Summary:<\/strong>\u00a0<\/span><\/h2>\n

Serverless computing, and its core compute model Function-as-a-Service (FaaS), represents a paradigm shift in application development, abstracting infrastructure management and enabling event-driven, auto-scaling architectures.<\/span>1<\/span> FaaS platforms\u2014such as AWS Lambda, Azure Functions, and Google Cloud Functions\u2014allow developers to focus solely on writing application logic that runs in response to events, while the cloud service provider (CSP) handles all server provisioning, management, and scaling.<\/span>3<\/span><\/p>\n

This abstraction, however, does not eliminate security risk; it fundamentally transforms it. The traditional security model, focused on network perimeters and host-level hardening, becomes obsolete.<\/span>5<\/span> Security responsibility shifts entirely to the domains of application code, data, and, most critically, identity and access management.<\/span>6<\/span> This new model introduces a class of FaaS-native vulnerabilities that are more abstract, harder to detect, and intrinsically linked to the event-driven, ephemeral nature of the platform.<\/span><\/p>\n

This report provides a technical analysis of the unique security challenges in FaaS architectures. It deconstructs the event-driven attack surface, examines vulnerabilities arising from the “cold start” mechanism and state management, and details the systemic architectural flaws that define the serverless threat landscape.<\/span><\/p>\n

The New Perimeter: Redefining Shared Responsibility in FaaS<\/b><\/h2>\n

Understanding FaaS security begins with the shared responsibility model, which is radically different from that of traditional Infrastructure-as-a-Service (IaaS).<\/span>8<\/span><\/p>\n

The FaaS Responsibility Model<\/b><\/h3>\n

In any cloud model, the CSP is responsible for “security <\/span>of<\/span><\/i> the cloud,” protecting the global hardware, network, and facilities that run all services.<\/span>9<\/span> The customer is responsible for “security <\/span>in<\/span><\/i> the cloud,” managing their data, configurations, and access controls.<\/span>7<\/span><\/p>\n

In a FaaS model, the CSP’s responsibility is significantly expanded. The provider manages:<\/span><\/p>\n
