scheduler.amazonaws.com is missing. It's a new service which recently added
https://docs.aws.amazon.com/scheduler/latest/UserGuide/setting-up.html

Audit Manager service principal, which is auditmanager.amazonaws.com .

reachabilityanalyzer.networkinsights.amazonaws.com has recently been added for the fairly new Network Manager Reachability Analyzer. Now supports delegated administrator functionality for cross-account analyses.

scheduler.amazonaws.com is missing. It's a new service which recently added https://docs.aws.amazon.com/scheduler/latest/UserGuide/setting-up.html

Thanks for this

ecr.amazonaws.com is wrong.

You can either have,

• pullthroughcache.ecr.amazonaws.com
• replication.ecr.amazonaws.com

resource.cloudformation.amazonaws.com
hooks.cloudformation.amazonaws.com

Reference: https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/registry-public.html

Small typo introduced here -- should be resources.cloudformation.amazonaws.com instead

dms.amazonaws.com should be dms.region-name.amazonaws.com.

Source: I was furiously searching for this and found it deep in https://docs.aws.amazon.com/dms/latest/userguide/security_iam_secretsmanager.html

dms.amazonaws.com should be dms.region-name.amazonaws.com.

Does anyone know when should we reference the global endpoint and when the regional endpoint ?

I have found referencing one or the other in some IAM polices.

This list seems to be / have become a mix of AWS Service Principals and service endpoints. Is there a clear way to separate the two?

https://docs.aws.amazon.com/IAM/latest/UserGuide/reference_aws-services-that-work-with-iam.html tables' service-linked role column's ``Yes` link will lead to pages documenting service principals. The docs don't follow a convention when marking up principals so parsing would need be regex based and walk through many pages.

https://docs.aws.amazon.com/service-authorization/latest/reference/reference.html service authorization reference lists the service prefix for all services in a parsable form. I've extracted service names before from these pages.

The service principals are doable, just need to follow links and grep for principal looking strings. Still room for error and I for one can't be bothered, but perhaps someone else has the time to script it and run on CI for an up-to-date list.

List above updated!

bedrock.amazonaws.com

Now a CloudWatch alarm can send an event directly to a Lambda Function. This is the principal: lambda.alarms.cloudwatch.amazonaws.com

I added malware-protection.guardduty.amazonaws.com as mentioned here:
https://docs.aws.amazon.com/organizations/latest/userguide/services-that-can-integrate-guardduty.html

Updated everything up to here. Honestly y'all, I tried years ago to get AWS to support this .

I'll look at putting together a repo. We would need to automate that repo updating this gist to maintain the friendliness of this being the top result on google for "list of AWS service principal" and related searches.

Wondering, is this gist already updated automatically in some way? It seems like whenever I come here it says something like last active x hours ago. 😸

I would like to suggest a pontential way to partially automate this. Searching through all AWS Managed IAM policies I get a list of 203 unique domains:

$ git clone --depth=1 https://github.com/udondan/iam-floyd

I am not too deep into this topic, so not sure if all those matches are actually valid service principals...

This list is sorted by the number of occurences. Haven't checked the inersection with your list.

how about getting from this - https://awspolicygen.s3.amazonaws.com/js/policies.js

bharathkumardasaraju@~$ curl -s https://awspolicygen.s3.amazonaws.com/js/policies.js | sed 's/.*app.PolicyEditorConfig=//' | sed 's/};/}/' | jq -r '.serviceMap | to_entries[] | select(.value.StringPrefix != null) | .value.StringPrefix + ".amazonaws.com"' | sort | uniq | wc -l

SNS to Lambda integration introduces opt-in region specific service principals for SNS like sns.<opt-in-region>.amazonaws.com from https://docs.aws.amazon.com/sns/latest/dg/lambda-prereq.html

Chime introduces a meetings.chime.amazonaws.com service principal according to https://docs.aws.amazon.com/chime-sdk/latest/dg/mtgs-sdk-notifications.html

For AWS CloudFormation StackSets there are two principals (only one listed above):

1. stacksets.cloudformation.amazonaws.com (missing one)
2. member.org.stacksets.cloudformation.amazonaws.com

Source: https://docs.aws.amazon.com/organizations/latest/userguide/services-that-can-integrate-cloudformation.html#integrate-enable-svcprin-cloudformation

The principal stacksets.cloudformation.amazonaws.com is not recognized for me when trying to enable Trusted Access using the CLI/CDK. I get the following error:
[FAILED] from custom resource. Message returned: You specified an unrecognized service principal
