What are the security risks of serverless computing?

Serverless computing, also called Function as a Service, executes code in response to events without managing servers. Security risks include excessive function permissions where functions are granted more access than needed, insecure dependencies in third-party libraries bundled with functions, event injection where malicious input triggers unintended execution, insufficient logging making incident investigation difficult, and insecure secrets management when API keys are hardcoded in function code.
