๐ฅ Account Management
Who should exist, who shouldn't, and who's an adminโฑ ~3 min
One of the highest-scoring areas in CyberPatriot is account management. The scenario will tell you which users are authorized โ everyone else should be removed.
Account Types
| Account Type | Description | Competition Risk If Mismanaged |
|---|---|---|
| Administrator | Full control โ can change security settings, install software, access all files | Too many admins = vulnerabilities; remove unauthorized admins |
| Standard User | Normal daily tasks; cannot change system settings | Correct for most users |
| Guest | Minimal permissions, no password by default | Must be disabled โ it's always a vulnerability |
| Built-in Administrator | Hidden default admin account on all Windows installs | Rename it, give it a strong password, and restrict use |
