Background for this topic.
Amazon provides a large-scale cloud computing platform and an extensive e-commerce marketplace, both widely used across industries. Its cloud services offer infrastructure for hosting applications, storing data, and managing complex workflows, while its marketplace facilitates transactions between millions of buyers and sellers. These environments involve diverse user roles, APIs, and integrations with third-party services, creating multiple points of interaction and potential exposure.
Security risks include misconfigured cloud resources, such as storage buckets or access policies that unintentionally allow public or excessive permissions, leading to data exposure or unauthorized use. The e-commerce platform faces threats like account takeovers targeting customer or seller accounts, and fraud exploiting payment or order systems. Mitigating these risks requires strict identity and access management controls, continuous monitoring for unusual activity, and thorough validation of third-party components to prevent exploitation within Amazon’s complex ecosystem.
