A technician is hardening a newly imaged Windows 11 workstation before it is connected to the corporate network. Which of the following actions will BEST mitigate attacks that rely on publicly documented default credentials?
Turn off User Account Control (UAC) prompts for administrators.
Install the latest cumulative Windows updates.
Enable file and printer sharing on the private network profile.
Rename or disable the built-in Administrator account and set a complex password.
Renaming or disabling the built-in Administrator account and assigning it a strong, unique password prevents attackers from logging in with manufacturer-supplied default usernames and passwords that are widely published online. Although applying patches, enabling sharing, or lowering UAC settings affect system behavior, none specifically address the threat of default credentials being exploited.
