When I first began working with serverless architectures in 2018, I quickly discovered that my traditional security playbook wasn’t going to cut it. The ephemeral nature of functions, the distributed service architecture, and the multiplicity of entry points created a fundamentally different security landscape.
After several years of implementing IAM strategies for serverless applications across various industries, I’ve compiled the approaches that have proven most effective in real-world scenarios. This article shares these insights, focusing on practical Python implementations that address the unique security challenges of serverless environments.
