iamlive VS parliament

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.

All of the sdks support client side monitoring (CSM), so these sort of tools can be built client side. https://boto3.amazonaws.com/v1/documentation/api/1.10.46/gui...

afaics the only challenge is mapping some of the apis to iam as its only 85% 1:1

There's also tools for helping with iam like (generator, and linter)

https://github.com/salesforce/policy_sentry

https://github.com/duo-labs/parliament

There are IAM linting libraries like parliament (https://github.com/duo-labs/parliament) that can be used to build a solution like the one you described. There are also some other open source tools that use it for security purposes. You'd probably have to customize them for use in your own CICD processes.

No API, but you can generate JSON output using https://github.com/duo-labs/parliament (or a modified version that includes undocumented actions at https://github.com/iann0036/iam-dataset/blob/main/iam\_definition.json).

Sift through 9000+ privileges in just a few key presses, ARN's are instantly recommended and their input/validation is streamlined. Additional statements can be added via hotkey, and your policy will be checked in real-time for syntax errors or other bugs (thanks Parliament!).

I've been literally tweeting at aws for a long time now for a tool like this lol, haven't found anything. but you can play around with Parliament
