Overview: Cloud Penetration Testing

Quick Definition

Cloud penetration testing is a security assessment process that evaluates the vulnerabilities and weaknesses within cloud computing environments. This specialized form of penetration testing adapts traditional security testing methodologies to address the unique challenges and architecture of cloud infrastructures, including public, private, and hybrid cloud deployments.

Unlike conventional network penetration testing, cloud penetration testing must account for shared responsibility models, where security duties are divided between cloud service providers and customers. Testers examine cloud-specific attack vectors such as misconfigured storage buckets, inadequate identity and access management (IAM) policies, insecure APIs, and vulnerabilities in containerized applications or serverless functions.

The testing process typically involves reconnaissance of cloud assets, identification of misconfigurations, assessment of data encryption practices, and evaluation of network segmentation within the cloud environment. Testers also examine compliance with cloud security frameworks and industry standards.

Cloud penetration testing requires specialized tools and expertise, as traditional on-premises testing tools may not be suitable for cloud environments. Additionally, testers must coordinate with cloud service providers to ensure testing activities comply with acceptable use policies and don't impact other tenants in multi-tenant environments.
