I'm seeking advice on how organizations typically handle user requests for updating existing permissions in IAM roles or creating new roles. Currently, our small IAM team, consisting of just three members, is overwhelmed with numerous requests from users for changes to their AWS roles. This can be quite challenging since we often lack the context to determine the precise permissions needed. While we strive to maintain least-privilege access, the process usually involves multiple rounds of troubleshooting. I'm curious about how we can streamline this process effectively and whether there are standard approaches for centralizing access requests while ensuring security. Any insights, tips, or examples from real-world experiences would be greatly appreciated!

Making the process more self-service is key. You really want to build out your architecture so that it minimizes failures. Manual work is often a bottleneck, especially when people are just designated to judge changes without having the proper context. Using Service Control Policies (SCPs) and Infrastructure as Code (IaC) can help create isolated environments or sandboxes for experimentation, which could really smooth out the wrinkles in your current process. It's all about adapting to your organization's culture and needs.
Navigating permissions can get tricky! Here are my go-to strategies:
1. Create generic permission sets to avoid chaos from endless custom permissions. For instance, use clear roles like PowerUser, ReadOnly, and SecurityAdmin based on business needs.
2. Have a dedicated team with admin access to manage user requests. This is usually the DevOps or SRE team, which helps keep things orderly. Users often complain about being ‘blocked,’ but it just maintains stability.
3. Rely on automation for group mapping. Manually managing SSO access can quickly become unmanageable; automations will save you a lot of hassle.
4. Ensure all resources have clear owners to prevent bottlenecks in decision-making. You want those with the right context to manage permissions effectively.
5. Make use of Just-In-Time (JIT) provisioning for permissions that are needed only occasionally rather than granting blanket access.
6. Lastly, remember that permissions should generally differ by environment. For example, you might allow full access in Sandbox but employ tighter controls in production.
This is solid advice! I'm particularly interested in how you maintain least privilege while grouping teams. Do you customize roles per team?
It really varies by organization, but here's how we handle it:
1. Generally, users have minimal permissions outside of development, and we allow quite a bit of freedom within development boundaries.
2. For formal environments, we define clear roles that are tied to business activities rather than just random collections of permissions. So when someone asks for a permission update, it leads to a meaningful discussion.
3. Create a good separation between design and execution to keep things organized; this helps immensely with scaling permissions.
I know it's a high-level answer, but implementing this structure has really helped our team manage permissions more effectively.
Could you share specific examples of how you've seen self-service work in practice? That would be super helpful!
