Explanation:
Rename administrator account policy setting determines whether a different account name is associated with the security identifier (SID) for the Administrator
account.
Because the Administrator account exists on all Windows server versions, renaming the account makes it slightly more difficult for attackers to guess this user
name and password combination. By default, the built-in Administrator account cannot be locked out no matter how many times a malicious user might use a bad
password. This makes the Administrator account a popular target for brute-force password-guessing attacks.
The value of this countermeasure is lessened because this account has a well-known SID and there are non-Microsoft tools that allow you to initiate a brute-force
attack over the network by specifying the SID rather than the account name. This means that even if you have renamed the Administrator account, a malicious user
could start a brute-force attack by using the SID.
Rename the Administrator account by specifying a value for the Accounts: Rename administrator account policy setting.
