We looked into different policies when discussing users, groups, and roles in the previous chapter. So now, we will dive deeper into these policies and discuss the various different types of policies and what they look like.
Policies are associated with users, groups, roles, or resources and define who or what can or can’t access AWS resources. You may already be familiar with some policy types, but AWS supports a number of different types of policies, including the following:
- Identity-based policies
- Resource-based policies
- Permissions boundaries
- Access Control Lists (ACLs)
- Organization Service Control Policies (SCPs)
We will discuss these policies one by one in the following subsections.
