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.
