Serverless Security

Serverless security addresses the unique challenges of protecting applications and data within a serverless computing architecture, operating under a shared responsibility model where the cloud provider secures the underlying infrastructure. The developer's focus shifts from securing servers to securing the application code itself, its configurations, and its permissions at a granular, function-by-function level. This involves practices such as writing secure, vulnerability-free functions to prevent injection attacks, enforcing the principle of least privilege through tightly scoped identity and access management (IAM) roles, vetting third-party dependencies, and properly configuring event triggers like API gateways to protect against unauthorized access and invocation.
