# Audience in CodeGuru Profiler
Audience

How you use AWS Identity and Access Management (IAM) differs based on your role:
+ **Service user** - request permissions from your administrator if you cannot access features (see [Troubleshooting CodeGuru Profiler identity and access](security_iam_troubleshoot.md))
+ **Service administrator** - determine user access and submit permission requests (see [Overview of managing access permissions to your CodeGuru Profiler resources](security_iam_service-with-iam.md))
+ **IAM administrator** - write policies to manage access (see [Customer managed policy examples](auth-and-access-control-iam-identity-based-access-control.md#security_iam_id-based-policy-examples))
