The lesson

Least privilege means each person has only the access their work requires. Daily work uses a standard account; administrator rights are used separately and rarely.

Manage the account lifecycle: create accounts when people join, adjust when roles change, and disable them on the day people leave.

Avoid shared accounts; where unavoidable, store the password in a shared vault and change it when someone leaves.

Step by step

  1. Create standard and admin accounts on the lab computer.
  2. Review who has admin rights.
  3. Write a leaver checklist.
  4. Plan replacement of shared accounts.

Practice activity

Write the account lifecycle procedure.

Expected result: A procedure covering joiners, movers and leavers with admin rights minimised.
