# Audience for Amazon IoT SiteWise security
Audience

How you use Amazon Identity and Access Management (IAM) differs based on your role:
+ **Service user** - request permissions from your administrator if you cannot access features (see [Troubleshoot Amazon IoT SiteWise identity and access](security_iam_troubleshoot.md))
+ **Service administrator** - determine user access and submit permission requests (see [How Amazon IoT SiteWise works with IAM](security_iam_service-with-iam.md))
+ **IAM administrator** - write policies to manage access (see [Amazon IoT SiteWise identity-based policy examples](security_iam_id-based-policy-examples.md))
