serverless sounds cool for cutting costs but watch out! one big pitfall is giving too much power to IAM roles. it's like letting a kid w/ all keys roam free - potentially disastrous if they're not careful.
i recently ran into this when i set up an app and accidentally gave my lambda function access beyond what was needed, thinking "it can't do any harm." turns out that over-privileged role led to some data breaches.
so always double-check your IAM policies! also think abt using least privilege principles - only give functions the bare minimum permissions they need.
anyone else hit this issue? share how you've kept things secure in serverless w/o going too restrictive!
