AWS Penetration Testing: Scope, Rules & Checklist (with Azure)

Quick answer: AWS penetration testing is an authorized security test of your own AWS environment, focused on your side of the shared responsibility model: identities and permissions, storage, networking, compute, serverless and data services. AWS and Azure both allow customers to test their own resources within published rules, but you must stay within the permitted services and avoid denial-of-service testing.

Moving to AWS or Azure does not move the responsibility for security to the provider. The provider secures the underlying infrastructure, but you are responsible for how your accounts, identities, networks, applications and data are configured. Most cloud breaches trace back to configuration and access mistakes, not to a flaw in the provider itself.

This guide explains AWS penetration testing and its Azure equivalent: what to include in scope, which rules apply, which attack paths testers look for and how to prepare. If you want an expert assessment, see Privaxi's cloud penetration testing service, which covers AWS and Azure.

What Is AWS Penetration Testing?

AWS penetration testing is a simulated attack against the resources you run in Amazon Web Services. Testers behave like an attacker who has found a foothold, such as an exposed credential, a public storage bucket or a vulnerable web application, and then try to escalate access, move between services and reach sensitive data.

It differs from a vulnerability scan. A scan lists known issues. A cloud pen test shows how misconfigurations combine into a real attack path, for example a low-privilege role that can assume a more powerful one. We explain the wider difference in our guide to penetration testing services.

Why Cloud Penetration Testing Matters Even With Provider Security

The shared responsibility model divides security into two halves. The provider protects the hardware, facilities and core services. You protect everything you build and configure on top of them. Cloud environments change quickly, permissions accumulate and defaults are not always safe, so risk grows quietly. Cloud penetration testing tests your half of the model the way an attacker would.

Are You Allowed to Penetration Test AWS and Azure?

Yes, with limits. AWS publishes a penetration testing policy that allows customers to test certain services on their own accounts without prior approval, and Microsoft publishes rules of engagement for testing Azure resources. Both prohibit activities that harm the platform or other customers. In general you must not:

• Run denial-of-service or stress tests against cloud services without specific permission.
• Test resources that belong to other customers or to the provider.
• Attempt to break out of virtualization or access the provider's infrastructure.
• Use techniques that violate the provider's acceptable-use terms.

Policies change, so check the current AWS and Microsoft pages before testing and confirm that your provider follows them. Reputable testers agree rules of engagement, test windows and non-destructive techniques in writing before starting.

What to Include in AWS Penetration Testing Scope

Scope determines what is found. Our guide to penetration testing scope covers the principles, and for AWS the typical areas are:

• Identity and access management (IAM). Users, roles, policies, privilege escalation paths and cross-account trust.
• Storage. S3 bucket policies, public access settings and object exposure.
• Compute. EC2 instances, security groups and the instance metadata service.
• Serverless and APIs. Lambda functions, API Gateway configuration and authorization.
• Data services. RDS and other managed databases, snapshots and encryption settings.
• Organization boundaries. AWS Organizations, service control policies and account separation.
• Secrets and keys. Credentials in code repositories, environment variables and build pipelines.

Azure Penetration Testing Scope

Azure penetration testing follows the same logic with different building blocks:

• Entra ID identities. Role assignments, conditional access gaps and guest or service principal exposure.
• Storage accounts. Public access, shared access signatures and key exposure.
• Virtual machines and networking. Network security groups, public IPs and managed identities.
• App services and functions. Authentication settings and exposed endpoints.
• Key Vault. Access policies and secret exposure.
• Subscription and management group boundaries. Whether one compromised subscription can reach others.

Common Cloud Attack Paths Testers Look For

AWS Penetration Testing Methodology

1. Scoping and authorization. Define accounts, regions and services, and sign rules of engagement.
2. Reconnaissance. Enumerate public endpoints, DNS, buckets and exposed services.
3. Configuration review. Assess IAM, networking and storage settings with read-only access where provided.
4. Exploitation. Safely attempt to use weaknesses to escalate access or reach data.
5. Post-exploitation analysis. Determine how far an attacker could move and what they could access.
6. Reporting and remediation guidance. Prioritized findings with clear fixes.
7. Retesting. Verify that the fixes work.

