AWS customers may conduct penetration tests on approved services without prior AWS approval, including EC2, RDS, CloudFront, API Gateway, Lambda, Fargate, and more. This permission streamlines pentesting, letting organisations focus on uncovering misconfigurations—such as overly permissive IAM policies or public S3 buckets—rather than navigating red tape . With cloud migration accelerating, robust AWS pentesting ensures that elasticity and flexibility don’t come at the cost of security.

What Is AWS Cloud Penetration Testing?

 

AWS Cloud Penetration Testing simulates real-world attacks against cloud resources (EC2, S3, IAM, Lambda, RDS, etc.) to identify vulnerabilities in configuration, network segmentation, and identity management.

In-Scope vs. Out-of-Scope

 

• In-Scope (no approval needed): EC2, RDS, API Gateway, Lambda, Elastic Beanstalk, Fargate, Lightsail, CloudFront, AppSync, Aurora, Transit Gateway .

• Out-of-Scope (approval required or prohibited): Denial-of-Service (DoS) testing, AWS-managed infrastructure (Route 53 zones), AWS service provider assets

Why Is AWS Cloud Penetration Testing Important?

 

 

1. Enforces the Shared Responsibility Model
   AWS secures “of the cloud,” while you secure “in the cloud.” Pentesting validates your controls across services like EC2 and S3.
2. Uncovers Hidden Misconfigurations
   Over-permissive IAM roles, exposed S3 buckets, misconfigured VPCs, and weak network ACLs cause most cloud breaches.
3. Meets Compliance Demands
   Regulations such as HIPAA, PCI DSS, and SOC 2 require periodic pentests. A formal AWS pentest report accelerates audit readiness.
