iamlive VS pike

Also things like this (same guy) if you have a sandbox to play in with wider permissions and are trying to build a more scoped profile: https://github.com/iann0036/iamlive

I know there is a tool called iamlive that logs all API calls on your local machine. So you can run commands as an admin user locally while this is running, and find out what permissions were needed. Then you tear down the infra you just deployed, and add those same permissions to a service user of some kind (e.g. a CICD role) to avoid over-privileging it. It's messy but it can be helpful.

actually Ian (aws hero) has a tool that does exactly this

https://github.com/iann0036/iamlive

I have used https://github.com/iann0036/iamlive with great success in the past. On high level, the approach you are describing is iamlive on steroids and UX improved.

Kudos on launch, will check your beta

Thanks! Permissions are determined per resource or datasource. There's no easy way that I had found, especially if you want this done statically, https://github.com/iann0036/iamlive does it by inspecting your api calls but there's always a look up somewhere. Hopefully ill manage to get a few community contributions and get the ball rolling, i've made it as easy as I could to add support for other resources without you even really having to know golang.

IAM isn’t fun, but there’s lots of options.

https://pypi.org/project/access-undenied-aws/ will allow you to start with least privilege and fix specific issues.

https://github.com/iann0036/iamlive allows an admin to perform the action via CLI and capture the policy.

Access advisor can inspect how you actually use the role and give suggestions on what to remove.

A more helpful suggestion is to experiment with these tools and then find gaps in IAM actions and submit those as feature requests via your TAM.

‍Pike is a tool that analyzes Terraform managed resources and automatically generates the necessary IAM permissions, improving security by ensuring that only the minimum necessary permissions are granted.

I test out the Api the hard way, I make a resource and test it with a role that doesnt have the permissions (see the folder i linked), the Api (with azure anyway) tells you what you lack, azure tends to be simpler with crud permissions than aws. I then have another privilege tole that can update the first with each permission and iterate: https://github.com/JamesWoolfenden/pike/tree/master/terraform/azurerm, i then create the mapping file for that resource and add it. I can show you if you need help - send me an email/message/zoom. If you figure a better way i'm all ears, but this way I can be sure on what permissions are required.

You can run my tool pike on your tf to generate iam for aws and gcp. Get it here https://github.com/jamesWoolfenden/pike

I wrote a small tool called Pike. It looks at your TF code and determines and create the IAM policy/Tf resource required to build it. To help you stick to least privilege in your build process. It currently supports a small but growing sub-set of AWS resources, it will support other providers. Use it or ?, but would welcome feedback https://github.com/JamesWoolfenden/pike . Its open source and always will be.
