AWS Penetration Testing Services

AWS environments require fundamentally different testing methodology from traditional on-premise infrastructure. The attack surface is not just exposed services, it is IAM policies, S3 bucket ACLs, EC2 instance metadata, Lambda execution roles, EKS RBAC, and the dozens of subtle interactions between AWS services that create realistic attack paths.

RedSecLabs delivers specialised AWS penetration testing aligned to AWS's own customer-side testing policy. Our testers combine deep AWS expertise (cloud architects who happen to be offensive security practitioners) with the methodology depth needed to find real attack paths in modern cloud environments.

Every engagement covers configuration review, IAM analysis, attack-path enumeration, and where in scope manual exploitation of identified weaknesses, producing remediation guidance specific to AWS services rather than generic infrastructure advice.

What is AWS penetration testing?

AWS penetration testing is the structured assessment of an AWS environment for exploitable security weaknesses. Unlike traditional pentesting which focuses on network and application exposure, AWS testing centres on cloud-specific attack surfaces: IAM policies and roles, S3 bucket configurations, EC2 instance metadata exposure, Lambda execution permissions, EKS pod-to-service-account mappings, RDS network exposure, and the cross-service interactions that create attack paths.

AWS operates a shared responsibility model. Amazon secures the cloud, customers secure their configuration within it. The overwhelming majority of cloud breaches trace to customer-side misconfiguration rather than AWS platform vulnerabilities, which is why customer-side AWS pentesting is so valuable.

What AWS testing delivers:

Comprehensive IAM analysis including privilege escalation paths

S3 bucket configuration review and accidental public exposure detection

EC2, EKS, and Lambda security configuration assessment

VPC, security group, and network ACL review

CloudTrail and detection coverage analysis

AWS-specific remediation guidance from cloud-native specialists

AWS testing should happen at least annually, with focused re-testing after major architectural changes or significant new AWS service adoption.

Why AWS testing matters

Cloud misconfiguration remains the leading cause of cloud-environment breaches, overly-permissive IAM policies enabling privilege escalation, publicly-exposed S3 buckets leaking customer data, exposed EC2 metadata services enabling credential theft, weak EKS RBAC allowing pod escapes. These are findable with proper testing.

Generic infrastructure pentesting rarely covers cloud-specific risk effectively. AWS testing requires understanding AWS services, what each service does, how it integrates with IAM, what its common misconfigurations look like, and what realistic attack paths combine multiple services. Generalist testers miss most of this.

Common AWS-specific risks:

IAM privilege escalation via policy combination weaknesses

S3 bucket misconfiguration leaking customer data publicly

EC2 instance metadata exposure enabling role credential theft

EKS RBAC weaknesses enabling cluster compromise

Lambda over-privileged execution roles

Cross-account assumed role chains enabling lateral movement

AWS environments demand AWS-specific testing, and the findings are typically among the highest-impact in any security programme.

Who needs AWS testing?

Any organisation with substantial AWS workloads benefits from regular AWS-specific testing:

Cloud-native SaaS organisations

Financial services on AWS

HealthTech and HIPAA workloads

E-commerce with AWS infrastructure

AI and ML platforms on AWS

GovTech and defence AWS workloads

Multi-account AWS organisations

Hybrid cloud organisations

Our AWS Testing Methodology

AWS-specific methodology aligned to the AWS customer testing policy, combining configuration review, IAM analysis, and active exploitation where in scope.

01

Scoping & AWS Access Setup

We agree the in-scope AWS accounts, services, and testing approach (read-only assessment, active exploitation, or both). Read-only IAM role access is established for testing.

02

Account Inventory & Mapping

Comprehensive enumeration of AWS resources across in-scope accounts, services in use, regions, account relationships, organisational structure.

03

IAM Policy Analysis

Deep analysis of IAM policies, roles, and trust relationships, looking for privilege escalation paths, overly-permissive policies, and cross-account risk.

04

Storage Security Review

S3 bucket configurations, public access settings, cross-account access, encryption posture, and accidental exposure of sensitive data.

05

Compute Security Review

EC2 instance configurations, security groups, instance metadata service exposure, EKS RBAC and pod security, Lambda execution roles.

06

Network Architecture Review

VPC configurations, network ACLs, security groups, VPC peering, transit gateways, and exposed endpoints.

07

Active Exploitation (Where In Scope)

Manual exploitation of identified weaknesses where the engagement scope allows. IAM privilege escalation, metadata service abuse, cross-service attack paths.

08

Detection Coverage Analysis

Assessment of CloudTrail, GuardDuty, Security Hub coverage, identifying detection gaps for the attack paths we identified.

Typical engagement: 5-8 days for single-account environments, 10-15 days for multi-account AWS organisations, longer for very large or complex estates.

Frequently Asked Questions

For most AWS services, no. AWS's customer testing policy (updated 2024) explicitly permits customer-side penetration testing of in-account resources without prior notification. Some exceptions apply (DNS zone walking, DoS testing, services hosted by other customers). We confirm the policy for your specific scope during scoping.

Cloud Security Posture Management (CSPM) tools (e.g. AWS Security Hub, Wiz, Prisma Cloud) provide automated configuration scanning, broad coverage of known misconfigurations. AWS pentesting adds manual investigation of attack paths, IAM privilege escalation analysis, and exploitation validation, depth where CSPM provides breadth. Most mature programmes use both.

Yes, multi-account testing is core scope. We test individual account configurations, cross-account trust relationships, AWS Organisations SCPs, and the attack paths that combine multi-account access. Multi-account engagements typically run 10-15 days depending on account count and complexity.

Yes, container platforms are core AWS testing scope. EKS testing covers RBAC, pod security, service account permissions, network policies, and container escape scenarios. ECS testing covers task IAM roles, container configurations, and orchestration security. Both require specialist methodology beyond generic container security.

Yes, we deliver cloud penetration testing across all three major clouds. Azure and GCP each have their own methodology page. The cloud-specific knowledge does not transfer cleanly between providers; we staff cloud engagements with platform specialists.

Single-account environments £8,000-£18,000; multi-account organisations £15,000-£35,000; very large or complex AWS estates £30,000-£80,000+. CREST premium 10-20%. Fixed-fee quotes within 48 hours of scoping.
