What is Cloud Pentesting?
Cloud Penetration Testing replicates actual cyberattacks on cloud-native services and applications, corporate components, APIs, and the cloud infrastructure of an organization. Federated login systems, serverless computing platforms, and Infrastructure as Code (IaC) are examples of this. In addition, cloud pen testing is an innovative approach developed to tackle the risks, weaknesses, and threats related to cloud infrastructure and cloud-native services.
The primary objective of cloud security testing is to protect digital infrastructure from a constantly evolving variety of threats. Additionally, it provides enterprises with the highest level of IT security assurance which is necessary to meet their risk requirements.
Benefits of Cloud Pentesting
Cloud pentesting helps enterprises that store crucial data on the cloud along with cloud service providers. A majority of cloud providers have implemented a shared responsibility model between themselves and their clients.
Identify Weak Points
Testing for cloud penetration guarantees that vulnerabilities are quickly fixed once they are found. The thorough scanners can detect even the smallest weaknesses before hackers take use of them.
Improve Security
The continuous update of security mechanisms is another advantage. If any security holes are discovered in existing security mechanisms, it helps improve them.
Enhance Reliability
Frequent execution of pen tests on cloud infrastructure might enhance the dependability and credibility attributed to cloud service providers.
Preserve Compliance
Conducting cloud pen tests is beneficial in identifying areas of non-compliance with different regulatory standards and vulnerabilities.
Our Testing Methodology
The following steps must be taken when conducting Cloud pen testing, ensuring comprehensive security assessment.
1. Information Gathering
Information gathering is the first step in cloud penetration testing. Here is where the penetration testing team can obtain important documents from the organization. They employ several techniques and instruments together with the data to fully utilize the technical insights.
2. Planning
The pen testers established their objectives and aims by delving deeply into the web application's complex technicalities and abilities. The testers adapt their strategy and study to target certain vulnerabilities and malware within the application.
3. Automation Scanning
Here, automated cloud-based pen testing tools are utilized to scan for surface-level vulnerabilities and expose them before an actual hacker does.
4. Manual Testing
In this step, pen testers manually navigate the application and execute tests to eliminate the weaknesses discovered.
5. Reporting
During this phase, pen testers create a comprehensive and developer-friendly report that includes every detail about the vulnerability discovered and how to address it.
6. Retest
During this step, testers re-test the application to see whether any issues remain after the developer's remediation.
Common Cloud Vulnerabilities
Here are some of the most common vulnerabilities among the many attack methods that may result in different kinds of damaging incidents of your cloud Security services.
Insecure Coding Techniques
Most companies try to develop their cloud infrastructure as cheaply as possible. Because of poor development practices, such software often has issues such as SQL, XSS, and CSRF. Furthermore, these vulnerabilities are at the root of most cloud web service intrusions.
Out-of-date Software
Outdated software contains serious security weaknesses that may harm your cloud penetration testing services. As a result, numerous cloud services relying on old software are prone to vulnerability.
Insecure APIs
APIs are commonly used in cloud services to transfer data across different applications. However, unsecured APIs can cause large-scale data leaks. Improper use of HTTP methods might allow hackers to transfer malware or erase data from your server.
Weak Credentials
Using popular or weak passwords leaves your cloud accounts vulnerable to hacking attempts. The attacker can utilize automated programs to make guesses, gaining access to your account using that login information. The consequences could be harmful resulting in a full account takeover.
Frequently Asked Questions
Everything you need to know about cloud penetration testing.
The Shared Responsibility Model defines which security tasks belong to the cloud provider and which belong to you. AWS, Azure, and GCP are responsible for the physical hardware, hypervisor, and core infrastructure — the 'security of the cloud'. You are responsible for everything running on top: IAM policies, network security groups, application code, data encryption settings, and access controls — the 'security in the cloud'. iSecNet tests everything within your responsibility boundary: IAM misconfigurations, storage access policies, network segmentation, compute security, API exposure, and application-layer vulnerabilities. We operate within each provider's official penetration testing policy.
In traditional networks, lateral movement means an attacker pivots from one server to neighbouring systems. In cloud environments, it is far more powerful because cloud services are interconnected through IAM permissions. A compromised EC2 instance with an overly permissive role can call AWS API actions — reading from S3 buckets, launching new instances, accessing Secrets Manager, or assuming other IAM roles — without ever touching the network. An attacker who compromises a single Lambda function or misconfigured API Gateway endpoint can potentially escalate to full account administrator access without any traditional network movement. iSecNet specifically tests cross-service IAM permission chains and simulates cloud-native lateral movement paths.
Yes — and this is one of the highest-priority checks in any cloud pentest. Misconfigured cloud storage is responsible for some of the largest data breaches in history. iSecNet tests for: publicly accessible buckets or blobs, bucket policies that allow unauthenticated access, overly permissive ACLs on individual objects, bucket enumeration from public SSL certificates and DNS records, server-side encryption not enabled on sensitive buckets, bucket versioning and logging disabled, and cross-account access policies broader than intended. We test from both an external unauthenticated position and from within the account with read-only credentials to identify internal misconfiguration patterns.
Server-Side Request Forgery (SSRF) occurs when an attacker can make your server make HTTP requests to internal endpoints. In cloud environments it is catastrophic: every AWS EC2 instance, ECS container, and Lambda function has access to a metadata endpoint at 169.254.169.254 (IMDSv1) that returns the instance's IAM credentials in plain text. An SSRF vulnerability in any cloud-hosted application can be chained directly to steal IAM credentials and access all cloud resources the role permits. iSecNet tests every URL input, image fetch, webhook, and redirect for SSRF, and verifies whether your cloud environment uses IMDSv2 (the secure version requiring a multi-step request) or the vulnerable IMDSv1.
Yes — Kubernetes is one of the most complex and commonly misconfigured components of modern cloud infrastructure. iSecNet's Kubernetes security testing covers: RBAC misconfiguration (can a service account in one namespace access resources in another?), exposed Kubernetes dashboard without authentication, container escape vulnerabilities, privileged container abuse, unsecured kubelet API endpoints, secrets stored in environment variables instead of Kubernetes Secrets or external secret managers, and network policy gaps allowing lateral movement between pods. Managed Kubernetes services (EKS, AKS, GKE) have their own provider-specific misconfigurations we test separately from the Kubernetes layer itself.
Yes — serverless functions introduce a distinct set of vulnerabilities that traditional cloud testing misses entirely. iSecNet tests: overly permissive execution roles, injection vulnerabilities triggered via event sources (S3 events, SQS messages, API Gateway), insecure deserialization of event payloads, secrets hardcoded in environment variables, function URL access control, cold-start information disclosure in error messages, and event source injection — can an attacker craft an S3 object name or SQS message that triggers malicious code execution in your function? Serverless architecture is not inherently more secure — it simply shifts the attack surface from infrastructure to function code and IAM.
