate — a genuinely public endpoint, say. You can dismiss route53-health-check-suboptimal and the reason is kept in the report, not silently hidden.

In .cdk-insights.json:

{
  "ignoreRules": [
    { "id": "route53-health-check-suboptimal", "reason": "Why this is intentional" }
  ]
}

Or inline in your CDK code:

Validations.of(scope).acknowledge({
  id: 'cdk-insights::route53-health-check-suboptimal',
  reason: 'Why this is intentional',
});

Use the rule ID route53-health-check-suboptimal shown above — not the CDK-* ID from SARIF / GitHub code scanning. To dismiss every finding on one construct instead, use ignorePaths. Suppression docs →
