1. Consider two configurations of a desktop computer using Linux as operating system:

   • Scenario A uses a separate user account with standard privileges and a root account with a different password. The main user knows both passwords.

   • Scenario B uses sudo (e.g., a run as administrator feature) that allows the regular user to run programs, after confirmation as root. The user does not know the password for the root account.

     Considering the scenarios A and B, does the use of sudo (or a similar system) improve the overall system security. Briefly argue either way.
