"Some users question whether sudo is less secure than
su. Because both rely on passwords, they share the same strengths
and weaknesses. If the password is compromised, the system is
compromised. However, if the password of a user who is allowed by
sudo to do one task is compromised, the entire system may not be at
risk. Thus, if used properly, the finer granularity of sudo's
permissions structure can make it a more secure tool than su. Also,
when sudo is used to invoke a single command, it is less likely
that a user will be tempted to keep working with root privileges
than if the user opens a root shell with su."
