Serverless Security

Serverless Security is a practical 52-page PDF book from oJAYo.com. Securing functions, events and managed services in serverless applications.

Serverless computing lets developers run code without managing servers. Functions such as AWS Lambda, Azure Functions and Google Cloud Run functions start when an event arrives, run briefly and scale automatically, and you pay only for what you use. Serverless applications also rely heavily on managed services: API gateways, queues, storage and databases.

Serverless removes some security work, such as patching servers, but shifts attention to code, permissions, events and configuration. Each function is small, but an application may have hundreds of them, each with its own permissions and triggers.
