Lambda function URL needs no authentication
HIGHWhat's the problem
The function URL uses AuthType NONE. The finding says whether the resource policy (lambda:GetPolicy) already lets anyone invoke it; every call is billed to you
How 6WAF detects it
- Deterministic checks through AWS API calls (IAM, S3, EC2/VPC, CloudTrail, KMS, Secrets Manager, ACM, detection services) — no LLM is used for detection; severity is the value the scanner assigns, shown above.
- Scanning uses an IAM Role you deploy yourself via CloudFormation; 6WAF stores no credentials and you revoke access any time by deleting the stack.
- Automated scoring covers only part of the scope of standards such as ISO 27001 — this is a technical assessment, not a certification.
Pillar: Security — Fast Scan
Group: Network (Security Groups, VPC, public endpoints)
Reference standard: 6WAF classification (Lambda.1 covers public function policies)
