 ## Lab
 - [x] create a custom IAM Policy
 - [x] create an IAM Role for EC2

  * HTTPS outbound was not set up
    * I did not check outbound rules (even when the lab explicitly called this out)
      because it mentioned lab 2, so my assumption was that it had already been set up
      (it was not). When connection to s3 failed I double checked lab 3 instructions

 ### Stretch
 - [x] Create a bucket policy that blocks all public access but allows your IAM role
  - [ ] Implmented: [guide](https://aws.amazon.com/blogs/security/how-to-restrict-amazon-s3-bucket-access-to-a-specific-iam-role/)

+- [x] **Experiment** with requiring MFA or VPC conditions.
+  - [x] MFA conditions
    * MFA did not work out of the box after setting it in the s3 bucket policy. 
      The ways I found you can configure MFA:
-      * [stackoverflow](https://stackoverflow.com/questions/34795780/how-to-use-mfa-with-aws-cli)
-      * [official guide](https://docs.aws.amazon.com/IAM/latest/UserGuide/id_credentials_temp_use-resources.html)
-      * via cli roles
-      * configuration via ~/.aws/credentials
-      * 1Password CLI with AWS Plugin
-        * I use bitwarden, which also has an AWS Plugin
-        * This is probably what I will gravitate towards for a more 
-          long-term setup, because having all of these credentials
-          floating around in various areas on my computer/virtualbox
-          envs gets confusing. Not a fan.
-        * I've seen a lot more recommendations (TBH it's more like 2 vs 0)
-          for 1password for password credential setup. Wonder why?
-      * other apps that handle this
-  - [ ] VPC
+    * [stackoverflow](https://stackoverflow.com/questions/34795780/how-to-use-mfa-with-aws-cli)
+    * [official guide](https://docs.aws.amazon.com/IAM/latest/UserGuide/id_credentials_temp_use-resources.html)
+    * [x] via cli roles - I set up a new set of role-trust relationships.
+      Update s3 Role: 
+        Update action: sts:assumerole 
+        Update principle (for user -- could not target group)
+        Add condition (MFA bool must be true)
+    * Commands referenced: I set up a script that looks like this

- [ ] **Host a static site**
-  - [ ] Enable a static website hosting (`index.html`)
-  - [ ] Configure route 53 alias or CNAME for `resume.<yourdomain>` to the bucket endpoint.
-  - [ ] Deploy CloudFront with ACM certificate for HTTPS

 ## Reflection
 * What I built
 * Challenges
+  * Groups cannot be used as the principal in a trust relationship
+  * The stretch goal for setting up s3 + mfa was a bit of a pain:
+    * The earlier lab had me set up a trust relationship on the role to allow EC2 as a principal
+      on the role
+      When I later updated IAM permissions to include MFA, I promptly forgot about this detail
+      and had chatgpt help me with troubleshooting. It was pretty good at helping me figure out
+      the issue
+    
 * Security concerns
  On scale and security at scale
