Main Concerns

Authentication

Since this might be run in production, permissions should be assigned to the script, and not necessarily to the user executing the script.

The first step in developing the script, is to make sure authentication is configured properly.

I'm using Microsoft Graph API in PowerShell, and so I've followed MS's guide on setting up Application authentication.

Logging

Logging seems to be an imperative aspect of the task, so I started by thinking about how do I track the operations.

I came up with 2 clasess:

• LogEntry - containing the relevant details for each action. This includes:

  [DateTime]Timestamp
  [String]Operation
  [String]OperationDescription
  [TimeSpan]Duration
  [String]FinalStatus
  

• LogTrail - A class to manage the logs typed list within it.

These classes allow me to easily manage logs in a consistent pattern.

Script logic

1. The first thing the script will do is test a connection has already been established.
2. Create the group if it does not already exist.
3. Iterate through the list of users, for each
   • If the user doesn't exist, it will create the user.
   • If the user isn't a member of the above mentioned group, add it to it.
4. Display the report.