Some engagements use grey-box testing, where the tester receives limited credentials. This often finds more because it models an attacker who has already obtained a foothold.

Cloud Penetration Testing and Compliance

Cloud assessments feed several frameworks. SOC 2, ISO 27001, PCI DSS and HIPAA audits all expect vulnerability management and evidence of testing for systems in scope. We cover those in SOC 2 penetration testing requirements and PCI DSS 11.4 penetration testing. Confirm with your assessor which cloud components fall inside your audit boundary.

How to Prepare for a Cloud Penetration Test

1. Inventory accounts and subscriptions. Include production, staging and shared services.
2. Choose the environment. Testing staging that mirrors production is safer, but production often reveals real configuration drift.
3. Set up test access. Provide read-only roles or limited credentials if you want a grey-box test.
4. Notify your team. Make sure monitoring and on-call staff know the test window.
5. Back up critical data. Confirm recovery options before testing begins.
6. Plan remediation. Decide who owns each finding and when you will retest.

Cost depends mainly on scope and depth. See how much penetration testing costs for the pricing factors, and our guide to choosing a penetration testing company for questions to ask providers.

Example Cloud Penetration Test Findings and Severity

Severity depends on context, but these examples show how common cloud findings are usually rated:

AWS and Azure Hardening Quick Wins Before You Test

Fixing the obvious items first lets the test spend its time on harder problems. Consider these before booking:

• Enable multi-factor authentication for all privileged and console users.
• Turn on account-level public access blocking for storage.
• Remove unused access keys and rotate long-lived ones.
• Require the more secure metadata service version on AWS compute instances.
• Review administrator and owner role assignments in both clouds.
• Enable audit logging, such as CloudTrail on AWS and activity logs on Azure, and send logs to a protected location.
• Restrict inbound rules on security groups and network security groups to what is truly needed.
• Scan repositories and build pipelines for secrets.

These steps also help with audits. Cloud configuration is a standard focus for SOC 2 and ISO 27001 assessments, so the work pays off twice.

Continuous Testing for Cloud Environments

Cloud environments change daily, so a single annual test can become outdated quickly. Many teams add recurring external testing between deeper engagements. Penetration testing as a service re-tests the internet-facing perimeter on a regular schedule, and our comparison of PTaaS vs traditional penetration testing explains how to combine the two.

Frequently Asked Questions

Do I need permission to penetration test AWS?

AWS allows customers to test certain services on their own accounts without prior approval, as long as they follow its penetration testing policy. Prohibited activities include denial-of-service attacks. Check the current policy before testing.

What is the difference between AWS penetration testing and a cloud security audit?

A security audit reviews configuration against a standard or best practice. A penetration test tries to exploit weaknesses to show how an attacker could actually move through your environment. The two are complementary.

What does Azure penetration testing cover?

Azure penetration testing typically covers Entra ID identities and roles, storage accounts, virtual machines and network security groups, app services and functions, Key Vault access and subscription boundaries.

How often should cloud penetration testing be done?

At least once a year and after significant changes such as new accounts, major architecture changes or new internet-facing services. Fast-changing environments often add recurring external testing.

Is cloud penetration testing safe for production?

It can be when testers agree rules of engagement, test windows and non-destructive techniques in advance, and your team is ready to monitor. Some organizations test staging first, then production.

What are the most common AWS security findings?

Over-permissive IAM roles, publicly exposed storage, exposed access keys, open security groups and unprotected metadata services are among the most common.

Final Thoughts

Good AWS penetration testing answers one question: if an attacker finds one weakness in your cloud account, how far could they get? Define scope carefully, follow the provider rules, test identities and storage first and verify your fixes.
